Nitrous oxide (N₂O)—commonly used in dentistry and surgery for its anesthetic and calming effects—has long been considered safe for short-term use. However, for some individuals, a single exposure can trigger a silent storm in the brain, especially when combined with hidden deficiencies in vitamin B12, folate (B9), and other B vitamins or subtle methylation impairments.This article explores how nitrous oxide can interfere with a critical enzyme called methionine synthase (MTR), disrupt methylation, and potentially contribute to long-term neurological damage that’s often mistaken for normal aging—or even dementia.<h3>🧬 What MTR Does and Why It Matters</h3>MTR (methionine synthase) is a vital enzyme that keeps your methylation system running—this is the system your body uses to switch genes on and off, build brain chemicals like serotonin and dopamine, and detoxify harmful substances. MTR depends on the active form of vitamin B12 (called methylcobalamin) to perform its job. It takes homocysteine—a potentially dangerous waste product—and recycles it into methionine, an amino acid your body needs to make SAMe. SAMe is your body’s universal methyl donor, fueling everything from mood balance and hormone metabolism to liver detox and inflammation control. This same process also regenerates tetrahydrofolate (THF), a reusable form of folate essential for healthy DNA production and repair—especially in fast-dividing cells like those in your brain, gut, and immune system.When MTR activity is impaired, homocysteine builds up, while methionine and SAMe decline. This is like trash piling up when the garbage truck breaks down and the repair shop is closed. Homocysteine itself is toxic—it can inflame blood vessels, damage nerves, and interfere with brain chemistry. Over time, this disrupts neurotransmitter synthesis, brain function, mood regulation, and cellular repair.<h3>🧯 How Nitrous Oxide Disrupts MTR </h3>Nitrous oxide irreversibly oxidizes the cobalt atom in vitamin B12, rendering methylcobalamin inactive. Once B12 is inactivated, MTR stops functioning, halting the entire methylation process. Homocysteine levels rise, SAMe drops, and the brain becomes vulnerable to inflammation, oxidative stress, and demyelination.This biochemical disruption isn't temporary in some people—especially those with pre-existing low B12, MTR gene variants, or methylation impairments. It can linger for months or even years, causing symptoms that are often labeled as anxiety, depression, or early cognitive decline.🐒 Animal Evidence: Studies have highlighted MTR’s role in neurological health. Monkeys exposed to nitrous oxide—a known inhibitor of MTR—developed neurological disease resembling human B12 deficiency and cognitive impairment. These symptoms were partially rescued with methionine supplementation, suggesting that impaired methionine synthesis may be the root driver of neurodegeneration, even more so than B12 depletion itself.<h3>🧪 Symptoms to Watch For In humans</h3>MTR inhibition has been linked to symptoms such as:<ul><li>Memory loss or cognitive decline</li><li>Jittery movements (such as lip twitching)</li><li>Mood swings, anxiety, or depression</li><li>Neuropathy or muscle weakness</li><li>Unexplained fatigue or poor coordination</li></ul>These can appear days to weeks after nitrous oxide exposure and may become permanent if the underlying issue goes unrecognized.⚠️ Could This Explain Your Loved One’s Symptoms? If your family member experienced sudden or memory loss, mood changes, or neurological symptoms after a medical or dental procedure involving nitrous oxide, it may not have been “just aging.” A single exposure in a susceptible person—especially someone with undiagnosed B12 issues—can cause long-term neurological effects. And because standard testing often misses this, the root cause can go overlooked for years.📋 What Labs Often MissMost routine blood tests only measure total B12 in the bloodstream, not how much is active or usable inside your cells. This means results can appear normal even when a functional deficiency is present. More accurate insight comes from testing functional markers like methylmalonic acid (MMA) and homocysteine. However, even these can be misleading—especially homocysteine—if the blood sample isn’t handled properly after collection.⏱️ Homocysteine Lab Handling Matters After a blood draw, red blood cells continue releasing homocysteine into plasma unless the sample is separated within 30 minutes. This delay can cause artificially elevated levels—but what’s most often overlooked is that mishandled samples can also mask a true deficiency. In fact, the bigger danger is a false negative, where poor processing leads to a misleadingly normal result. This can cause clinicians to miss a serious methylation problem or B12 deficiency altogether.📈 Recovery and Hope The good news is that when caught early, the effects of MTR disruption and elevated homocysteine can often be reversed. Supportive nutrients like methylcobalamin (active B12), methionine, and other methylation co-factors can restore balance, lower homocysteine, and help protect brain function and cellular health.Key steps include:<ul><li>Testing homocysteine and MMA</li><li>Supplementing with active B12 and folate</li><li>Supporting detoxification and mitochondrial function</li><li>Avoiding further nitrous oxide exposure</li></ul><h3>🧠 Final Thoughts</h3>Nitrous oxide is not considered dangerous—but it’s not benign either. In susceptible individuals (my mother), even a single exposure can set off a cascade of biochemical events that compromise brain function, energy metabolism, and neurological stability. The good news? With awareness, early testing, and targeted nutritional support, many of these effects can be reversed—or even prevented entirely.Unfortunately, most family doctors and neurologists are not trained to recognize this kind of metabolic disruption. They may never ask about nitrous oxide exposure or consider functional B12 status. That’s why sharing this information and advocating for better testing is essential.NOTE:This article is designed to inform clinicians and the general public about a significant hidden risk factor in neurological disease that’s easy to overlook but just as easy to address with the right knowledge.If you suspect this might be part of your or a loved one’s story, contact a functional medicine practitioner for deeper evaluation and support.

Nitrous Oxide and the Hidden Link to B12-Related Cognitive Decline

If you have ever struggled with fatigue, anxiety, depression, hormone imbalance, moodiness, brain fog, or sluggish detox, you’ve likely been told to eat better, take some B vitamins, test your hormones, or take some medication. And around and around you go.But what if the real issue lies upstream? What if there’s a system that connects all of those issues at the cellular level that you’ve never even heard of? Welcome to the Methylation Network.<h3>What Is Methylation?</h3>Methylation is a biochemical process that happens over a billion times per second in every cell in your body. It’s how your body adds tiny chemical tags (called methyl groups) to DNA, hormones, neurotransmitters, and more.This simple act of “tagging” controls:🧬👉 How your genes are expressed 👉 How neurotransmitters are produced and broken down 👉 How toxins are neutralized and excreted 👉 How hormones are metabolized 👉 How your immune system regulates inflammation 👉 How your mitochondria generate energy And yet… methylation dysfunction is one of functional medicine's most overlooked root causes.<h3>Methylation Is More Than One Pathway</h3>Most people only hear about MTHFR or the folate cycle. But methylation is a network of 5 interconnected cycles regulating nearly every aspect of your biology. Let me introduce them.The 5 Interconnected Cycles of Methylation: 1. 💧The Urea Cycle: Clears ammonia and excess nitrogen from protein metabolism. It can cause fatigue, nausea, irritability, and ammonia buildup when impaired.2. 🧠The BH4 (Neurotransmitter) Cycle: Produces serotonin, dopamine, melatonin, and nitric oxide. This cycle impacts mood, blood flow, sleep, and neurotransmitter balance.3. 🥬The Folate Cycle: Converts folate into 5-MTHF, the active methyl donor. This is where MTHFR lives and where methylation begins.4. 🔥The Methionine Cycle: Produces SAMe, the body’s universal methyl donor. It supports DNA methylation, hormone detox, and inflammation control.5. 🛡️The Transsulfuration Cycle: Converts homocysteine into glutathione (your master antioxidant). This cycle is critical for detox, redox balance, and immune health.Each cycle is nutrient-dependent and tightly interconnected. If one slows, the whole system struggles.And when that happens?Methylation dysfunction can manifest as everything from mood disorders and hormonal chaos to cardiovascular issues, chemical sensitivities, or autoimmune diseases.<h3>What’s Coming in This Series </h3>Over the next several articles, I will break down these five cycles in plain English with diagrams, clinical pearls, and real-world examples to help you connect the dots.We’ll start with the🔥Methionine Cycle, where the real work of methylation happens. The body creates SAMe, one of the most important molecules for mood, detox, and DNA repair.👉 If you’re a practitioner, this series will sharpen your clinical lens.👉 If you’re a patient or a curious learner, it may finally explain the symptoms no one else has been able to connect.🔓 Let’s unlock methylation.📘From the author of Methylation Unlocked: The Missing Link to Health, Hormones, and Healing—coming soon.

Berberine: A Gut Health Game-Changer with Amazing Benefits

<h3>FOR IMMEDIATE RELEASE</h3>CANADA, May 6, 2024 - Functional Medicine Consulting, led by highly respected stomach acid expert Sandy Rideout (Doc SIBO), revealed groundbreaking findings that challenge conventional medical understanding of acid reflux and digestive disorders. After extensive clinical research using the Heidelberg pH Diagnostic System on over 80 patients, Rideout has discovered that less than 2% of people actually have high stomach acid - contradicting the widespread prescription of acid-blocking medications.This revelation directly challenges the foundation of conventional gastroenterology, which typically treats acid reflux symptoms with proton pump inhibitors (PPIs) and other acid-suppressing medications. According to Rideout's research, the vast majority of patients with acid reflux symptoms actually have insufficient stomach acid (hypochlorhydria), not the excess that has been presumed for decades."My testing with the Heidelberg pH Diagnostic System has definitively proven low to no stomach acid in those individuals with acid reflux who are not taking PPIs," states Rideout. "This fundamentally changes how we should approach digestive health and explains why so many patients continue to struggle despite conventional treatments."The implications of this discovery extend far beyond simple digestive discomfort. Rideout's findings reveal that low stomach acid disrupts digestion from start to finish, creating a cascade of health issues including poor nutrient absorption, microbial imbalances, and systemic inflammation - ultimately contributing to conditions that conventional medicine typically treats as separate, unrelated disorders.<h3>Breaking the Medication Cycle </h3>Perhaps most concerning is Rideout's evidence that acid-blocking medications often worsen the very conditions they're prescribed to treat. His clinical observations show that PPIs and similar medications create a vicious cycle: by further suppressing already low stomach acid, they impair digestion, allowing food to ferment in the stomach, which creates pressure and causes the lower esophageal sphincter to relax or weaken, resulting in acid reflux symptoms."When patients try to stop PPIs, they often experience worse reflux due to rebound acid hypersecretion," Rideout explains. "This makes them believe they need the medication for life, when in reality, they're trapped in a cycle that's making their underlying problem worse."Additionally, long-term PPI use contributes to serious downstream effects, including bacterial overgrowth, nutrient deficiencies, potential increased risk of infections, and even connections to autoimmune conditions through compromised gut integrity, a leaky gut.Ironically, while PPIs are designed to suppress acid, they may not fully prevent acid reflux—especially non-acidic or weakly acidic reflux—which can still cause chronic inflammation in the esophagus. Over time, this ongoing irritation can increase the risk of developing Barrett’s esophagus, a condition that may progress to esophageal cancer in some individuals.<h3>Connecting Previously Unconnected Conditions </h3>Another significant aspect of Rideout's work is establishing the connection between stomach acid function and seemingly unrelated health conditions. His research demonstrates that optimizing stomach acid levels has led to improvements in autoimmune conditions, neurological issues, hormonal imbalances, and chronic inflammatory disorders."Many separate conditions—whether autoimmune, neurological, hormonal, or inflammatory—trace back to poor digestion, nutrient deficiencies, and gut dysfunction," notes Rideout. "Optimizing stomach acid doesn't just relieve bloating and GERD—it corrects the root cause of widespread health issues that conventional medicine has failed to connect."This understanding has given Rideout a competitive edge in treating "medical mystery" patients—those who have seen multiple specialists without finding resolution. One dramatic example involved a 47-year-old woman with severe fatigue, brain fog, chronic pain, and digestive distress who had been struggling for over a decade. After optimizing her stomach acid levels, all of her symptoms began improving simultaneously, revealing that her fibromyalgia, chronic fatigue, and digestive issues weren't separate conditions but interconnected problems stemming from the same root cause, low stomach acid.<h3>Comprehensive Testing Protocol Reveals Hidden Connections </h3>Rideout's diagnostic approach goes beyond the Heidelberg test, incorporating multiple functional assessments to identify downstream effects of low stomach acid:<ul><li>The Betaine HCl Challenge Test, which reveals a patient's response to supplemental stomach acid </li><li>Hair Tissue Mineral Analysis to identify mineral imbalances linked to poor stomach acid levels </li><li>Organic Acids Test to detect metabolic byproducts indicating bacterial overgrowth and poor digestion </li><li>Comprehensive Stool Analysis to assess gut pathogens, digestion markers, and microbiome balance </li><li>Serum Nutrient Testing to identify deficiencies caused by malabsorption </li></ul>"By connecting these dots, we get a complete picture of how low stomach acid affects the entire body," Rideout says. "This comprehensive approach has allowed us to resolve cases that have stumped other practitioners for years."<h3>Natural Solutions Without Supplement Dependency </h3>Unlike many functional medicine approaches that rely heavily on supplements, Rideout emphasizes restoring optimal stomach acid function using necessary Betaine HCl with pepsin and dietary and lifestyle modifications."Restoring stomach acid isn't about taking pills indefinitely," Rideout emphasizes. "It's about training the body to produce what it needs naturally through specific behavioral changes, dietary adjustments, and addressing the root causes of acid suppression."His protocol includes teaching patients to activate the initial stage of digestion through thorough chewing and mindful eating, optimizing meal timing and composition, incorporating acid-stimulating bitter foods, managing stress through vagus nerve stimulation, and restoring proper circadian rhythms—all factors that directly influence stomach acid production.<h3>Challenging Prevalent Medical Misconceptions </h3>Rideout's work directly challenges several deeply entrenched misconceptions in conventional medicine:<ul><li>The belief that GERD and acid reflux are caused by excessive stomach acid </li><li>The assumption that stomach acid causes ulcers and should be suppressed </li><li>The notion that stomach acid only affects digestion with no impact on systemic health </li><li>The misconception that digestive enzymes and bile flow function effectively regardless of stomach acid levels&nbsp;</li></ul>"The medical system focuses on symptom suppression rather than root causes," Rideout states. "This is why so many misconceptions about stomach acid persist despite clear evidence to the contrary. By testing actual stomach acid levels rather than assuming excess acid based on symptoms, we get a completely different picture of what's truly happening in the digestive system."Rideout has solidified these connections in his SIBO MIND MAP©, a comprehensive resource that illustrates how stomach acid serves as a critical foundation within the broader framework of gut health. The map shows how stomach acid acts as a gatekeeper preventing unwanted bacteria from entering the small intestine, signals proper motility to prevent bacterial overgrowth, triggers bile and enzyme release, and plays a crucial role in preventing immune dysregulation and systemic inflammation.<h3>A Paradigm Shift in Functional Medicine </h3>By identifying stomach acid optimization as a root factor in resolving numerous health conditions, Rideout's work represents a paradigm shift in functional medicine. His approach demonstrates that addressing this single foundational aspect of digestion can create cascading positive effects throughout the body."Most practitioners miss this critical connection," Rideout concludes. "When we optimize stomach acid, we're not just fixing digestion—we're restoring the body's natural defense mechanisms, absorption capabilities, and metabolic functions. This is the foundation of true health that has been overlooked for too long in conventional and even traditional medicine."For those suffering from chronic digestive issues, unexplained symptoms, or conditions that haven't responded to conventional treatments, Rideout's findings offer a compelling new direction and hope for resolution by addressing a fundamental but frequently overlooked aspect of human physiology.About Functional Medicine ConsultingFunctional Medicine Consulting, founded by Sandy Rideout (Doc SIBO) in 2013, specializes in identifying and addressing the root causes of complex digestive health issues, with particular expertise in small intestinal bacterial overgrowth (SIBO) and stomach acid optimization.

Functional Medicine Specialist Exposes Paradox in Digestive Health: Challenging Conventional Treatment of Acid Reflux

Stocking up on the best products in the pharmaceutical industry

<h3>Introduction</h3>Proton Pump Inhibitors (PPIs) are among the most commonly prescribed medications for acid-related conditions, including acid reflux, heartburn, and gastric ulcers. Their ability to suppress stomach acid production effectively relieves symptoms, making them a go-to treatment for millions worldwide. However, while PPIs are highly effective in reducing symptoms, their long-term impact on stomach health is often overlooked.Despite the widespread belief that excess stomach acid is the primary cause of reflux and ulcers, true hyperchlorhydria (excess acid production) is rare, affecting less than 2% of the population. In reality, the vast majority—more than 98%—of individuals experiencing reflux, heartburn, or even the early stages of gastric ulcers have low or no stomach acid production. This misconception has led to the widespread overuse of PPIs, which further reduce acid levels, worsening digestive function rather than addressing the root cause.Chronic PPI use disrupts the stomach's natural acidity, impairing digestion, nutrient absorption, and gut microbiome balance. Over time, this suppression can lead to complications such as bacterial overgrowth, malabsorption, and increased infection vulnerability. Understanding these long-term consequences is crucial for patients and healthcare providers when considering PPI therapy.<h3>The Physiology of a Healthy Stomach</h3>The stomach is a vital organ that plays a central role in digestion, acting as a storage chamber and a processing center for food. It secretes gastric juices that break down food, absorb certain nutrients, and serve as the first defense against harmful microbes. A properly functioning stomach ensures efficient digestion and nutrient absorption, but when its delicate balance is disrupted—such as by long-term Proton Pump Inhibitor (PPI) use—digestive health suffers.<h3>The Structure of the Stomach</h3>The stomach is a muscular, J-shaped organ between the esophagus and the small intestine. It has several distinct regions, each with specialized functions:<ul><li>Cardia: The upper portion where food enters from the esophagus. </li><li>Fundus: A dome-shaped area that stores undigested food and gases released during digestion. </li><li>Body: The main region responsible for mixing food with digestive juices. </li><li>Antrum: The lower section that grinds food into smaller particles before passing it to the small intestine. </li><li>Pylorus: The final part of the stomach, where the pyloric sphincter regulates the release of partially digested food into the small intestine. </li></ul>The stomach's inner lining contains folds called rugae, which allow it to expand as food enters. The lining is also home to gastric glands, which include different types of cells responsible for producing stomach acid, digestive enzymes, and protective mucus.<h3>The Protective Mechanisms of the Stomach </h3>Despite its highly acidic environment, the stomach has built-in protective mechanisms to prevent self-digestion and damage:<ul><li>Mucus Layer: Goblet cells in the stomach lining secrete a thick mucus that acts as a protective barrier against acid and digestive enzymes. </li><li>Bicarbonate Secretion: This neutralizes acid at the surface of the stomach lining, preventing irritation. </li><li>Tight Junctions Between Cells: These form a strong barrier that prevents acid from leaking into deeper layers of tissue. </li><li>Rapid Cell Turnover: The stomach lining regenerates every few days to repair any damage. </li></ul>When these defenses are weakened—whether due to chronic stress, infections like H. pylori, or long-term PPI use—the stomach becomes vulnerable to inflammation, ulcers, and other digestive issues.<h3>The Role of Stomach Acid in Digestion</h3>Stomach acid, hydrochloric acid (HCl), plays a fundamental role in digestion and overall health. Despite its reputation for causing discomfort when levels are imbalanced, adequate stomach acid is essential for breaking down food, particularly protein, absorbing nutrients, and protecting against infections.How Stomach Acid Facilitates Digestion Stomach acid serves as the first major step in chemical digestion. It helps break down food into smaller, more digestible components, ensuring that nutrients can be properly absorbed in the small intestine. Key digestive roles of stomach acid include:<ul><li>Protein Breakdown: Stomach acid activates pepsinogen, an inactive enzyme secreted by chief cells, converting it into pepsin—the active enzyme responsible for breaking down proteins into smaller protein fragments called peptides. </li><li>Food Liquefaction: Stomach (gastric) acid, combined with stomach contractions, transforms food into chyme, a semi-liquid mixture that can easily pass into the small intestine. </li><li>Nutr<span data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); background-color: rgba(249,250,251,var(--tw-bg-opacity));" style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); background-color: rgba(249,250,251,var(--tw-bg-opacity));">ient Release and Absorption: <em style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-weight: inherit; background-color: rgba(249,250,251,var(--tw-bg-opacity));" data-mce-style="font-family: inherit; font-size: calc(18px * var(--body-fontSize, 1)); font-weight: inherit; background-color: rgba(249,250,251,var(--tw-bg-opacity));">Certain nutrients, including iron, calcium, magnesium, zinc, and vitamin B12, require an acidic environment for proper absorption.</li></ul>The Cells Responsible for Acid Production The stomach contains specialized cells that work in harmony to regulate acid production:1. Parietal Cells: Located in the gastric glands of the stomach lining, these cells produce hydrochloric acid and intrinsic factor, a protein crucial for vitamin B12 absorption. 2. Chief Cells: These cells secrete pepsinogen, which requires stomach acid to be activated into pepsin for protein digestion. 3. Enteroendocrine Cells: These hormone-producing cells regulate acid secretion through various signaling molecules4. G cells: Found in the stomach's antrum secrete gastrin, which stimulates parietal cells to secrete acid and the ECL cells to release histamine, activating the parietal cells. 5. D Cells: These cells release somatostatin, the hormone that inhibits gastrin production when stomach acid levels are high, preventing excessive acid secretion. 6. Enterochromaffin-like (ECL) Cells: These secrete histamine, which binds to H2 receptors on parietal cells, directly triggering HCl secretion. Histamine is the primary direct stimulator of parietal cells' hydrochloric acid (HCl) secretion. However, these ECL cells require the hormone signal from gastrin for their secretion of histamine. Hierarchy of Acid Stimulation <ul><li>Histamine: The strongest direct trigger of acid secretion. Gastrin: Indirectly stimulates acid production by promoting histamine release. </li><li>Acetylcholine: This is released by the vagus nerve during the cephalic phase (when food is seen, smelled, or thought about). It amplifies the effects of both gastrin and histamine. </li></ul><h3>What Triggers Stomach Acid Release? </h3>Stomach acid production is tightly regulated and influenced by various factors including:<ul><li>The Cephalic Phase (Before Eating): The thought, smell, or taste of food signals the brain to stimulate the vagus nerve, which activates gastric acid secretion. </li><li>The Gastric Phase (During Eating): As food enters the stomach, stretch receptors detect the stomach's expansion, releasing gastrin from G cells further stimulating acid production. </li><li>The Intestinal Phase (As Food Leaves the Stomach): When chyme moves into the small intestine, hormones such as secretin and cholecystokinin (CCK) are released to slow acid production and regulate digestion. </li></ul><h3>Intrinsic Factor and Vitamin B12 Absorption </h3>Beyond acid production, parietal cells also secrete intrinsic factor, a glycoprotein essential for vitamin B12 absorption. Once B12 binds to intrinsic factor, it travels through the digestive tract and is absorbed in the ileum of the small intestine. Without sufficient stomach acid and intrinsic factor, vitamin B12 deficiency can develop, leading to neurological issues, fatigue, and anemia.<h3>The Consequences of Long-Term PPI Use&nbsp; </h3>Proton pump inhibitors (PPIs) are widely prescribed for acid-related conditions. However, their long-term use have significant consequences for stomach health. While they effectively suppress stomach acid production, this reduction in acidity disrupts essential digestive functions and leads to multiple downstream effects including:1. Impaired Protein Digestion and Nutrient Absorption Stomach acid is critical for breaking down proteins and activating digestive enzymes like pepsin. With reduced acid levels, protein digestion is incomplete, leading to malabsorption and potential deficiencies in amino acids. Additionally, stomach acid facilitates the absorption of key nutrients, including:<ul><li>Vitamin B12: Stomach acid releases B12 from food, allowing intrinsic factor to bind and transport it to the ileum for absorption. Long-term PPI use has been linked to B12 deficiency, which can contribute to neurological issues, fatigue, and anemia. </li><li>Iron: Stomach acid is necessary for converting dietary iron into a bioavailable form. Chronic suppression of stomach acid can lead to iron deficiency anemia. </li><li>Calcium and Magnesium: Reduced acid levels impair calcium and magnesium absorption, increasing the risk of osteoporosis and fractures. </li></ul>2. Increased Risk of Bacterial Overgrowth (SIBO) and Dysbiosis Stomach acid is a natural barrier against harmful bacteria entering the mouth and lower intestine. PPIs reduce this defense, allowing opportunistic bacteria to proliferate. This can contribute to:Small Intestinal Bacterial Overgrowth (SIBO): Excessive bacteria ferment carbohydrates, producing gas and leading to bloating, gas, diarrhea, or constipation. Dysbiosis: An imbalance in gut microbiota that can contribute to systemic inflammation, poor digestion, and increased susceptibility to infections. 3. Increased Risk of Infections With lower acid levels, the stomach becomes less effective at killing pathogens, increasing the risk of infections such as:<ul><li>Clostridioides difficile (C. diff): A bacteria that can cause severe diarrhea and colitis. </li><li>H. pylori Overgrowth: Though PPIs are sometimes used to treat H. pylori, long-term use can promote bacterial persistence and reinfection. </li><li>Respiratory Infections: Research suggests that long-term PPI use may increase the risk of pneumonia due to bacterial migration from the gut to the lungs. </li></ul>4. Increased Gastrin Production and Rebound Hyperacidity Because PPIs suppress acid, the body compensates by increasing gastrin production. This hormone directly and indirectly stimulates the parietal cells to produce more acid. Over time, this can lead to:1. Hypergastrinemia: Elevated gastrin levels, which can cause rebound acid hypersecretion when PPIs are discontinued, leading to worsened acid reflux symptoms. 2. Parietal Cell Hyperplasia: Chronic elevation of gastrin can enlarge acid-producing cells, increasing acid secretion if PPI therapy is suddenly stopped. 3. Stomach Lining Thickening: Long-term hypergastrinemia affects parietal cells and stimulates enterochromaffin-like (ECL) cells, which release histamine to further drive acid production. Over time, this persistent stimulation can cause ECL cell hyperplasia, contributing to the thickening of the stomach lining. 4. Potential for Gastric Polyps or Tumors: Prolonged exposure to high gastrin levels, particularly in individuals using PPIs for extended periods, has been associated with developing fundic gland polyps and, in rare cases, more serious gastric changes.<h3>Conclusion </h3>While PPIs provide effective short-term relief for acid-related conditions, their long-term use carries significant risks that should not be overlooked. Suppressing stomach acid alters digestion, nutrient absorption, and microbial balance, potentially leading to serious health consequences.

The Long-Term Impact of PPI Use on Stomach Health

After publishing yesterday's article, a few people reached out asking for more details on how low stomach acid actually works. I assume they are looking for the biochemistry behind it, but in layman's terms. Since biochemistry is my forte, I decided to write this follow-up article, diving deeper into the mechanisms of stomach acid and its impact on health. While I have covered this topic extensively in my published book, <a data-mce-href="https://www.amazon.com/dp/B0F26TW6ZC" href="https://www.amazon.com/dp/B0F26TW6ZC" target="_blank" rel="noopener">The Hidden Dangers of Low Stomach Acid available on Amazon</a> and my digital book on the website, I believe a more accessible breakdown will help clarify its importance.&nbsp;<h3>Introduction</h3>Many people assume that acid reflux, bloating, and indigestion stem from excessive stomach acid, but in reality, the opposite is true—insufficient stomach acid (hypochlorhydria) is a major underlying factor. Low stomach acid disrupts digestion from the start, creating a cascade of dysfunction that affects nutrient absorption, gut health, and systemic conditions like autoimmune disorders, chronic fatigue, and skin problems.This article discusses the physiological consequences of low stomach acid, its role in chronic health issues, and why addressing it will usually lead to significant symptom relief.<figure id="figure-ci9utbsnm8m8yr2nnp"><img id="ci9utbsnm8m8yr2nnp" src="https://media.gettyimages.com/id/2172901188/photo/human-stomach-internal-organ-concept-illustration.jpg?b=1&amp;s=2048x2048&amp;w=0&amp;k=20&amp;c=BuXuHbxAxEV0WgRhs7u21w_MzKOC9pIdVvuu7B4G-tQ=" alt="Human Stomach Internal Organ Concept Illustration" title="Human Stomach Internal Organ Concept Illustration" class="object-cover bg-gray-100 rounded-sm md:rounded-md lg:rounded-lg" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://media.gettyimages.com/id/2172901188/photo/human-stomach-internal-organ-concept-illustration.jpg?b=1&amp;s=2048x2048&amp;w=0&amp;k=20&amp;c=BuXuHbxAxEV0WgRhs7u21w_MzKOC9pIdVvuu7B4G-tQ=" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure><h3>Physiological Cascade of Low Stomach Acid</h3>1. Impaired Protein DigestionStomach acid is essential for activating pepsin, the enzyme that breaks down large proteins into smaller protein fragments called peptides. These peptides then move into the small intestine, where enzymes trypsin and chymotrypsin further break them down into even smaller peptides. Finally, brush-border enzymes called peptidases complete the breakdown of peptides into individual amino acids, which can then be absorbed into the bloodstream. Without sufficient stomach acidPepsin remains inactive, preventing proper protein breakdown. Undigested protein ferments and putrefies in the stomach, producing excess gas and increasing intra-abdominal pressure. This pressure usually leads to reflux and discomfort.Bloating, fullness, and reflux often occur after eating, symptoms that are frequently mistaken for excess stomach acid rather than insufficient acid. This misinterpretation can lead to the unnecessary use of acid-suppressing medications, further worsening digestion.Amino acid absorption is reduced, impacting critical functions such as muscle repair, neurotransmitter production, and immune system regulation. Over time, this deficiency can contribute to fatigue, mood imbalances, and increased susceptibility to infections.2. Delayed Gastric Emptying &amp; Reflux (GERD-like Symptoms)Low acid prevents the lower esophageal sphincter (LES) from closing properly. As undigested food ferments and produces gas, stomach contents are forced into the esophagus, mimicking acid reflux symptoms. This often leads to misdiagnosis and unnecessary acid-suppressing medications, which further worsen the problem.3. Small Intestinal Bacterial Overgrowth (SIBO)Stomach acid is a natural disinfectant, killing ingested bacteria and preventing their overgrowth in the small intestine. Without enough acid, bacteria migrate downward from the stomach into the small intestine, leading to small intestinal bacterial overgrowth (SIBO) and fermentation of undigested carbohydrates, leading to bloating, gas, and diarrhea/constipation).4. Poor Nutrient AbsorptionLow stomach acid leads to deficiencies in essential nutrients:<ul><li>Iron: Fatigue, hair loss, anemia. </li><li>Vitamin B12: Neuropathy, brain fog, mood disorders. </li><li>Calcium &amp; Magnesium: Osteoporosis risk, muscle cramps. </li><li>Zinc: Weak immunity, poor wound healing, and hair thinning. </li></ul>5. Gallbladder &amp; Pancreatic DysfunctionStomach acid triggers the release of cholecystokinin (CCK), a hormone that stimulates bile flow from the gallbladder and enzyme secretion from the pancreas. Stomach acid also triggers the release of secretin, a hormone that stimulates bile production in the liver, and the release of alkaline bicarbonates from the pancreas.Low stomach acid means weaker bile production and release, leading to poor fat digestion, gallbladder stagnation, and an increased risk of gallstones. Pancreatic enzyme secretion is also reduced, impairing carbohydrates and further protein breakdown, contributing to food intolerances and gut inflammation.6. Increased Risk of Gut Inflammation &amp; Leaky GutUndigested food particles and bacterial overgrowth irritate the gut lining, increasing intestinal permeability (leaky gut). This activates the immune system, triggering food sensitivities, autoimmune issues, and chronic inflammation.<figure id="figure-mt496lms7jm8yrkrj8"><img id="mt496lms7jm8yrkrj8" src="https://media.gettyimages.com/id/519756894/photo/pain.jpg?b=1&amp;s=2048x2048&amp;w=0&amp;k=20&amp;c=eeZpoXnDHxPWHGcigucqvoRuIrM4ys2vFnuglwTo1uY=" alt="Pain" title="Pain" class="object-cover bg-gray-100 rounded-sm md:rounded-md lg:rounded-lg" style="aspect-ratio: 16/9; object-position: undefined undefined;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://media.gettyimages.com/id/519756894/photo/pain.jpg?b=1&amp;s=2048x2048&amp;w=0&amp;k=20&amp;c=eeZpoXnDHxPWHGcigucqvoRuIrM4ys2vFnuglwTo1uY=" data-mce-style="aspect-ratio: 16/9; object-position: undefined undefined;"></figure><h3>Conditions Linked to Low Stomach Acid</h3>1. Autoimmune DisordersExamples: Hashimoto's, Rheumatoid Arthritis, Lupus<ul><li>Low stomach acid impairs protein digestion, leading to undigested food particles entering the bloodstream (leaky gut). </li><li>This triggers immune hyperactivity, increasing inflammation and autoimmunity. </li><li>Optimizing stomach acid helps restore gut barrier integrity, significantly reducing autoimmune flare-ups.</li></ul>Observed Improvement:<ul><li>Reduction in antibody levels (e.g., anti-TPO for Hashimoto's). Less joint pain &amp; fatigue in rheumatoid arthritis. </li><li>Stabilized blood sugar &amp; hormone function. </li><li>Reduced skin rashes &amp; fatigue in lupus and decreased inflammation markers (e.g., blood ANA levels).</li></ul>2.

Even though stomach acid is already low, some can still be in the stomach. When this acid refluxes into the esophagus (which has no protective lining), it causes burning and discomfort. PPIs and antacids neutralize or suppress acid, temporarily reducing the burning sensation and providing symptom relief—but not fixing the underlying issue (low stomach acid).PPIs and antacids may provide temporary relief but exacerbate the root cause by further suppressing acid production, leading to:<ul><li>&nbsp;Increased bacterial overgrowth (SIBO, H. pylori).</li><li>&nbsp;More bloating, indigestion, and nutrient deficiencies.</li><li>&nbsp;Chronic inflammation and systemic health decline.</li></ul><h3>Conclusion: It All Comes Back to the Gut</h3>The body thrives on proper digestion, nutrient absorption, and microbial balance—all of which depend on healthy stomach acid levels. Addressing low stomach acid can help resolve GERD, SIBO, and bloating while improving systemic conditions like autoimmune disorders, fatigue, skin issues, and hormonal imbalances.By optimizing stomach acid, we lay the foundation for better digestive health, immunity, and overall well-being.
