How to STOP Farting & Bloating for Good (Do This!)
In a Nutshell
Low stomach acid is the main root cause of gas and bloating because it impairs protein breakdown, allows bacterial overgrowth in the small intestine (SIBO), and blocks proper bile release. The solution involves fixing stomach acid with betaine HCl, eliminating trigger foods like fiber, sugar, grains, and dairy, and using intermittent fasting to activate the migrating motor complex for gut cleaning. Stress management through vagus nerve support and avoiding unnecessary antibiotics further prevents recurrence.

The volume of gas, the smell of farts, morning-to-evening stomach changes, and post-meal bloating each have different root causes and different solutions. 99% of gas generated in the body or taken in is non-odorous. Only 1% has a smell, which usually involves sulfur.
The stomach should be extremely acidic with a pH between 1 and 3. The stomach breaks down proteins to release locked nutrients such as zinc and B12. The high acidity also kills microbes, as very few can survive a pH of 1-3 (comparable to battery acid). Low stomach acidity is one of the most common root causes of gas and bloating.
Few bacteria live in the stomach. The small intestine has a moderate increase in bacteria. The large intestine contains the highest number of microbes, where fermentation occurs and generates the great majority of gas. When microbes ferment in the wrong location (small intestine instead of large intestine), this is called small intestinal bacterial overgrowth (SIBO).
SIBO creates problems because fermentation occurs in the small intestine. E. coli is friendly in the correct environment but creates issues when displaced. Foods that worsen SIBO include fiber and probiotics. Consuming salad, fiber, or probiotics can increase bloating when SIBO is present.
Small intestinal fungal overgrowth (SIFO) involves candida and other fungi/yeast that thrive on sugar and starches. Eliminating sugar and starches starves these organisms. People with SIBO or SIFO often experience inflammation, pain, and bloating. The carnivore diet frequently reduces these symptoms by starving microbes in the small intestine and reducing irritants to the large intestine.
SIBO-related bloating and gas are often triggered by beans, legumes, cruciferous vegetables (cabbage, broccoli, Brussels sprouts), dairy (due to allergies or lactose feeding microbes), and fruit (due to fructose). Fermentation occurs when microbes receive resources they cannot handle or when enzymes are missing to break down sugars, fibers, or starches. Sugar alcohols in ketogenic diet products (cookies, candies, cakes) cause gas and bloating because microbes ferment them. Grains, wheat, and gluten are major culprits; gluten is the only protein the body cannot digest, creating inflammation, stress, and gas. Onion and garlic are high in sulfur and create smelly gas.
When stomach acid is insufficient, proteins are not broken down to amino acids. The small intestine attempts to compensate, leading to putrefaction. Certain amino acids in meat contain sulfur, producing foul-smelling gas. The root issue is low stomach acid, not the protein itself. The solution is to re-acidify the stomach using betaine hydrochloride. If betaine hydrochloride causes burning, gastritis or an ulcer may be present; in ulcer cases, do not use it. Zinc carnosine is recommended for ulcer treatment.
Proton pump inhibitors (PPIs) and antacids should be used short-term only (maximum 8 weeks per guidelines) but are often taken lifelong, leading to complications. Antibiotics kill both good and bad microbes while allowing fungal overgrowth, compromising the digestive system. Stress inhibits stomach acid production. Junk food contributes to deficiencies in zinc, sodium, potassium, and B12, impairing acid production.
Stomach acid triggers bile release. Bile, produced by the liver and stored in the gallbladder, breaks down fats in the small intestine and acts as an antimicrobial to keep bacterial counts low and prevent SIBO. Bile is recycled after the final 20-25 feet of the small intestine. Because bile is alkaline, it can dilute stomach acid. Some bile salt supplements include betaine hydrochloride to counter this. If bile salts or ox bile worsen symptoms, acidify the stomach first before adding bile support. Fixing stomach acid often allows bile to naturally clean the small intestine.
Test foods one at a time with other foods to identify which cause bloating, then eliminate triggers individually. The body operates on signals including insulin, cortisol, inflammation, sleep quality, and gut function; fixing the most broken signal is essential.
The natural cleaning process called the migrating motor complex (MMC) does not function during eating or snacking. Intermittent fasting and stopping snacking allow the MMC cleaning wave to push material out of the system, which also helps release more bile.
Bloating that develops throughout the day despite a flat stomach in the morning is often stress-related rather than food-related. Stress activates the sympathetic (fight-or-flight) nervous system and suppresses the parasympathetic (rest-and-digest) system via the vagus nerve. Long walks, nose breathing (slowly, not chest breathing), quality sleep, and vitamin B1 support vagus nerve function and reduce this type of bloating. Vitamin B1 deficiency is common in diabetes and contributes to neurological, vagus nerve, and digestive issues including constipation.
Antibiotics for SIBO have a high recurrence rate (44%) because they kill both good and bad bacteria, allowing certain organisms to overgrow in the altered environment. Antibiotics should be used only when absolutely necessary. L. reuteri is a keystone microbe that suppresses bad bacteria in the small intestine and increases oxytocin, providing powerful anti-stress effects. L. reuteri can be cultured into yogurt for daily consumption.
