You’re sitting at dinner. Everyone else is laughing, passing the bread, and enjoying their steak, but you’re just sitting there wondering if that first bite is going to trigger a "situation." It’s exhausting. Living with a gut that feels like a ticking time bomb isn’t just uncomfortable—it’s isolating. Honestly, most advice out there is garbage. People tell you to "eat more fiber" or "drink ginger tea," but if you have something like Small Intestinal Bacterial Overgrowth (SIBO), adding more fiber is basically like throwing gasoline on a fire.
If you want to know how to fix stomach problems, you have to stop treating your body like a math equation and start treating it like an ecosystem. It’s messy. It’s loud. And it’s incredibly specific to you. What works for your neighbor’s bloating might make your acid reflux ten times worse.

The Myth of the Universal Gut Diet
We’ve been sold this idea that there’s a "perfect" way to eat. There isn't. The Mediterranean diet is great for heart health, but if you have a histamine intolerance, all those tomatoes and aged cheeses are going to leave you covered in hives or clutching your stomach.
Doctors often default to the low-FODMAP diet. It stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. Basically, it’s a list of short-chain carbohydrates that the small intestine doesn't absorb well. When they sit there, they ferment. They off-gas. You bloat. While this diet is a godsend for IBS sufferers, it's meant to be a short-term elimination phase, not a lifestyle. I’ve seen people stay on it for years, which actually starves the good bacteria in the large intestine. You end up with a "sterile" gut that’s even more reactive than when you started.
Complexity is the reality here. Your microbiome contains trillions of microbes. Trillions. To think a single green juice is going to fix that balance is, frankly, a bit silly.
Why Your Brain is Actually Your Second Stomach
Have you ever had "butterflies" before a big presentation? Or felt nauseous after getting bad news? That’s the vagus nerve talking. It’s a physical highway connecting your brain to your digestive tract.
When you’re stressed, your body enters "fight or flight" mode. Digestion is a "rest and digest" function. If you’re constantly scrolling through stressful news or rushing between meetings, your body literally shuts down the blood flow to your gut. The enzymes don't secrete. The muscles that move food along—the migrating motor complex—just stop. Food sits there. It rots.
You can eat the cleanest, most organic diet on the planet, but if you’re eating it while standing up in a state of high cortisol, you’re going to have stomach issues. It’s physics. You have to stimulate the parasympathetic nervous system. Something as simple as three deep belly breaths before your first bite can do more for your digestion than a $60 bottle of probiotics. Seriously.
The Acid Reflux Paradox
Most people think heartburn is caused by too much stomach acid. They pop antacids like candy. Brands like Tums or Prilosec make billions off this assumption. But for a huge chunk of people, the problem is actually too little stomach acid, a condition called hypochloridria.
When you don’t have enough acid (HCl), your stomach can’t break down proteins properly. The food sits there too long, pressure builds up, and it forces the Lower Esophageal Sphincter (LES) open. That tiny bit of acid splashes up, and it burns. If you take an antacid for this, you’re just making the underlying problem—weak digestion—worse.

Dr. Jonathan Wright, a pioneer in nutritional medicine, has written extensively about how stomach acid production naturally declines as we age. By the time you're 60, you might be producing half the acid you did at 20. If you feel "heavy" for hours after eating meat, you might need more acid, not less.
Signs You Might Have Low Acid
- Bloating immediately after eating.
- Undigested food in your stool.
- Brittle fingernails (a sign you aren't absorbing minerals).
- Feeling full after just a few bites.
Stop Ignoring the "Moving" Part
Digestion isn't just chemical; it's mechanical. Your gut is a tube of muscle. In a healthy person, a "cleansing wave" happens every 90 to 120 minutes between meals. This is the Migrating Motor Complex (MMC). It’s like a janitor sweeping the hallways of your small intestine, pushing out bacteria and leftover food debris.
Snacking is the enemy of the MMC. Every time you eat—even a handful of almonds or a sip of a latte—the cleaning cycle stops. If you’re a "grazer" who eats every two hours, your gut never gets cleaned. This is a primary driver of SIBO. Bacteria from the large intestine migrate up into the small intestine because no one is there to sweep them back.
Space out your meals. Give yourself four hours between breakfast and lunch. Let your body do its housework.
The Supplement Trap
The supplement industry is a wild west. You see influencers swearing by "gut-healing" powders with 50 ingredients. Most of it is filler.
If you're serious about how to fix stomach problems, you have to be surgical with supplements. L-Glutamine can help "seal" a leaky gut, but only if the irritation source is gone. Probiotics are hit-or-miss. For some, they cause massive brain fog and bloating. Research from the Weizmann Institute of Science suggests that for many people, probiotics don't even colonize the gut—they just pass through.
Instead of a multi-strain probiotic, some people find better results with Saccharomyces boulardii. It’s actually a beneficial yeast, not a bacteria. It’s tough. It survives stomach acid. It’s particularly good at crowding out pathogens like C. diff or helping after a round of antibiotics.
Real-World Action Steps
Don't try to change everything tomorrow. You’ll fail and get frustrated. Pick one of these and stick to it for a week.
1. The 30-Chew Rule.
Your stomach doesn't have teeth. If you swallow chunks of food, your enzymes have to work ten times harder. Chew your food until it's a liquid paste. It sounds gross, but it's the single most effective free way to reduce gas.
2. Bitters Before Meals.
Gentian or dandelion root "bitters" stimulate the bitter receptors on your tongue. This sends a signal to your brain to start pumping out bile and stomach acid. It’s like a warm-up for your digestive system.
3. Test, Don't Guess.
If you’ve been struggling for years, stop buying random pills. Get a GI-MAP stool test or a breath test for SIBO. You might have a parasite, or an overgrowth of H. pylori, or a lack of certain beneficial species like Akkermansia. You can't fix what you haven't identified.
4. Movement After Eating.
A ten-minute walk after dinner isn't just for old people. It helps move food through the stomach (gastric emptying) and lowers the blood sugar spike associated with the meal. It’s a literal mechanical aid for your intestines.

The Bottom Line
Your gut is trying to tell you something. Pain, gas, and reflux are signals, not just annoyances to be muffled with medication. Fixing these issues usually requires a mix of slowing down, eating intentionally, and occasionally using targeted interventions to reset the bacterial balance. It takes time. Your gut lining replaces itself roughly every five days, but deep healing of the microbiome can take months. Be patient. Listen to the signals. Stop snacking every hour. And for heaven's sake, breathe before you eat.
