You're sitting in a quiet meeting or maybe trying to enjoy a first date, and then it happens. That familiar, rolling pressure builds up in your chest, and a second later, you're fighting back a loud, unprompted belch. It’s annoying. When it happens once or twice, you blame the soda. But when it becomes a daily cycle of constant burping and stomach discomfort, it starts to feel like your digestive system has staged a coup. Honestly, most people just assume they have "too much acid" and start popping Tums like candy, but the reality is usually way more nuanced than that.
Burping is just gas escaping. Simple, right? Not really. When it's chronic, it’s usually a sign that the delicate balance of pressure, enzymes, and bacteria in your gut has gone sideways.
The Air You’re Actually Swallowing
Most people are surprised to learn that a huge chunk of "stomach gas" isn't actually produced in the stomach. It’s swallowed. Doctors call this aerophagia. You might be doing it without even realizing it. Talking while eating? Check. Drinking through a straw? Yep. Even just being chronically stressed can make you take short, shallow gulps of air.
When you swallow air, it collects in the esophagus or the upper part of the stomach. The body has one of two choices: send it down or send it back up. If your lower esophageal sphincter (the little muscular flap that acts as a gatekeeper) is a bit relaxed, that air is coming back up as a burp. But if it stays trapped, you get that heavy, bloated sensation in the upper abdomen.
Dr. Brennan Spiegel, a gastroenterologist and author of Hurry Up and Wait, has spent years looking at how our brains and guts talk to each other. He often points out that bloating and gas aren’t just physical "bubbles" but a complex interaction of visceral hypersensitivity. Basically, your gut might feel like it's exploding even if the actual volume of gas is normal. Your nerves are just on high alert.
When the Stomach Acid Myth Trips You Up
We’ve been conditioned to believe that heartburn and burping always mean high stomach acid. Because of this, millions of people take Proton Pump Inhibitors (PPIs) like Prilosec or Nexium. But here is the kicker: low stomach acid (hypochlorhydria) can actually cause the exact same symptoms.
Think about it this way. If you don't have enough acid to break down your food, that food just sits there. It starts to ferment. Bacteria in your gut have a field day with those undigested particles, and the byproduct of that feast is—you guessed it—gas. This creates a cycle of constant burping and stomach discomfort because the stomach is struggling to empty itself.

There's also a condition called Gastroparesis. It's basically "lazy stomach." The muscles don't move food along as fast as they should. This is common in people with diabetes or those who have had certain viral infections. If the food stays in the stomach for four hours instead of two, you're going to feel like a balloon.
The Role of SIBO and the "Internal Brewery"
If the burping is accompanied by intense bloating that makes you look six months pregnant by the end of the day, you might want to look into SIBO. That stands for Small Intestinal Bacterial Overgrowth.
Normally, most of your gut bacteria should live in your large intestine (the colon). In SIBO, these bacteria migrate up into the small intestine where they don't belong. When you eat carbs or sugar, these bacteria ferment the food way too early in the digestive process. This happens high up in the GI tract, leading to gas that has nowhere to go but up.
It’s messy. It’s uncomfortable. And it often leads to a "brain fog" feeling because of the metabolites these bacteria produce. Researchers at Cedars-Sinai, led by Dr. Mark Pimentel, have found that a significant portion of people diagnosed with Irritable Bowel Syndrome (IBS) actually have SIBO.
Common Triggers You Might Be Ignoring
- FODMAPs: These are specific types of fermentable sugars found in everything from garlic and onions to apples and wheat. Some people just can't process them.
- Artificial Sweeteners: Sorbitol and xylitol are famous for causing gas. They are found in "sugar-free" gums and keto snacks.
- Carbonation: This is obvious, but it’s not just soda. Sparkling water is a major culprit for constant burping.
- Rapid Eating: If you finish a meal in five minutes, you're gulping air. Period.
H. Pylori: The Uninvited Guest
Sometimes the cause is an actual infection. Helicobacter pylori (H. pylori) is a bacteria that burrows into the stomach lining. It’s incredibly common—roughly half the world's population has it—but for some, it causes chronic gastritis.
H. pylori survives the harsh acid of the stomach by producing an enzyme called urease. This enzyme neutralizes stomach acid and produces carbon dioxide as a byproduct. That CO2 has to go somewhere. If you have constant burping and stomach discomfort along with a dull, gnawing ache when your stomach is empty, it’s worth asking your doctor for a simple breath or stool test. It’s treatable with antibiotics, and getting rid of it can sometimes stop the burping overnight.

Why "Supragastric" Burping is Different
There is a weird phenomenon called supragastric burping. This isn't gas coming from the stomach at all. Instead, it's a behavioral pattern where a person sucks air into the esophagus and immediately pushes it back out.
It often happens subconsciously as a response to some other abdominal discomfort. You feel a "twinge," you burp to try and relieve the pressure, and it becomes a tic. The problem is that the more you do it, the more you irritate the esophagus, which creates more discomfort, leading to more burping. It’s a vicious loop. Behavioral therapy or even speech therapy can actually help "retrain" the throat muscles to stop this.
Is it Your Gallbladder?
Don't overlook the gallbladder. This tiny organ stores bile, which helps you digest fats. If you have gallstones or if your gallbladder is just "sluggish" (biliary dyskinesia), you might struggle to process greasy meals.
This usually feels like a sharp or heavy pain in the upper right side of your abdomen, often radiating to your shoulder blade. But before the sharp pain starts, many people experience months of constant burping and stomach discomfort after eating fatty foods. If fried chicken makes you feel like you've swallowed a bowling ball, your gallbladder might be the "who" in this whodunit.
What You Can Actually Do About It
First, stop the "emergency" fixes. Overusing antacids can sometimes make the problem worse in the long run by suppressing the acid you actually need for digestion.
Instead, try the "Low and Slow" approach.

Eat smaller meals. Chew your food until it’s basically liquid. This reduces the work your stomach has to do and minimizes the air you swallow.
If you suspect SIBO or FODMAP sensitivity, try an elimination diet, but do it under the guidance of a dietitian. Cutting out entire food groups blindly can lead to nutritional deficiencies.
Keep a "burp diary." Sounds gross, I know. But tracking what you ate before the episodes start can reveal patterns you’d never notice otherwise. Is it always after your morning latte? Is it only when you're stressed at work?
Actionable Steps for Relief:
- Test, Don't Guess: Ask your doctor for an H. pylori breath test and a SIBO breath test if symptoms persist for more than a few weeks.
- The 30-Chew Rule: Try to chew every bite of food 30 times. It sounds excessive, but it forces you to eat slower and prevents air swallowing.
- Check Your Meds: Some medications, like NSAIDs (Ibuprofen/Advil), can irritate the stomach lining and cause gastritis, leading to gas.
- Try Ginger or Peppermint: Real ginger tea can help speed up gastric emptying, meaning food doesn't sit and ferment as long. Peppermint oil capsules can relax the digestive tract, though be careful—they can sometimes trigger reflux in people with a weak lower esophageal sphincter.
- Post-Meal Movement: A 10-minute walk after eating helps stimulate "peristalsis," the wave-like muscle contractions that move food and gas through your system.
Constant burping and stomach discomfort aren't usually a medical emergency, but they are a loud signal from your body that something is out of sync. Whether it's the way you're breathing, the balance of bacteria in your small intestine, or just a hidden sensitivity to your favorite hot sauce, paying attention to the pattern is the only way to get some peace and quiet.
If you start experiencing "red flag" symptoms like unexplained weight loss, difficulty swallowing, or severe pain that wakes you up at night, skip the home remedies and get to a specialist immediately. For everyone else, it’s usually a matter of slowing down, checking the gut microbiome, and realizing that your stomach is a lot more sensitive to your lifestyle than you think.
