Your digestive system produces gas as part of the regular digesting process. It’s also usual to expel extra gas, either by burping or passing gas (flatus). If gas is stuck in your digestive tract or is not passing through it efficiently, you may have gas discomfort.

Eating meals that are higher in gas production may cause an increase in gas or gas discomfort. Oftentimes, uncomfortable gas may be reduced with quite easy dietary adjustments.

Along with other symptoms, some digestive system problems, such celiac disease or irritable bowel syndrome, can increase gas or produce gas discomfort.


Indices or symptoms of stomach discomfort or gas include:


gas passing

Abdominal pain, cramps, or a knotted sensation

bloating, or a sensation of fullness or pressure in the belly

A noticeable enlargement of your abdomen (distention)

Burping is common, especially during or immediately following a meal. Up to twenty times a day, most individuals pass gas. Therefore, burping and passing gas are rarely indicators of a medical issue on their own, even if experiencing gas may be uncomfortable or unpleasant.

When to visit a physician

If your chronic or severe gas or gas pains are making it difficult for you to go about your everyday life normally, see your doctor. When gas or gas pains are combined with other symptoms or indicators, they may point to more serious illnesses. If you encounter any of the following extra indications or symptoms, consult your physician:

crimson stools

Modification in the stools’ consistency

Alteration in the regularity of bowel motions

Loss of weight

diarrhea or constipation

persistent or recurring vomiting or nausea

Seek prompt medical attention if you encounter:

persistent discomfort in the abdomen

chest ache


The main cause of gas in your stomach is air that you ingest when you eat or drink. Burping releases most of the gas in your stomach.

When bacteria ferment carbohydrates—fiber, certain starches, and some sugars—that aren’t broken down in your small intestine, gas is produced in your large intestine (colon). Some of the gas is also consumed by bacteria, but the remainder is expelled when you pass gas from your anus.

Typical meals that produce gas

Some foods high in fiber can make you gassy, such as:

Legumes: peas and beans



complete grains

Although eating a lot of fiber causes you to produce more gas, fiber is necessary to maintain a healthy digestive system as well as control blood sugar and cholesterol levels.

Other nutritional aspects

The following are additional food components that may also lead to a rise in gas in the digestive system:

Beer and soda are examples of carbonated drinks that make stomach gas worse.

More air is swallowed when eating when one eats too rapidly, drinks via a straw, chews gum, suckers on candy, or talks while chewing.

Colic gas may rise when taking psyllium-containing fiber supplements, such Metamucil.

Some sugar-free foods and beverages contain artificial sweeteners, such as sorbitol, mannitol, and xylitol, which can act as sugar replacements and result in excessive gas in the colon.

Health issues

The following illnesses have the potential to exacerbate intestinal gas, bloating, or gas pain:

intestinal illness that is persistent. A common indicator of long-term digestive disorders including diverticulitis, ulcerative colitis, or Crohn’s disease is excess gas.

bacterial overgrowth in the small intestine. Excessive gas, diarrhea, and weight loss may be brought on by an alteration or growth in the bacteria in the small intestine.

allergies to food. Your digestive system may not be able to properly break down and absorb some meals, such as the lactose sugar found in dairy products or the gluten protein found in wheat and other grains, which can cause gas or bloating.

diarrhea. Gastric distress can impede the passage of gas.
