During digestion, gas is a common occurrence in the digestive system. Burping and flatus are two natural ways to get rid of excess gas. Gas pain suggests that gas has been stuck or is not adequately moving through your digestive system.

After eating items that are more likely to produce gas, you may experience an increase in gas or gas pain. Changing one’s eating habits often leads to a substantial reduction in the quantity of gas produced.

An increase in stomach acid or gas pain may occur in addition to the many signs and symptoms associated with digestive system diseases such as irritable bowel syndrome or celiac disease.

The presence of gas or gas pains may be accompanied by other symptoms such as burping, deep breath, abdominal discomfort, bloating, distention, cramping, or a knotted feeling in your stomach.

There are a number of factors that cause bloating and gas. Swallowing air while eating or drinking produces a significant amount of gas in the stomach. When you burp, the majority of the gas that has accumulated in your stomach is expelled from your body. Bacteria in the large intestine ferment carbohydrates that were not digested in the small intestine, causing bloating. As a result, gas is generated in your digestive system.Gas pain in chest can be felt because of stomach gas.

Gas may produce severe pain and make the whole stomach seem bloated and sensitive. This achy sensation may occasionally extend to the back, causing gas pain in the back. Bloating may also occur along with gas pain in the lower abdomen. Minor gastrointestinal problems, such as stomach infections, may sometimes cause severe gas pain.


Stomach gas is mostly caused by swallowing air while eating or drinking. When you burp, you release the bulk of your stomach gas.

Bacteria in your large intestine (colon) ferment carbohydrates that are not digested in your small intestine. This causes gas to develop in your colon. However, bacteria eat a portion of the gas, and the remaining escapes via your anus.

Certain fiber-rich foods may also cause gas. Following are the foods that cause gas: 

·         Vegetables and fruits

·         Beans

·         Peas

·         Legumes

·         Whole grain i.e. grain that has not been treated

While high-fiber meals may cause gas, fiber is essential for maintaining a healthy digestive tract as well as regulating blood sugar and cholesterol levels.

Other food items that also lead to increased gas production include carbonated drinks like beer and soda; sugar substitutes like artificial sweeteners and fiber supplements. All these variables are responsible for excess colon gas. 

Certain conditions or medical illnesses are also responsible for the trapped gas in the stomach along with causing bloating and other gas-related discomforts. Some of these conditions include:

·         Irritable bowel syndrome or IBS

·         Ulcerative colitis

·         Crohn’s disease

·         Constipation

Infection: The colonization of the small intestine by bacteria also leads to increased gas production. It is possible that an increase or a shift in the bacteria in the small intestine will result in excessive gas, diarrhea, and weight loss.

Food intolerance: It is characterized by the inability of a person to eat specific foods. If your digestive system is unable to handle and absorb certain meals, such as the sugar found in dairy products (lactose) or the proteins found in wheat and other grains, such as gluten, you may have gas or bloating.

Dietary changes may help reduce the amount of gas produced by your body or increase the pace at which gas travels through your system. Keeping a food diary to monitor your diet and gas symptoms may help you and your doctor determine the most effective dietary changes. It is likely that you will have to avoid some meals or eat them in moderation.

When to see a doctor

Consult your doctor if your stomach pains are so persistent or severe that they interfere with your ability to function properly in daily life. Gas or gas pains that occur with other signs or symptoms may signal a more serious issue. Contact your doctor if you have a lot of gas and cannot poop. If you notice any of the following additional signs or symptoms, you need to see your doctor:

·         Stools with bloodstains

·         Altered stool texture

·         Constipation

·         Loss of weight

·        Consistent or recurring nausea and vomiting

·        Seek medical treatment on an immediate basis, if you have any of the following symptoms:

·         Abdominal discomfort that lasts for a long period

·         Aches and pains in the chest

·         Stomach pain and bloating
