Can gas in the intestines cause abdominal pain?

Under normal circumstances, whether gas in the intestines causes abdominal pain depends on specific conditions. The detailed analysis is as follows:

When there is only a small amount of gas in the intestines and it can be expelled normally through intestinal peristalsis, abdominal pain usually does not occur. Under normal conditions, the human intestine continuously produces a small amount of gas, which can be released via flatulence or passed out with stool. In such cases, pressure within the intestines remains stable, causing no significant stimulation to the intestinal wall, and the body does not experience discomfort.

However, when there is excessive gas in the intestines, its expulsion is obstructed, or it accumulates in narrowed sections of the intestine, abdominal pain is more likely to occur. If gas buildup results from consuming too many gas-producing foods, swallowing excess air, or slowed intestinal motility, the increased pressure inside the intestines can stretch the nerves in the intestinal wall, leading to bloating and abdominal pain. The location of the pain often corresponds to where the gas has accumulated, and may be accompanied by symptoms such as bloating and difficulty passing gas.

In daily life, attention should be paid to dietary adjustments—reducing intake of gas-producing foods such as beans and onions, and avoiding overeating. Chew food thoroughly and eat slowly to minimize air swallowing. If bloating and abdominal pain occur frequently, engaging in light physical activities like walking may help enhance intestinal motility and facilitate gas release. If abdominal pain progressively worsens, or is accompanied by vomiting or cessation of flatus and bowel movements, prompt medical evaluation is necessary to rule out abnormalities such as intestinal obstruction.
