What is Intestinal Gas?
Intestinal gas is a normal part of digestion. Gas enters the digestive tract when you swallow air and when bacteria in the large intestine break down undigested food.
Gas Passage
Gas can leave the body in two main ways: by belching through the mouth or by passing gas (flatus) through the rectum. Passing gas several times a day can be normal.
Symptoms
Common symptoms include belching, bloating, abdominal distention, and passing gas. Gas may become a problem when these symptoms happen often, cause pain, or interfere with daily life.
Management
Treatment depends on the cause of the gas. Doctors may recommend changes in eating habits, diet, or medicines and supplements to reduce symptoms.
- Exogenous Gas
Exogenous gas means gas that comes from outside the body, usually from swallowing air. This may improve by eating more slowly, avoiding chewing gum, reducing fizzy drinks, and limiting habits that cause extra air swallowing. - Endogenous Gas
Endogenous gas is gas made inside the intestines, mainly when bacteria break down certain foods that are not fully digested. Management may include identifying food triggers, adjusting the diet, and treating any underlying digestive problem if present.
Outlook
The outlook is generally good. In many people, intestinal gas improves with simple diet and lifestyle changes, but persistent or severe symptoms may need medical assessment to rule out another digestive condition.
