Stomach gas, also called flatulence, is a common digestive health problem. According to MayoClinic.com, excess gas can result in passing gas through the rectum, increased belching and uncomfortable feelings of bloating. Abnormal amounts of gas can produce discomfort and pressure within the stomach and small intestine. As a result, pain often develops within the stomach and other digestive organs. Gas is usually expelled through the mouth or anus.
Swallowing Air
Swallowed air, also known as aerophagia, contributes to stomach gas. The International Foundation for Functional Gastrointestinal Disorders reports that air can be swallowed while smoking, chewing gum, eating food, wearing loose dentures or drinking liquids. The main causes of aerophagia are inadequate diet, carbonated beverages, symptoms of physical disease and stress. This condition is often treated by changing dietary and lifestyle changes.
Food
According to MayoClinic.com, certain foods can cause stomach gas. This includes common foods such as beans, cabbage, milk, carbonated drinks, bran, Brussels sprouts and broccoli. Foods rich in complex sugars or carbohydrates can result in stomach gas as the digestive system breaks it down. Patients with excessive gas from foods should consult a physician to construct a diet plan, receive medication or discuss a treatment plan.
Medical Conditions
MayoClinic.com notes that certain medical conditions such as pregnancy and irritable bowel movement can cause stomach gas. Lactose intolerance and celiac disease are other conditions that cause gas by preventing the stomach from absorbing digestive food components. According to the American College of Gastroenterology, certain prescription medications, such as antibiotics, can cause excessive stomach gas, especially those that inhibit digestive enzymes.
