Considerations:

Abdominal swelling, or distention, is a common condition, which usually results from over-eating, rather than from a serious illness. Simple weight gain, premenstrual syndrome (PMS), pregnancy, or the unconscious swallowing of air can lead to this problem.

Abdominal distention is often due to gas in the intestines. This may result from eating fibrous foods such as fruits and vegetables. Beans are common sources of intestinal gas. Dairy foods can lead to abdominal swelling if you are lactose intolerant.

Abdominal swelling may also occasionally result from the accumulation of fluid in the abdomen, which can be a sign of serious medical problems. There are usually other symptoms in this case.

Common Causes:

• Air swallowing (a nervous habit)
• Irritable bowel syndrome
• Lactose intolerance
• Ovarian cyst
• Overeating
• Partial bowel obstruction
• Uterine fibroids
