Common Causes:

Abdominal swelling, or distention, is more often caused by overeating than by a serious illness. This problem can be caused by:

• Air swallowing (a nervous habit)
• Buildup of fluid in the abdomen (this can be a sign of a serious medical problem)
• Gas in the intestines from eating foods that are high in fiber (such as fruits and vegetables)
• Irritable bowel syndrome
• Lactose intolerance
• Ovarian cyst
• Partial bowel blockage
• Pregnancy
• Premenstrual syndrome (PMS)
• Uterine fibroids
• Weight gain

Home Care:

A swollen abdomen that is caused by eating a heavy meal will go away when you digest the food. Eating in moderation will help prevent swelling.

For a swollen abdomen caused by swallowing air:

• Avoid carbonated beverages
• Avoid chewing gum or sucking on candies
• Avoid drinking through a straw or sipping the surface of a hot beverage
• Eat slowly

For a swollen abdomen caused by malabsorption, try changing your diet and limiting milk. Talk to your doctor.

For irritable bowel syndrome:

• Decrease emotional stress
• Increase dietary fiber
• Talk to your doctor

For a swollen abdomen due to other causes, follow prescribed therapy to treat the cause.
