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
- Premenstrual syndrome (PMS)
- Uterine fibroids
- Weight gain
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.
