Abdomen - swollen

Swollen belly; Swelling in the abdomen; Abdominal distention; Distended abdomen

 

A swollen abdomen is when your belly area is bigger than usual.

Causes

 

Abdominal swelling, or distention, is more often caused by overeating than by a serious illness. This problem also 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 smaller amounts 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 health care provider.
