    Abdomen - swollen

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

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


    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.

    When to Contact a Medical Professional

    Call your health care provider if:

    • The abdominal swelling is getting worse and does not go away
    • The swelling occurs with other unexplained symptoms
    • Your abdomen is tender to the touch
    • You have a high fever
    • You have severe diarrhea or bloody stools
    • You are unable to eat or drink for more than 6 - 8 hours

    What to Expect at Your Office Visit

    Your health care provider will perform a physical exam and ask questions about your medical history, such as:

    • Time pattern
      • When did the abdominal swelling begin?
      • Does it occur after meals or after eating certain foods?
    • What other symptoms occur at the same time? For example, have you had:
      • Absent menstrual period
      • Diarrhea
      • Excessive fatigue
      • Excessive gas or belching
      • Irritability
      • Vomiting
      • Weight gain

    Tests that may be done include:

    • Abdominal CT scan
    • Abdominal ultrasound
    • Blood tests
    • Colonoscopy
    • Esophagogastroduodenoscopy (EGD)
    • Paracentesis
    • Sigmoidoscopy
    • Stool analysis
    • X-rays of the abdomen
