Abdomen, swollen

Alternative names:

abdominal distention; distended abdomen; swelling in the abdomen; swollen belly

Definition:

Increased abdominal girth.

Considerations:

Abdominal distention is usually not caused by disease. For example, simple weight gain, premenstrual syndrome (PMS), pregnancy, or the unconscious swallowing of air can all cause distention.

Abdominal distention commonly results from intestinal gas. This may result from eating fruits, vegetables, or nonabsorbable foods.

Abdominal distention may occasionally result from the accumulation of fluid in the abdomen.

Common causes:

• overeating
• lactose intolerance
• air swallowing (a nervous habit)
• irritable bowel syndrome
• partial bowel obstruction
