Swollen Abdomen

Also known as: distended abdomen, abdominal distention, distended stomach, bloated abdomen, bloated stomach

What is a swollen abdomen?

When the area of the body around the stomach is bloated or larger than it usually is, this is the sign of a swollen abdomen (or abdominal distenstion). Causes can range from overeating to more serious medical conditions.

What might cause swollen abdomen?

If the abdomen is swollen after a large meal, it can be from overeating.  Other medical causes may include:

• Intestinal gas from eating high-fiber foods
• Swallowing air
• Lactose intolerance
• Irritable bowel syndrome
• Weight gain
• Pregnancy
• Bowel blockage
• Premenstrual syndrome (PMS)
• Fluid buildup
• Ovarian cyst
• Uterine fibroids
• Abnormal growth of cells
• Celiac disease
• Infections

How can it be treated?

For some cases of swollen abdomen, the following approaches can help:

• Avoid carbonated beverages
• Avoid foods known to cause gas like beans and cauliflower
• Don’t chew gum (causes you to swallow extra air)
• Don’t use drinking straws
• Steer clear of lactose containing dairy products
• Eat more slowly

When should you seek medical attention?

If a swollen abdomen does not appear to be related to your diet, is growing worse or not improving, is tender or is accompanied by a high fever, diarrhea or bloody stools, talk to your health care provider.
