Distended stomach and discomfort. but no pain?

Possible overgrowth: Oftentimes, stomach distension and discomfort can complicate a history of irritable bowel syndrome. The cause is often that of small intestinal bacterial overgrowth (SIBO). This is tested for with the lactulose breath hydrogen test, and can often be treated with an antibiotic. Another reason could be a condition called gastroparesis, or poor stomach emptying, which benefits from other drugs.

?gas: Bloating of the abdomen is usually due to gaseous accumulation although fluid build-up or enlarged organs or aortic aneurysm can cause abdominal distension. To relieve gaseous distension drink hot water and apply a hot water bottle to the abdomen which helps break down gas build-up and enables you to pass it. Taking simethicone after meals prevents the gas build-up. See your Physician as needed.
