What are some causes of abdomen distension in women?

Causes of abdomen distension in women include pregnancy, overeating, gas or medical conditions such as irritable bowel syndrome, or an intolerance to lactose, explains Healthline. A distended abdomen is also caused by indigestion, heartburn, weight gain and a hormonal flux.

Some medications can cause a distended abdomen in women as well as intestinal parasites, an overgrowth of small bowel bacteria, constipation and an inflammatory bowel disease, according to Healthline. Less common causes of a distended abdomen include pancreatitis, an intestinal blockage or gallstones. A distended stomach that leaves women feeling bloated can cause tightness and swelling in the abdomen in addition to a feeling of fullness, pain, frequent belching and excessive gas.
