There are many aspects to the causes of lower abdominal distension in women, but for women, gynaecological and digestive disorders are the main considerations. Gynecological diseases such as fibroids, adnexitis, pelvic inflammatory disease and ovarian cysts can cause lower abdominal distension and pain, which is often accompanied by irregular menstruation. Digestive tract disorders such as functional indigestion, appendicitis and intestinal obstruction are common.
Women are usually advised to visit a gastroenterologist or gynaecologist to identify the specific disease through further investigations.
