The enlarged belly is not necessarily a gynecological disease, because if there is fat deposition, it will be deposited in the lower abdomen first, so the lower abdomen tends to become enlarged. If the enlarged belly is accompanied by menstrual disorders, such as amenorrhea or irregular vaginal bleeding, and lower abdominal swelling, you can go to the hospital for an internal gynecological examination or an ultrasound of the uterine adnexa to rule out the presence of fibroids or ovarian cysts causing the enlarged lower abdomen. If the lower abdomen is simply bigger and there is no change in menstruation, it is generally considered to be caused by fat deposits and is not a gynecological disease.
