Typical symptoms of chronic endometritis: First, pain in the pelvic region, painful lower abdominal cramps and lumbosacral soreness during the intermenstrual period, some patients may not have any conscious symptoms. Second, increased leucorrhea, due to increased secretion of endometrial glands, usually thin and watery, yellowish, sometimes bloody leucorrhea. In elderly endometritis, the leukorrhea is purulent and often contains a small amount of blood. When the uterus accumulates pus, the secretion is purulent with foul smell. Third, excessive menstruation, regular periods, while the volume of menstrual blood multiplies, the bleeding period is significantly prolonged, irregular bleeding is less common. Fourth, dysmenorrhea, mostly seen in unproductive women, but severe dysmenorrhea is rare, probably due to excessive thickening of the endometrium, which prevents normal tissue degeneration and necrosis and stimulates excessive spasmodic contraction of the uterus. Symptoms of acute endometritis include mild fever, lower abdominal pain, increased leucorrhea, sometimes bloody, and in the case of anaerobic bacterial infections may have a foul odor, and acute endometrial inflammation occurring after childbirth or abortion is more severe.
