The dangers of an enlarged uterus may lead to secondary anemia, dysmenorrhea, and infertility if the enlarged uterus is caused by adenomyosis or fibroids. The uterus of a fertile woman is about 7-8 cm long, 4-5 cm wide, 2-3 cm thick, has a capacity of about 5 ml, and weighs about 50-70 grams. If it exceeds this range, it is considered an enlarged uterus. If a woman simply has an enlarged uterus, and an ultrasound is done to make sure there are no fibroids or adenomyosis, the effect on the body is relatively minor. If the endometrial area of the uterus is significantly enlarged due to adenomyosis or uterine fibroids, this will lead to an increase in vaginal discharge and menstrual flow, and secondary anemia may occur over time. If the uterus is large as a result of adenomyosis or fibroids, it needs to be treated under medical supervision.
