Uterine hypertrophy may be related to chronic uterine insufficiency in multiple births, ovarian dysfunction, inflammation and other causes. 1. Chronic uterine recuperation insufficiency in multigravid women: in these patients, the elastic fibrous tissue of the myometrium proliferates between the smooth muscles and around the blood vessels, resulting in the phenomenon of uterine hypertrophy. 2. Ovarian dysfunction: symptoms of abnormal estrogen secretion may occur, and the myometrium can be hypertrophied due to the continuous stimulation of estrogen. 3. Inflammation: chronic adnexitis, pelvic connective tissue inflammation, chronic myositis of the uterus and other diseases are common. The stimulation of inflammation can cause collagen fiber proliferation in the myometrium, resulting in this condition. In addition, uterine hypertrophy can also be seen in other diseases. It is recommended that patients go to the hospital for relevant examinations in a timely manner, and follow the doctor’s instructions for treatment, so as not to delay the condition.
