What causes uterine atrophy?

The main causes of uterine atrophy include physiological atrophy (postmenopausal, lactation), pathological atrophy (uterine inflammation, surgery, other diseases) and iatrogenic factors (Radiotherapy, chemotherapy, long-term use of certain drugs). The main reasons for uterine atrophy include the following: 1. Physiological atrophy: Postmenopausal: Female menopause, ovarian function gradually decline, estrogen levels decline, leading to uterine gradual atrophy. Lactation: Lactation women, due to the role of prolactin, ovarian function is inhibited, estrogen levels are low, the uterus will shrink accordingly. 2. Pathological atrophy: Uterine inflammation: such as endometriosis, pelvic inflammatory disease, etc., can lead to myometrial damage, causing uterine atrophy. Uterine surgery: such as myomectomy, hysterectomy, etc., surgery will cause trauma to the uterus, causing uterine atrophy. Other diseases: premature ovarian failure, hypophysis, etc., can lead to decreased estrogen levels, causing uterine atrophy. 3. Iatrogenic factors: radiotherapy, chemotherapy: some cancer treatments may use radiotherapy, chemotherapy and other methods, these treatments may affect ovarian function, leading to uterine atrophy. Long-term use of certain drugs: antipsychotics, antidepressants, etc., may affect estrogen levels, leading to uterine atrophy. In short, the causes of uterine atrophy are more complex, may be physiological, may also be pathological, may also be related to iatrogenic factors. If uterine atrophy occurs, should seek medical attention in a timely manner, clear reasons, and take appropriate treatment measures.
