Endometrial hyperplasia is categorized into endometrial hyperplasia with atypical hyperplasia and endometrial hyperplasia without endometrial atypical hyperplasia. Endometrial hyperplasia with atypical hyperplasia is relatively more serious, and if not treated in time, it will develop into endometrial cancer. Endometrial hyperplasia without atypical hyperplasia is relatively less serious, and can be reversed by taking medication orally or by placing a Mannix ring in the uterine cavity to counteract the increased secretion of estrogen, which causes overgrowth of the uterine lining. For endometrial hyperplasia with atypical hyperplasia, hysterectomy may be recommended if the patient is old enough not to have children, and regular checkups may be needed after the surgery.
