Endometrial hyperplasia, or endometrial hyperplasia, is a non-physiological, non-invasive abnormal proliferation of the endometrium due to long-term estrogen stimulation without progesterone antagonism. It occurs in perimenopausal and postmenopausal women and is characterized by abnormal uterine bleeding, scanty menstruation and even infertility. The severity of endometrial hyperplasia can be determined by the severity of the patient’s symptoms and the type of endometrial hyperplasia.1. No atypical hyperplasia: refers to excessive hyperplasia of endometrial glands with irregular size and shape, but not accompanied by cellular atypia. It includes simple hyperplasia and complex hyperplasia. The chance of endometrial cancer is relatively small and the severity is not great. For patients without atypical hyperplasia, drug therapy should be preferred. It is recommended to use drugs such as kynurenine tablets and progesterone according to medical prescriptions, and you can also choose to place intrauterine Mannakia ring, which acts locally on the endometrium; 2. Atypical hyperplasia: refers to excessive hyperplasia of endometrial glands with cellular atypia, which has a higher risk of endometrial cancer and is a precancerous lesion, compared with those without atypical hyperplasia. It is more serious. For patients with atypical hyperplasia, surgery should be the first choice under the advice of a physician, and total hysterectomy is recommended, provided that they do not have fertility requirements. Patients with fertility requirements can choose to take oral medication or place the Manned Ring and have their endometrial pathology reviewed regularly at three months. After the endometrium has returned to normal, conception can be guided under strict follow-up conditions. When patients have abnormal menstruation or abnormal vaginal bleeding or post-menopausal vaginal bleeding, it is recommended to visit the gynecologist in time. The doctor will perform appropriate gynecological examination, imaging and laboratory tests according to the characteristics of the patient’s symptoms. Patients who are diagnosed with endometrial hyperplasia need to follow the doctor’s instructions for active treatment and regular review, as well as to develop good lifestyle habits and increase physical exercise.
