A thick endometrium is amenable to curettage. When the endometrium is thick, there may be abnormal bleeding and increased menstrual flow, in which case ultrasound monitoring or hysteroscopic curettage may be performed. After the endometrium is removed, pathological tests can be performed. Depending on the results of the pathological tests, such as changes in the secretory phase or changes in the proliferative phase of the endometrium, the corresponding treatment can be performed. It is usually possible to regulate the normal menstrual cycle to avoid the recurrence of abnormal bleeding or increased menstrual flow. After endometrial curettage, it is also important to pay attention to personal hygiene to avoid cross-infection.
