Hysteroscopic surgery is a minimally invasive procedure widely used in gynecology. It allows observation of the cervical canal, the endometrium, the endometrium and the opening of the fallopian tubes under direct vision, examination and diagnosis of the physiological and pathological conditions in the uterine cavity, and also allows surgical treatment in the uterine cavity under direct vision. After hysteroscopic surgery, proper rest, complete bed rest is not necessary, but avoid straining. Sexual intercourse, tub bathing and swimming are prohibited for two weeks after surgery. There may be a small amount of vaginal bleeding for a few days after surgery, and the length of bleeding varies slightly depending on the type of surgery. Antibiotics will be given at the doctor’s discretion to prevent infection and reduce the risk of reproductive tract infection. If there is significant abdominal pain or bleeding more than menstrual flow after the procedure, you need to seek medical consultation. Hysteroscopic surgery usually involves scraping the endometrium or removing endometrial polyps, which may damage the endometrium to a certain extent, but it does not affect ovarian function and usually results in menstruation one month after the surgery, or it may be delayed if the individual patient is nervous or stressed. Given that hysteroscopic surgery is a treatment that targets abnormalities in the uterus for examination and surgery and does not affect the endocrine function of the ovaries, menstruation usually resumes about 1 month after surgery.
