How long it takes to have a period after hysteroscopic surgery depends mainly on the patient’s condition, the procedure and previous menstrual cycles. The onset of menstruation is due to the withdrawal of estrogen and progesterone from the body and the shedding of the uterine lining. Hysteroscopy basically does not affect estrogen and progesterone secretion in the body, so in the absence of damage to the endometrium from the surgery, normal menstruation will generally not be affected. Patients who have had regular periods in the past can project when their periods are due and will have their periods according to their usual normal cycle. However, some patients are more sensitive to the procedure and may have a slight menstrual disorder after surgery, but basically they will have their normal periods within 40 days as well. However, if the endometrium was removed during the hysteroscopic surgery, the patient needs to take oral estrogen and progestin therapy after the surgery and wait until the endometrium returns to normal and withdrawal bleeding occurs after stopping the medication before menstruation can be considered. After hysteroscopy, patients need to take rest, avoid overexertion, take regular rest and rest, and prohibit sexual intercourse for 1 month; at the same time, they need to strengthen hygiene care, keep the vulva clean, prevent infection, and prohibit tub bath or sitz bath for a short period of time, and can take a shower.
