Hysteroscopy is not harmful to the body, but it is usually performed to detect endometrial lesions, such as endometrial polyps, submucosal fibroids, and endometrial hyperplasia. During the hysteroscopy, the endometrial tissue may be scraped, or small polyps may be removed from the uterine cavity, after which there will be a small amount of vaginal bleeding. During this period, we should pay attention to keep the vulva clean and hygienic, wash the vulva with lukewarm water every day, and also pay attention to prohibit sexual intercourse and tub baths within one month after the hysteroscopy, and we should keep abreast of the pathology of the scraped tissues in the uterine cavity after the operation.
