Hysteroscopy is a commonly used examination in obstetrics and gynecology, and is often used to examine the endometrial environment, to determine the opening of the fallopian tubes, and to diagnose and treat uterine space-occupying lesions. Bleeding for a few days after a hysteroscopy depends on whether or not treatment has been performed at the same time. If the hysteroscopy is simply performed without treatment, the bleeding in this case is relatively short and usually stops gradually in 2-3 days. Because there is less interference or damage to the uterine cavity and cervix, the bleeding time after the examination is shorter. If a polyp is found in the hysteroscopy and removed, the vaginal bleeding will usually be clean for about 5-6 days; if the uterine adhesion separation surgery is performed at the same time, the bleeding will usually take about 7 days; if the uterine submucous fibroid removal surgery is performed, the vaginal bleeding will take about 10 days. After hysteroscopy, prohibit sexual intercourse for 1 month and avoid catching cold, pay attention to strengthen rest, avoid excessive weight bearing, especially long-term bending; strengthen hygiene, prevent intrauterine infection, especially during bleeding, need to change sanitary napkins, with obvious discharge combined with medication cleaning, prohibit bathtubs or sitz baths, you can take a shower.
