Hysteroscopy is a minimally invasive procedure that is somewhat invasive, so there will be some painful reactions. The length of the hysteroscopy depends on the specific purpose of the procedure, which may take only a few minutes for shorter procedures or about an hour for more complex ones. Hysteroscopy is both diagnostic and therapeutic, so the length of the hysteroscopy depends on whether other treatments are needed. If the hysteroscopy is used only for the definitive diagnosis of the disease, it often takes 10-20 minutes, or in more successful cases, a few minutes. If the examination is accompanied by other procedures such as separation of uterine adhesions, submucosal myomectomy, endometrial polypectomy, etc., the treatment time will be extended according to the length of the procedure, often in the range of 0.5-1 hour. There are some precautions to be taken before and after the hysteroscopy, such as ensuring sleep, prohibiting intercourse, relaxing and avoiding late nights before the procedure, and looking at this examination in a good frame of mind to facilitate the successful completion of the hysteroscopy. In the postoperative period, when accompanied by family members or under the supervision of medical staff, appropriate exercise can be performed, which is conducive to postoperative recovery and to reduce the occurrence of postoperative complications. If complications have arisen, contact your doctor for prompt management.
