Endometrial polyps generally manifest clinically with a shorter menstrual cycle, usually occurring every 20 days or so, and a longer period, typically lasting 8 to 10 days or more before it ends. This is a typical clinical presentation of endometrial polyps, and there is usually no pain in the lower abdomen. However, if there is frequent bleeding and the bleeding lasts for a long time, causing endometrial inflammation, pain in the lower abdomen may occur. If the endometrial polyps are not inflamed, there will be no pain in the lower abdomen. If endometrial polyps are detected, the treatment generally involves performing a polypectomy under hysteroscopy within three to seven days after the end of the menstrual period, followed by anti-inflammatory treatment as appropriate. With simple endometrial polyps, there is no pain in the lower abdomen.
