Endometrial polyps can be self-healing, and self-healing occurs mainly in the following two special cases: First, endometrial polyps in women of childbearing age are solitary, less than 1cm, and are discharged as the patient’s uterine lining is stripped off. Mainly because the endometrial polyp has a very thin tip, when there is a large piece of endometrial exfoliation, the polyp will be discharged along with the exfoliated endometrium. Secondly, in peri-menopausal women, the ovaries decline, estrogen and progesterone levels decrease, and the uterus and the endometrium will gradually shrink, endometrial polyps will also gradually shrink, and endometrial polyps can disappear on their own. In women of childbearing age with normal estrogen and progesterone levels, multiple endometrial polyps or single endometrial polyps that are relatively large are difficult to cure and need to be treated.
