Whether endometrial polyps of 0.5-0.8 centimeters are serious or not depends on the specific situation. Endometrial polyps may be caused by inflammation of the endometrium, estrogen stimulation, etc., resulting in endometrial hyperplasia. If the diameter of the endometrial polyp is less than 1 centimeter and there are no other uncomfortable symptoms, most of the polyps can disappear through oral medication such as dextroprogesterone and progesterone, and the condition is not serious. If the endometrial polyp has increased menstrual flow, prolonged menstrual period, affecting the fertilization egg implantation and other symptoms, then the patient needs to be surgically removed, so endometrial polyp 0.5 ~ 0.8 cm is a more serious situation. Endometrial polyp patients usually need to pay attention to personal hygiene, so as not to cause infection and damage. Patients can also participate in more soothing sports, which is conducive to recovery. Endometrial polyps are categorized into single and multiple types, and the treatment of different types of diseases is also different, so it is recommended that patients consult a doctor under the guidance of timely consultation.
