Uterine polyps are common gynecological diseases. Clinically, they are usually referred to as endometrial polyps, which are benign lesions of the endometrium that protrude from the surface of the endometrium and occur in women of childbearing age and menopause, and their prevalence has increased among women of childbearing age. Uterine polyps can be single or multiple, 1/3 of patients do not have any obvious symptoms, only found during physical examination; those with symptoms are mainly irregular vaginal bleeding and infertility. 1.Uterine polyps can be found at any age: but they are common in women over 35 years old, the main symptom is irregular vaginal bleeding, some patients can see irregular menstruation, excessive menstruation or prolonged menstruation or bleeding after menopause. The polyp may protrude from the cervical opening and cause secondary infection or polyp necrosis, thus causing irregular bleeding; the vaginal bleeding will be aggravated and increased after stress or exertion, there will also be bloody discharge with bad odor, abdominal pain in the second half of menstruation and progressive aggravation; a few patients with large polyps will have increased leucorrhea, or leucorrhea with blood. 2.Patients with uterine polyps may also experience infertility: when the polyps are large, they can occupy the uterine cavity and affect the contraction of the uterus; abnormal uterine bleeding can affect the fertilization of the egg and its development; polyps located in front of the cervical canal and fallopian tube mouth can affect the passage of sperm, as they affect the upward movement of sperm, resulting in the inability of sperm to meet the egg in the fallopian tube to form a fertilized egg, thus leading to infertility. 3, cancer: when the polyp is large, or the patient has high blood pressure or long-term chronic inflammatory stimulation, can lead to polyp malignancy, and with age, the malignant rate will be higher and higher; asymptomatic, the diameter of the uterine polyps <1cm patients cancer rate is very low. To sum up, the symptoms of uterine polyps are mainly irregular vaginal bleeding, infertility, postmenopausal bleeding, and endometrial thickening can be seen on examination.
