Introduction
If the polyp diameter is less than 1 cm and the patient has no abnormal vaginal bleeding, menstrual irregularities, or other symptoms—especially in women of reproductive age—some polyps may regress spontaneously with hormonal changes, and surgery can be temporarily avoided. These polyps are often functional and can be monitored regularly via ultrasound. For example, small polyps formed due to hormonal fluctuations in adolescent or reproductive-age women may naturally regress during the menstrual cycle.
Generally, endometrial polyps larger than 1 cm in diameter often require surgical removal, although specific treatment should be determined based on symptoms, patient age, and fertility needs. If there are concerns, it is recommended to seek medical advice early. Detailed analysis is as follows:
If the polyp is smaller than 1 cm in diameter and the patient has no symptoms such as abnormal vaginal bleeding or menstrual irregularities, especially in women of reproductive age, some polyps might regress spontaneously with hormonal changes and surgery can be temporarily avoided. These polyps are often functional and can be monitored regularly via ultrasound. For example, small polyps formed due to hormonal fluctuations in adolescence or reproductive age might naturally shrink during the menstrual cycle.
When the polyp is larger than 1 cm in diameter, or when it is accompanied by abnormal bleeding, prolonged menstruation, postmenopausal bleeding, or affects fertility, surgical removal should be considered. Larger polyps may lead to anemia and infertility. Postmenopausal women have a higher risk of malignant transformation in such polyps, and surgical excision can confirm the pathological nature. Surgery is usually performed via hysteroscopy, allowing precise removal of the polyp and minimizing damage to the uterus.
Endometrial polyps should be evaluated by a physician promptly upon detection. The doctor will制定 a treatment plan based on the size of the polyp, symptoms, and individual patient factors. Postoperative personal hygiene is important to prevent infection, and follow-up visits should be conducted as directed by the physician.
