There are many causes of endometrial polyps. One is the excessive secretion of estrogen in the body, leading to an uneven distribution of hormone levels. Furthermore, long-term use of health products and hormone medications can stimulate their development, as can gynecological inflammations from events like abortion, childbirth, or surgical procedures, all of which can lead to the formation of endometrial polyps. Additionally, high blood pressure and obesity are also high-risk factors for endometrial polyps. Therefore, it’s crucial to carry out a timely hysteroscopic examination once endometrial polyps are detected. This examination should take place three to seven days after menstruation at a hospital. If the polyps are larger than one centimeter in diameter, or if there is continuous vaginal bleeding, an immediate hysteroscopic polypectomy is necessary.

Can endometrial polyps be cured?

Endometrial polyps are a common gynecological condition clinically, and most of the time, they are not very harmful. Clinically, once endometrial polyps are discovered, it is recommended to assess with the local hospital's gynecology department whether surgical removal is necessary. Most endometrial polyps can be cured through surgical removal and will not affect the patient's daily life or future. However, it is important to note that endometrial polyps are very prone to recurrence.

How to regulate endometrial polyps

Patients with endometrial polyps, if they want to manage their condition, the majority is due to an infection. This is because the recurrence of endometrial polyps can occur during endometrial inflammation. The treatment for endometrial polyps generally requires hysteroscopic polypectomy at a hospital for symptomatic treatment. Patients with endometrial polyps generally experience menstrual disorders. Therefore, when managing, it is crucial to be aware that endometrial polyps can easily recur. Prevention of infection must be emphasized during management. Furthermore, endometrial polyps can lead to changes in menstruation. This generally affects fertility. Thus, after hysteroscopic polypectomy for endometrial polyps, it is essential to properly manage inflammation and provide appropriate treatment. Intercourse should be avoided within a month after the polyp removal surgery. If there are any abnormal conditions, it is necessary to seek hospital treatment for symptomatic management.

Do uterine polyps require surgery?

Endometrial polyps are caused by excessive growth of the endometrial lining, and can be single or multiple, with diameters ranging from a few millimeters to several centimeters. They can be pedunculated or sessile. Endometrial polyps smaller than one centimeter in diameter, if asymptomatic, have a natural resolution rate of about 27% within a year and a low rate of malignancy. If the polyp is large, greater than one centimeter, it requires hysteroscopic endometrial polypectomy or curettage. However, curettage has disadvantages, as it can easily miss polyps, and there is a high chance of recurrence after the surgery. Therefore, once an endometrial polyp larger than one centimeter is identified, it is advisable to promptly visit a hospital for examination and treatment. Postoperative treatment should be guided based on the pathological findings.

What should I do about endometrial polyps?

Endometrial polyps, if diagnosed, are generally treated within 3 to 7 days after the end of menstruation. You can go to the hospital to have the polyps removed under hysteroscopy. Postoperative anti-inflammatory and symptomatic treatment is then sufficient. The removed polyps should be sent for pathology analysis, and based on the pathology results, an appropriate treatment method can be selected. Generally, most endometrial polyps are benign, with a very small percentage having a tendency to become malignant. Endometrial polyps are prone to recurrence, so it is essential to undergo proper anti-inflammatory and symptomatic treatment after the removal of endometrial polyps. The diagnosis of endometrial polyps generally requires a hospital visit for a color Doppler ultrasound. After menstruation, if the ultrasound shows thickened endometrial echoes or uneven echoes, most can be diagnosed through this ultrasound. Treatment can only be performed surgically.

Do uterine polyps affect pregnancy?

Endometrial polyps refer to the hyperplasia of the endometrial lining due to inflammatory stimuli, resulting in many polypoid tissues. Whether endometrial polyps affect pregnancy mainly depends on the number and size of the polyps, and whether they cause clinical symptoms. First, if the polyps are small and few in number without causing an increase in menstrual flow, they generally do not affect pregnancy and do not require removal of the endometrial polyps, as removing them could instead easily damage the function of the endometrial lining. Second, if the polyps are large, over one centimeter, or there are multiple endometrial polyps, and they cause an increase in menstrual volume, this indicates that the endometrial polyps have impacted the woman's body. In such cases, it is necessary to use a hysteroscope to remove the endometrial polyps before trying to conceive.
