Why do uterine fibroids delay menstruation? Why do uterine fibroids cause irregular menstruation?

Uterine fibroids are a common benign tumor in women. They mainly originate from the smooth muscle cells in the endometrium and myometrium. Uterine fibroids usually do not cause symptoms, but in some cases, they may cause delayed or irregular menstruation.

First, uterine fibroids can affect the normal growth and blood supply of the endometrium. The endometrium is a layer of tissue lining the uterus that gradually thickens and eventually sheds during the menstrual cycle, leading to menstruation. However, when uterine fibroids grow and press on the endometrium, it may interfere with the normal shedding process of the endometrium, causing menstruation to be delayed.

Secondly, uterine fibroids may also cause abnormal contractions of the myometrium. The myometrium is the thickest layer of muscle tissue in the uterus, which is responsible for contracting during the menstrual cycle to expel the shed endometrium from the body. However, when uterine fibroids are present, it may interfere with the normal contraction of the myometrium, leading to irregular menstruation.

In addition, the growth of uterine fibroids may also affect ovarian function. The ovaries are the key organs in the female reproductive system responsible for ovulation, and the normal occurrence of menstruation is one of the manifestations of ovarian function. The weight and pressure of uterine fibroids may interfere with the normal function of the ovaries, causing delayed or irregular menstruation.

In general, uterine fibroids can affect the normal function of the endometrium, myometrium, and ovaries, which may lead to delayed or irregular menstruation. For women with uterine fibroids, if menstruation is abnormal, they should seek medical attention and treatment in a timely manner.

Popular Science Introduction: Uterine fibroids are benign tumors that do not cause symptoms and do not require treatment in most cases. However, for some women with larger or more symptomatic fibroids, surgical treatment may be required. The surgery can be a traditional resection or a more advanced laparoscopic surgery or uterine artery embolization. The choice of treatment for uterine fibroids should be based on individual circumstances, so it is recommended that patients consult a doctor before deciding on a treatment method. Regular physical examinations are an important measure for the prevention and early detection of uterine fibroids. Female friends should maintain good living habits and seek medical treatment in time to protect their health.
