Identify the real cause of menorrhagia

6 caused major cause of excessive menstrual

1, uterine fibroids

Uterine fibroids (uterine fibroids) is the most common benign tumor of female genitalia. It is reported that the incidence of women of childbearing age 20-30% of patients with uterine fibroids but no need to panic, because fibroids is very low risk of malignant transformation to sarcoma, about 0.5%. The development process by fibroids and the relationship between uterine muscle wall can be divided into intramural fibroids, subserosal fibroids and submucosal fibroids.

Dr Cheung said, menorrhagia, menstruation, abdominal palpable mass, pressure symptoms (such as frequency, urgency, urinary retention, etc.), increase the amount of vaginal discharge or bloody discharge is a common symptom of uterine fibroids, but many There is no such symptoms in patients with uterine fibroids, only when the examination found to have fibroids. Menorrhagia caused by uterine fibroids are several possible factors:

(1) fibroids are sex hormone dependent tumor, local high estrogen levels and their receptors in the high sensitivity allows endometrial hyperplasia;

(2), uterine fibroids can increase, increased endometrial surface area;

(3) fibroids can affect uterine contractions.

2 IUD

In China, women most commonly used method of contraception is the intrauterine device (commonly known as "the Ring"), some women will appear in the ring after the phenomenon of menorrhagia. Dr Cheung pointed out that the ring caused by menorrhagia attributed to the following main reasons:

(1) intrauterine device (IUD) mild stimulation of endometrial injury and chronic inflammatory reaction;

(2) IUD caused an increase in endometrial production of prostaglandins, a large number of prostaglandin can enhance the effect of estrogen;

(3) IUD affect the uterine contraction.

3, anovulatory dysfunctional uterine bleeding

Dysfunctional uterine bleeding is abnormal ovarian hormone secretion mechanism of abnormal uterine bleeding caused. Anovulatory DUB in which patients lose the normal menstrual cycle and bleeding self-limiting, often engendered menstrual cycle disorders, menstruation, as excessive, irregular vaginal bleeding and so on. Occur in adolescent and perimenopausal period. Anovulatory uterine bleeding in patients with ovarian follicular development, atresia turn, no corpus luteum formation, ovarian secretion of estrogen without progesterone, the endometrium by the continuing role of estrogen, the occurrence of pathological changes in proliferation; and self-limiting endometrial bleeding Defects in, it may appear as excessive.

4, pelvic inflammatory disease / pelvic venous congestion syndrome

Female anatomy and physiology because of its unique structure and family and social functions, sexually active women, menstrual, post-natal and post-operative of family planning, reproductive organs susceptible to the invasion of pathogenic microorganisms and cause pelvic inflammatory disease. Recent years due to the spread of sexually transmitted diseases, pelvic inflammatory disease are caused by increased significantly. Endometritis, pelvic venous congestion and inflammation are caused by uterine hypertrophy may lead to menstrual cramps, as excessive.

5, primary menorrhagia

Some women in the first period when expressed as menorrhagia, the exclusion of a systemic disease or genital lesions caused by menorrhagia, this situation can be considered primary, physiological, such as congenital uterine hypertrophy, need for active prevention of complications caused by menorrhagia. Dr Cheung In particular, women after menarche, the age in the normal passing through sudden menorrhagia, you need to make the correct diagnosis and timely medical treatment.

6, other special reasons

Suffering from blood diseases, long-term use of anticoagulant drugs, as well as by other endocrine disorders caused by menorrhagia, such as mild hyperthyroidism occur in patients with early symptoms of menorrhagia, the treatment need for the cause of primary disease treatment.
