Some women report that they sometimes bleed a small amount before their period. What is this bleeding before menstruation? Why does it happen? Does it have any impact on health? Let's ask the experts. If the amount of bleeding is really heavy, it is best to go to the hospital for consultation and then use medication to treat it. Therefore, there is no need to worry too much about what causes premenstrual bleeding. Let me introduce it to you below, I hope you can benefit from it.

There are many causes of vaginal bleeding before menstruation, which can be summarized into the following six categories.

(1) Ovarian endocrine dysfunction. The most common one is dysfunctional uterine bleeding.

(2) Uterine bleeding related to pregnancy. Common ones include miscarriage, ectopic pregnancy, hydatidiform mole, partial placental retention after delivery, incomplete uterine involution, etc.

(3) Inflammation. Common ones include vulvar ulcers, vaginal caruncle, vaginitis, cervicitis, cervical polyps and endometritis.

(4)Tumor. Such as uterine fibroids, vulvar cancer, vaginal cancer, cervical cancer, endometrial cancer, uterine sarcoma, ovarian cancer and choriocarcinoma.

(5) Injury, foreign matter and drugs. Common reproductive tract trauma such as vulvar and vaginal straddle injuries, and hymen or vaginal injuries caused by sexual intercourse can all cause bleeding. Uterine bleeding is often a complication of IUD insertion. Improper use of estrogen and progesterone can cause irregular vaginal bleeding.

(6) Vaginal bleeding related to systemic disease. Such as thrombocytopenic purpura, aplastic anemia, leukemia, hypothyroidism, liver damage, etc.

Some experts also say that it will appear before menstruation.

1. Dysfunctional uterine bleeding:

This situation may occur due to premature degeneration of the corpus luteum, resulting in a short luteal phase, or incomplete atrophy, which leads to a decrease in progesterone secretion.

2. Women who have sexual life need to consider the possibility of pregnancy. If pregnant, bleeding caused by embryo implantation, or miscarriage or ectopic pregnancy may occur, which may cause a small amount of bleeding before menstruation.

3. Uterine fibroids, cervical cancer, etc. may cause bleeding and require prompt hospital examination.

What causes premenstrual bleeding?

Premenstrual bleeding should also alert you to systemic diseases: abnormalities in platelet quantity and quality, coagulation and anticoagulation dysfunction including thrombocytopenic purpura, severe liver disease, and disseminated intravascular coagulation can all cause vaginal bleeding.

Premenstrual bleeding is likely caused by gynecological diseases, so once female friends experience premenstrual bleeding, they must go to the hospital for examination and treatment in time.

Experts say that although bleeding before menstruation is an abnormal condition, there is no need to pay special attention if the bleeding is not too much. Generally, this situation may be caused by a disorder of the woman's endocrine glands or menstrual disorders. Just pay more attention to your diet, adjust your work and rest time, and develop a good life pattern.
