As long as there is no abnormality in the body and there is no pain or other discomfort, there is no need to worry. Just keep a calm mind, eat healthy and you'll be fine. So why is there still a little bit of menstruation on the eighth day?

Causes of long menstrual periods

1. Central nervous system-hypothalamic abnormalities

It includes mental stress, such as reactions caused by mental stress such as environmental changes, excessive tension, and mental shock; as well as weight loss, anorexia nervosa, excessive exercise, and drugs that cause dysfunction or inhibition of the hypothalamic secretion of gonadotropin; in addition, congenital diseases or brain malformations and tumors cause abnormal hormone secretion.

2. Pituitary abnormality refers to abnormal secretion of gonadotropin caused by pituitary lesions. There are congenital factors as well as acquired lesions, such as pituitary tumors.

3. Ovarian abnormalities

Menstrual abnormalities are caused by congenital ovarian dysplasia, ovarian dysfunction or secondary lesions, such as polycystic ovary syndrome, with clinical manifestations of infrequent, irregular menstruation, hirsutism, obesity, etc.; functional ovarian cysts; ovarian tumors, etc., which affect menstruation due to hormonal changes. Then there is the severe pelvic infection, which can also damage the bilateral ovarian tissue, thus affecting menstruation and even causing permanent amenorrhea, among which tuberculosis lesions are the most common.

The dangers of prolonged menstruation

Under normal circumstances, menstruation usually lasts 3 to 7 days, with a total bleeding volume of less than 100 ml, with the heaviest bleeding occurring on the 2nd to 3rd day. Absence of menstruation or prolonged duration of menstruation may be caused by gynecological diseases.

If the menstrual period lasts too long, it will easily lead to anemia, induce gynecological infections, and cause symptoms such as physical fatigue and sleepiness. Secondly, a long menstrual period can easily lead to the following six diseases.

Such as thrombocytopenic purpura, aplastic anemia, etc., are often accompanied by menstruation. If severe uterine bleeding occurs, the menstrual period will be prolonged. Other conditions such as chronic anemia, chronic hepatitis, cirrhosis, nephritis, etc. can make the blood vessel walls fragile, increase permeability and cause bleeding.

Dysfunctional uterine bleeding. For example, anovulatory dysfunctional uterine bleeding and irregular endometrial shedding both cause prolonged menstruation due to endocrine dysfunction.

Endometriosis. It often causes menorrhagia or prolonged menstruation due to affecting the contraction of the uterine muscle layer or strengthening the endometrium.

Pelvic inflammatory disease. Pelvic inflammation, intrauterine polyps, endometritis, etc. are all caused by poor intrauterine blood circulation, degeneration and necrosis, or pelvic congestion, which lead to excessive menstruation and prolonged menstruation.
