Causes of brown menstrual discharge

Irregular menstruation and abnormal leucorrhea are both common physiological diseases in women. Due to the different degrees of severity, if the symptoms are mild, they will recover quickly as long as you pay attention to conditioning. However, if the condition is serious, it is necessary to analyze the causes one by one and prescribe the right medicine. Some women have brown vaginal discharge after menstruation. Is this serious or not? What is the reason for brown vaginal discharge during menstruation?

Brown vaginal discharge after menstruation can be divided into physiological and pathological types, and the causes and characteristics are different. Here we will talk about physiological leucorrhea and pathological leucorrhea respectively. Physiological leucorrhea is a white, thin, paste-like liquid that is generally odorless. Under normal circumstances, leucorrhea plays the role of moisturizing the skin of the labia and vagina. The sebaceous glands of the labia secrete a viscous milky fluid; the Bartholin's glands secrete a colorless, clear, acidic fluid; the vaginal epithelium has no glands, and its white, thin, paste-like fluid is the exudate of the vaginal mucosa and is acidic; the cervical mucus is alkaline, like egg white; the endometrial secretions are thinner than the cervical mucus and in smaller quantities. The amount of vaginal discharge varies and is related to age, level and congestion of the reproductive organs.

The main reason why post-menstrual leucorrhea is brown is that after puberty, as the ovaries gradually develop to maturity and the secretion of progesterone, the properties and amount of leucorrhea vary with the ovarian cycle. In the middle of the menstrual cycle (before ovulation), due to the vigorous secretion of cervical glands, the cervical mucus component in the leucorrhea increases, resulting in a large amount of leucorrhea, which is clear and thin like egg white, to facilitate the passage of sperm; after ovulation, the amount of leucorrhea gradually decreases and becomes thicker; before menstruation, due to pelvic congestion, the vaginal exudate increases, and the amount of leucorrhea increases accordingly. After menopause, due to the decline of ovarian function, the decrease of sex hormones in the body, the gradual atrophy of the reproductive tract, the glandular secretion and the exudation of the vaginal mucosa are greatly reduced, resulting in a decrease in leucorrhea.

When a woman is sexually excited, a large amount of fluid is discharged from her vagina, which acts as a lubricant. In the past, people generally believed that during sexual excitement, it was mainly the Bartholin's glands that secreted more fluid, but now it is believed that the large amount of fluid mainly comes from the increased exudation of the vaginal mucosa. During sexual excitement, the blood vessels in the vaginal wall become significantly congested and dilated, producing a large amount of plasma exudate. Gynecological diseases often cause increased leucorrhea, which turns white or brown after menstruation. This phenomenon of increased leucorrhea and brown leucorrhea after menstruation has become symptoms of the disease, and its amount and properties are significantly different from normal leucorrhea.

Therefore, if a woman's vaginal discharge is brown during menstruation, it may be because the menstrual blood still remains in the vagina and has not been completely discharged. However, if a woman's leucorrhea is brown for a long time, she should go to the hospital for relevant examinations, as gynecological diseases may be the cause. In short, female friends should pay attention to their own hygiene to avoid gynecological diseases.
