Why is my menstrual period dark and light?

Every woman has her own menstrual cycle, but because everyone's physical constitution is different, various problems may arise. For example, some people may experience irregular menstruation, abnormal menstruation, darker menstruation and less menstruation. So what's the matter with dark and less menstrual blood?

1. The dark color of menstrual blood is caused by qi stagnation and blood stasis, which causes menstrual blood to accumulate in the uterus for a long time. Dysmenorrhea is often related to this, or it may be caused by certain gynecological inflammations. Because menstrual blood is mixed with sloughed endometrial fragments, cervical mucus and vaginal epithelial cells, it looks dark in color and is not as bright red as the blood flowing out of broken skin. There are also some small thin fragments mixed in the menstrual blood. And the menstrual blood is relatively small, and the longer it stays in the uterus and vagina, the darker the color becomes. Long-term scanty menstruation may cause amenorrhea or infertility. Dark menstrual blood is a sign of menstrual irregularity and should be treated and regulated in the hospital. Irregular menstruation can be affected by many factors, such as excessive fatigue, bad mood, eating too much cold or spicy food, catching a cold, being sick, etc.

2. Small amount of dark menstrual blood is also caused by irregular menstruation in women, and there are many reasons for irregular menstruation in women. In addition to certain gynecological diseases that can cause irregular menstruation in women, irregular menstruation is often related to improper diet during menstruation, colds, and flu. Therefore, women during menstruation should pay special attention to keeping warm and avoid spicy, irritating and cold foods. It is also important to maintain emotional stability.

3. Excessive levels of follicle-stimulating hormone and luteinizing hormone in the fluid feedback inhibit the ovaries from producing estradiol and progesterone. This condition is called premature ovarian failure. It first causes a decrease in menstrual volume, a delay of 1-2 months in the menstrual cycle, and finally amenorrhea.

4. Elevated testosterone (androgen) in the serum is common in polycystic ovary syndrome. Increased testosterone can neutralize estradiol in the blood, reducing estradiol and affecting the development of follicles and ovulation. At the same time, excessive testosterone can hinder the normal development of follicles and cause them to atrophy and atresia.

5. Increased pituitary prolactin (PRL) in the blood inhibits ovarian dysfunction. It may manifest as infrequent menstruation, reduced menstrual volume, anovulation, luteal insufficiency and finally amenorrhea.

Why is my menstrual period so dark and scanty? The above introduces some reasons for irregular menstruation. We cannot rule out the possibility that it is caused by some medical reasons. It may also be caused by lack of attention, excessive fatigue, or some external conditions. We must pay attention to it and seek treatment in time.
