What causes scanty and dark menstrual period? How is it caused?

Once menstrual problems occur, they will bother women for a long time. This is a problem with a high probability of occurring in women's physiological phenomena. Menstruation is usually measured by the amount of bleeding. Healthy menstruation is characterized by a relatively stable and regular amount of bleeding each time. Abnormal menstruation often has a small amount of bleeding, color changes, etc. Let’s take a look at what is going on when the menstrual period is light and dark. How is it caused?

1. Caused by neuroendocrine dysfunction: mainly due to unstable or defective function of the posterior brain-pituitary-ovarian axis, that is, menstrual disorder.

2. Caused by organic diseases or drugs: such as vaginal inflammation, endocrine disorders, cervicitis, pelvic inflammatory disease, adrenal cortex dysfunction, diabetes, Sheehan's disease, etc. Menstrual irregularities may occur in women who use drugs to treat diseases, endocrine preparations, or intrauterine devices for contraception.

3. Deficiency of both Qi and blood leads to black menstruation: small amount of menstruation, irregular cycle, dark color, lighter color, thin texture, or frequent back pain or dizziness, sometimes fatigue, pale or sallow complexion, light red tongue and weak pulse. Treatment should be based on the replenishment of both Qi and blood.

4. Qi stagnation and blood stasis cause dark menstrual color: irregular menstruation, more or less menstrual volume, purple-red color, blood clots, irregular menstruation, or lower abdominal pain, breast pain, abdominal distension and discomfort, purple tongue or petechiae, thin white or thin yellow fur, and stringy or astringent pulse. The treatment is suitable for promoting blood circulation, removing blood stasis, regulating qi and relieving pain.

5. Kidney deficiency causes black menstruation in women: the menstrual cycle is irregular, the amount is small, the color is light red or dark red, and the quality is thin. Weak waist and knees, heel pain, dizziness, tinnitus, or cold lower abdomen, or frequent urination at night. The tongue is pale and the pulse is weak or slow. Treatment is suitable for tonifying the kidney and regulating menstruation.

6. When the menstrual volume is small and dark in color, it is actually caused by qi stagnation and blood stasis, and the menstrual blood accumulates in the uterine cavity for a long time during menstruation. Oligomenorrhea refers to less menstrual volume than normal people during menstruation, which is mostly caused by blood deficiency, qi stagnation, blood stasis, cold stagnation in the blood, phlegm obstruction and other reasons.
