What is the cause of black menstrual blood?

Women often encounter abnormal menstruation in their lives. As we all know, menstruation is a good friend that we must have every month. If the color of menstruation starts to become abnormal every time, then our female friends will definitely be very worried. Some women have experienced black blood in their menstruation. So what is the reason for black blood in menstruation? Let's take a look below:

Reason 1 for black menstrual blood: Qi stagnation and blood stasis cause black menstrual blood: irregular menstruation, more or less menstrual flow, purple-red color, clots, and difficulty in menstruation. Or it may be accompanied by lower abdominal pain that refuses to be pressed, or distension and pain in the chest, flanks, breasts, and lower abdomen, abdominal distension and discomfort, purple tongue or petechiae, thin white or thin yellow tongue coating, and stringy or astringent pulse. The treatment is suitable for promoting blood circulation, removing blood stasis, regulating qi and relieving pain.

Reason 2 for black menstrual blood: Black menstrual blood due to kidney deficiency: irregular menstrual cycle, small amount of menstrual blood, light red or dark red in color, and thin in texture. 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.

Reason three for dark menstrual blood: Dark menstrual blood due to deficiency of both Qi and blood: early or late menstrual cycle, increased or decreased menstrual volume, prolonged menstrual period, light color, and thin texture. Or there may be pain in the lower abdomen, dizziness, fatigue, pale or sallow complexion, poor appetite and loose stools. The tongue is pale red and the pulse is thready and weak. Treatment should focus on replenishing both Qi and blood. How to regulate dark menstrual blood in daily life? Experts point out that women with dark menstrual blood should keep a happy spirit and avoid mental stimulation and mood swings. Some women may experience lower abdominal distension, back pain, breast pain, mild diarrhea, fatigue, drowsiness, emotional instability, irritability or depression during menstruation. These are all normal and there is no need to be overly nervous. Pay attention to hygiene and prevent infection. Pay attention to the hygiene of the external genitalia. You must not have sexual intercourse during menstruation. Keep warm and avoid cold stimulation. Avoid overwork. If black menstrual blood appears during menstruation, don't be nervous and can seek Chinese medicine treatment. Also, please note that you should not eat raw or cold food during menstruation to avoid dysmenorrhea. People with heavy menstrual bleeding should avoid eating brown sugar. Avoid eating raw, cold, spicy or other irritating foods. Drink more water to keep your bowel movements smooth. People with hot blood should eat more fresh fruits and vegetables before menstruation, and avoid eating things that stimulate fire such as onions, garlic, leeks, and ginger. People with qi and blood deficiency must increase their nutrition in daily life, such as milk, eggs, soy milk, pork liver, spinach, pork, chicken, lamb, etc., and avoid eating raw and cold fruits and vegetables. Why does premenstrual syndrome occur? Why does premenstrual syndrome occur?

Some women experience greater mood swings and even suicidal thoughts 1-2 weeks before their period, accompanied by general edema, nausea, diarrhea, etc. This is clinically known as premenstrual tension syndrome. So why does premenstrual syndrome occur? Why does premenstrual syndrome occur? Experts say that the pathogenesis of premenstrual syndrome is still unclear, but it may be related to the following factors:

(1) Vitamin B deficiency: Those who take oral contraceptives may experience symptoms similar to premenstrual syndrome, which can be corrected clinically with vitamin B6, as it can promote the clearance of excess estrogen in the body and regulate emotions and behaviors.

(2) Endorphin theory: Since changes in endorphin levels can affect mental and neurological factors, intravenous administration of endorphins can increase prolactin concentrations. Animal experiments also show that antidiuretic hormone increases after endorphin administration. The endorphin inhibitor naloxone can change the secretion of luteinizing hormone after acting on the endorphin receptors, and β-endorphin changes with the menstrual cycle. Therefore, it is proposed that premenstrual tension syndrome is caused by changes in endorphin concentrations during the luteal phase.

(3) Imbalance in the ratio of estrogen to progesterone: This may be caused by relatively high estrogen levels and relatively insufficient progesterone levels; it may also be caused by abnormal tissue sensitivity to progesterone. Under normal circumstances, progesterone promotes the excretion of sodium and water in the distal renal tubules, while estrogen causes water and sodium retention through the renin, angiotensin II, and aldosterone system. Therefore, an imbalance in the ratio of estrogen to progesterone can cause signs such as weight gain.

(4) Psychological factors: closely related to the degree of premenstrual syndrome. Some patients have prominent mental symptoms, and mood swings and mental stress can aggravate the original symptoms. Experts remind that a reasonable diet structure can help relieve symptoms. Attention should be paid to maintaining adequate intake of vitamins and trace elements, such as vitamin B6 and vitamin E; a high-carbohydrate, low-protein diet can improve the mental symptoms of premenstrual syndrome. Bad eating habits can aggravate symptoms, therefore, patients with PMS should limit salt intake, avoid or reduce caffeine intake, etc.

After knowing the reason why the color of menstrual blood turns dark, if you face the same problem one day, it is recommended that our female friends do not be overly nervous. I believe that through the above description, many women have a better understanding. When facing symptoms, they must first find the cause in time and then treat it symptomatically. Dark menstrual blood is abnormal, so timely improvements must be made.
