Many female friends will judge their physical health by observing whether their menstrual cycle is normal. Sometimes, due to various reasons, there may be an increase in menstrual flow or a sudden decrease in flow, and the color may also change, such as a decrease in menstrual flow turning black. Let's take a look at what causes a decrease in menstrual flow turning black?
1. Endocrine reasons: If hormone secretion is disrupted or ovulation is abnormal. In addition, tumors or underdeveloped uterus can also cause reduced menstrual flow and blackening.
2. Endometrial abnormalities: If a female friend undergoes multiple induced abortions, curettage can cause thinning of the endometrium, which can lead to endometrial damage and adhesions in the uterine cavity. Mild cases may result in less menstrual flow, while severe cases may lead to amenorrhea.
3. Dietary reasons: Excessive dieting, many women will not eat scientifically in order to lose weight, leading to malnutrition and endocrine disorders. This will lead to a decrease in menstrual flow in women. In addition, if women eat too cold during menstruation, they will be stimulated, causing excessive constriction of blood vessels in the pelvic cavity, resulting in reduced menstrual flow and even amenorrhea.
4. Too much pressure: Poor mood, excessive life pressure, and holding back anger can cause endocrine disorders, leading to reduced menstrual flow.
5. Drug reasons: The use of drugs for treating mental illnesses, endocrine drugs, or intrauterine devices may cause menstrual irregularities, resulting in low doses and black color.
