Menstruation quantity little duration is long what reason causes

Low menstrual flow and long duration may be caused by a variety of reasons, including endocrine disorders, endometrial lesions, ovarian dysfunction, excessive diet or malnutrition, mental stress, drug effects, and other systemic diseases. 1, endocrine disorders hormone levels imbalance in the body, such as estrogen levels are too low or progesterone deficiency, may affect the normal growth and shedding of the endometrium, resulting in reduced menstrual volume and abnormal duration. For example, polycystic ovary syndrome and other diseases will lead to elevated androgen levels, inhibiting ovulation, resulting in menstrual disorders. Endometritis, endometrial tuberculosis, endometrial adhesions and other lesions will damage the endometrium, affecting its normal function, resulting in less menstrual volume and long duration. Endometritis can be caused by bacterial infection and other pathogens, destroying the structure of the endometrium; endometrial tuberculosis will gradually destroy the endometrium. 3, ovarian function decline with age or other factors lead to ovarian function decline, follicular dysplasia or ovulation disorders, estrogen secretion decreased, causing menstrual changes. 4, excessive diet or malnutrition The body lacks the necessary nutrients, affecting the normal operation of the endocrine system, leading to menstrual abnormalities. Excessive diet may lead to low body fat content, affecting hormone synthesis. 5, mental stress is too high for a long time in a state of high tension, anxiety, will interfere with the nervous system regulation of endocrine, and then affect menstruation. 6, drug effects Some drugs such as contraceptives, antidepressants, etc. may affect menstruation. Long-term use of contraceptives may change hormone levels in the body, causing menstrual changes. 7, other system diseases such as hypothyroidism and other endocrine diseases, may also affect menstruation. Thyroid hormone plays an important role in body metabolism, thyroid dysfunction will affect menstruation. In addition, if the menstrual volume lasts for a long time, it is recommended to seek medical attention in time, carry out relevant examinations, such as ultrasound examination, sex hormone determination, thyroid function examination, etc., to clarify the cause, and carry out targeted treatment under the guidance of the doctor. At the same time, maintain good living habits, such as balanced diet, moderate exercise, regular rest, reduce mental stress, etc., help to maintain normal menstruation.
