Menopause or puberty: During menopause, hormone levels fluctuate, causing abnormal menstruation. In addition, pubertal women are not yet mature in the positive feedback mechanism of the center to estrogen, which will affect the ovaries and the neuroendocrine system, affecting menstruation and causing menstrual abnormalities. 2. Mental factors: long-term anxiety, depression or tension, stress, etc. will have an impact on the function of the hypothalamus and pituitary gland, resulting in neuroendocrine disorders and causing menstrual abnormalities. 3. Drug factors: If you often use some contraceptives, it will also affect the hormone level in the body, and abnormal menstruation will occur. 4.
