Q: My daughter is 39 years old. Her menstrual flow started to decrease a few years ago, and now it is even less, and her cycle is also lengthened, often more than 40 days. She has been seen by both Chinese and Western doctors, and her hormone levels have been tested, and the doctor said it is premature ovarian failure. In addition to her low menstrual flow, she is also sexually frigid and has lost a lot of hair. What is the cause of her condition and how should she be treated? A: Normal women’s ovarian function begins to decline at the age of 45 to 50. If signs of decline appear before the age of 40, it is called premature ovarian failure, which is characterized by an increase in gonadotropin levels and a decrease in estrogen levels in the body. The causes of this disease are many, such as genetic factors, autoimmune diseases, and certain viral infections can cause premature ovarian failure. In addition, long periods of mental tension, psychological stress or poor nutrition may also be the cause of premature ovarian failure. When premature ovarian failure occurs, patients may experience amenorrhea or scanty menstruation, baking fever, sweating, insomnia and dreaminess, reduced vaginal discharge, vulvar atrophy and infertility, etc., which should be treated actively. Artificial cycle therapy with estrogen and progesterone followed by small doses of estrogen alone to induce follicular development is generally used. Artificial cycles need to be applied under medical supervision. Commonly used medications include Clomid, Tonic, or Bemisil, or hexestrol plus progesterone. Chinese medicine treatment mostly starts from nourishing the liver and kidney, strengthening the spleen and benefiting the qi and blood, and can be used according to clinical symptoms, such as Liu Wei Di Huang Wan, Zhi Bai Di Huang Wan, Jin Kui Kidney Qi Wan, Zuo Gui Wan, Da Yin Wan, Right Gui Wan, Strong Kidney Tablets, Yi Yao Wan, Jia Wei Yi Wan and Tian Zi Hong Female Gold Capsule. In the drug active treatment at the same time, should also strengthen self-care, work and rest, to ensure sleep, emotional optimism; diet should be reasonably balanced, eat more easily digestible, high protein, rich in estrogen-like substances, such as soybean products, bee products, dairy products, etc.; usually should also be moderate physical exercise.
