The three fruits polycystic is most afraid of are false. Polycystic, or polycystic ovary syndrome, is a common reproductive endocrine metabolic disease whose main symptoms are menstrual disorders, hirsutism, acne, and infertility. Diet is mainly about stopping smoking, stopping drinking, controlling food calories and losing weight. Most fruits are not high in calories, and appropriate consumption will not cause adverse effects to these patients, while supplementing the appropriate nutrients. The cause of polycystic ovary syndrome is unknown, but it is mainly caused by a combination of congenital and acquired environment. Clinically, it is mainly necessary to regulate the menstrual cycle, and can be treated with short-acting compound oral contraceptives, progesterone, etc., which can be combined with metformin to improve insulin resistance, etc., if necessary. Since the vast majority of patients with polycystic ovary syndrome are overweight, weight control through diet is needed to improve quality of life and improve symptoms. This is combined with regular and effective exercise to reduce symptoms. Patients are advised to seek timely medical attention and standardized treatment under the guidance of a doctor.
