Polycystic refers to polycystic ovary syndrome. It is not possible to determine how often these patients get their periods, some patients have continuous vaginal bleeding, some patients get their periods once every 2-3 months or even once every 6 months, and some patients may not get their periods for years. One of the main symptoms of polycystic ovary syndrome is sporadic menstruation. Most polycystic patients have irregular ovulation, which is characterized by sporadic ovulation or no ovulation, resulting in long intervals and irregular dates of menstruation, or even amenorrhea in severe cases. The disease is caused by high levels of androgens and luteinizing hormone and low levels of follicle stimulating hormone, which cause abnormal growth of the endometrium and eventually lead to menstrual disorders. Once confirmed, active treatment is needed, including progestin or short-acting contraceptives, to help normalize menstruation. In addition to medication, daily life should also be regulated. Patients should get enough sleep, not stay up late, eat a diet free of spicy and stimulating foods, and maintain an optimistic mood to facilitate recovery.
