If the patient is determined to have polycystic ovary syndrome and the prolactin level is not particularly high, it is important to consider that there is a relationship between the patient’s increased prolactin level and polycystic ovary syndrome. Therefore, in this case, it is recommended that patients choose drugs to target the treatment of polycystic ovary syndrome. For example, the use of Daying-35 with metformin and other treatment, treatment 3-6 months and then review, if the effect is not good can repeat the treatment, if the effect is good, you can stop a period of time and then review. Polycystic ovary syndrome is very difficult to be completely cured, and it is mostly a lifelong disease. Depending on the patient’s age, the degree of disease lesions, and whether there are some requirements such as fertility requirements, different adjustments can be made. For example, if the patient has no reproductive requirement, the main purpose is to regulate the menstrual cycle, and if the patient has reproductive requirement, the main purpose is to regulate the fertilization. If the patient is in the perimenopausal period, the main purpose is to prevent osteoporosis, endometriosis, breast lesions and so on. If the prolactin level does not decrease after treatment of polycystic ovary syndrome, bromocriptine can be chosen after examination to exclude pituitary tumor.
