Pregnancy with polycystic is not mandatory to take metformin. Polycystic pregnancy generally refers to pregnancy in women with polycystic ovary syndrome. Some patients with polycystic ovary syndrome are accompanied by insulin resistance, which leads to increased secretion of insulin by the pituitary gland, which in turn promotes increased secretion of androgens by the adrenal glands, causing infertility in patients. When such patients want to get pregnant, metformin can be used as an insulin sensitizer to increase the body’s sensitivity to insulin, reduce the insulin level in the blood, and at the same time reduce the secretion of androgens to make the ovaries ovulate, thus helping patients to get pregnant normally. Some patients with polycystic ovary syndrome do not have insulin resistance and may not take metformin. These patients are usually treated with direct ovulation treatment, which can promote follicle maturation and egg expulsion with drugs, but the treatment may take longer, 3-6 months. Patients with polycystic ovary syndrome need to have their blood glucose checked regularly after pregnancy by whichever means, as the disease predisposes patients to hyperglycemia, and high blood glucose can lead to miscarriage, giant babies and also increase the incidence of fetal malformations.
