Recently, we have seen an increase in the number of patients coming to our clinic for treatment of menorrhagia. These patients often also have a combination of infertility, obesity, and hirsutism. The typical presentation of such patients is an increasingly long menstrual cycle and a low menstrual flow. Often, menstruation needs to be induced by menstrual treatment before it will come. However, amenorrhea reappears after stopping the drug. These patients were tested for changes in the ratio between FSH and LH and the value of testosterone in the sex hormone six (better on the 2nd to 5th day of menstruation, which is the basal value), and examined for ultrasound findings of enlarged ovaries bilaterally, with more than 10 follicles developing visible in the ovaries. In combination with the patient’s clinical symptoms, polycystic ovary syndrome can basically be considered. The main treatment is to adjust the cycle, and for those who need to have children, to adjust the cycle and promote ovulation to help them get pregnant. Patients who are obese need to check their blood sugar and eat properly, and control their blood sugar if necessary.
