<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, I have been experiencing irregular periods and excessive hair growth on my face and body. I also experience acne on my skin from time to time.  <response>: It sounds like you may be suffering from Polycystic Ovarian Syndrome or PCOS. To confirm the diagnosis, we will need to conduct a series of medical tests including hematologic tests, a pelvic exam, and ultrasonography. We will also need to examine your breasts, perform a lipid panel test, and check if you are pregnant with a standard pregnancy test. Finally, we will need to conduct a Hemoglobin A1c measurement to check for insulin resistance.
