You will also talk about any family history of hormone problems, including diabetes.
The physical exam checks your thyroid gland, skin, hair, breasts, and belly. You will have a blood pressure check and a pelvic exam to find out if you have enlarged or abnormal ovaries. Your doctor can also check your body mass index (BMI).
