I am a woman who has amenorrhea (never having menstrual bleeding all my life). At age 20, I went to see a doctor and that was when I was diagnosed with amenorrhea. The doctor could not really figure out what was wrong with me - the ultrasound of my uterus checked out fine. He thinks I may have problems with my hormones. He put me on birth control pills. I did have regular menstrual bleeding during that time, but after a few months, I stopped due to potential risks/side effects (heart issues, etc.). Since then, amenorrhea returned. I am now 46 years old, overweight (1.7 meters, 95 kg), and generally in good health. I haven t seen a doctor for over 15 years. I have made an appointment to see one for physical check-up soon. So I am nervous and want to educate myself more on amenorrhea before seeing the doctor. From my research, I may have issues with low estrogen, thyroid and/or pituitary gland although it says that most of the symptoms point to weight loss and excessive hair growth. I am the opposite - I can t lose weight and I have thinning hair on top of my head. My armpit hair and pubic hair are normal (not very thick). What do you think may be wrong with me? Also what kind of risks am I at? (Breast cancer? Thyroid cancer? Etc.) Can you guess what kind of recommendations/tests my doctor will give me? Thank you very much.
