#1 No need to be scared and you are not alone. Hair loss, tiredness, cysts, heart probs and cold hands all point to a thyroid problem. Find a good endocrinologist. If your TSH comes back as normal, this does not rule out a thyroid disorder. Go get a blood test with FULL THYROID PANEL including TSH, thyroglobulin antibody titer, thyroid peroxidase antibody, lipid profile, free thyroxine index, T4, T uptake.Regarding the hair loss: More than likely, the thyroid is causing this, but you may also want to check the following: I would also suggest an iron panel blood test be done including ferritin - hair loss can also be caused by anemia and is frequently associated with thyroid probs. Normal blood tests for iron only look at the amount of iron floating around in your blood and can be affected by what you ate recently. The ferritin level will tell you real iron values stored by your body. Also go to a dermatologist and rule out skin issues such as alopecia, as the cause for hair loss. Also when you get blood work, ask them to check your testosterone levels (free and total), DHEA sulfate and androstenedione. Abnormal testosterone levels can cause hair loss. In short, go get yourself fixed and take responsibility for your health by pushing doctors to investigate the cause of your problems - after all, you are paying them for their services.Best wishes.
I'm not sure how to answer your question, or even what exactly it is.
You have several issues, and there are no medical professionals on this forum that are officially associated with MedHelp. This is a patient to patient support forum only. I'm afraid that no one can offer you any concrete answers, except to go to your doctor with a list of your questions, and don't leave until they are answered to your satisfaction.
I'm so sorry that I can't offer much more advice than that. There is a thyroid forum here, as well as a cardiac one. Maybe you can try there--until you go to your doctor.
