I'm a hypothyroid patient. I have been diagnosed almost 5 years ago with this illness. At first my tsh level was >150, but it decreased. Now it is 43. I'm taking thyrox 100 on regular basis. I'm skinny male 20 yrs old. Should I include calcium tablets to my medicine. And can I go to gym for light exercising. And is there anything that I should know that can degrade my health later in my life. Thank you.
