Can my thyroid be functioning normally again

Dear Ask The Doctor: I STOPPED USING MY ELTROXIN FOR HYPOTHYROIDISM. I HAVE BEEN USING IT FOR 12 MONTHS. AND SO MANY PEOPLE TELLS ME I CAN DIE MY KIDNEYS WILL STOP FUNCKTIONING, MY THYROID WILL GO INTO RELAPSE. BUT I GAINED 25KG, I GOT SEVERE HEADACHES, CRAMPS IN MY LEGS, MOOD SWINGS, HOT FLUSHES, DEPRESION, LACK OF CONCENTRATION, BUT AFTER I STOPPED THE ELTROXIN IT IS ALL GONE I LOST 3KG IN 3 WEEKS. CAN I BELIEVE WHAT THE PEOPLE SAY OR DO I TRUST MY BODY AND LISTEN TO MY INNER VOICE TELLING ME MY THYROID STARETED TO FUNCTION AGAIN? AND HOW LONG CAN ONE USE ELTROXIN? IS IT POSSABLE THAT MY TSH LEVEL ARE BACK TO NORMAL? PLEASE IT WOULD BE GEATLY APPRECIATED IF YOU COULD ANSWET THESE QUESTIONS FOR ME. THANKS

Dear Wilma: There may be a chance that your thyroid may have started functioning again or it may be a sign that your medication infact needs to be increased due to poor control.The only sure shot way of knowing this is to get a blood test done to check your TSH levels along with T3 and T4. The result would then determine the further course of action. I hope this helps.
