hello dr,am a woman of 34 yrs, unmarried. as i find it difficult to lose weight and suffering from excessive hair loss of late so my doc sugested total t3 & t4 along with TSH test. my t3 is 123 ng/dl, t4 is 8.9 ug/dl, and tsh is 7.61 uIU/ml. she prescribed me thyrox 50 once a day before meal (breakfast). my question is, as my total T3 & T4 are within the nomal range then why my tsh is high? should i continue with the medicine or go for detailed analysis of the same. thank you...
