hi Dr, I am (almost) 53 y/o woman 5.7 and weigh around 66kgs, In 2004 I was diagnosed with Hashimotos disease now taking 100mcg Thyroxine daily as well as hormone replacement Kliovance... My last thyroid function test reading was Free T4 31.4 / TSH 0.01 / Free T3 5.6 . Thyroxine was reduced from 150mcg to improve TSH level but not effective - I have felt for a number of years that I retain fluid, I maintain a healthy diet , do not exercise on a regular basis but do enjoy walking when time permits...I would like to drop 5-8 kgs, but find it very difficult to budge the weight....I d appreciate your general comment on the info I ve provided Thanks Helen
