i have been on eltroxin 100mcg for a few months now, i got blood work down last week an my TSH was 0.27 an T4 was 19.7 i feel the same at this dose as i did when the dose was lower when i first started eltroxin wich was great. the reason i upped it was cause of the weight issue. no matter what i do cant lose it even if i eat 800 to 1200 cals a day, im a 39 female that has to lose at least 30 pounds. i retain a lot of fluied so every few days i take a fluied pill an it helps for a few days. i have been on estrogen replacment for 4 years now cause i had cervical cancer. i red on line that when you take estrogen therpy that it can cut out the thyroid pill. when i got blood work on my estrogen levels i had more then i needed in my body so the doc told me to cut back on estrogel pump so i did. still not losing weight either way an not happy. i figured when i upped the dose of thyroid pill to 100 it would make the excess weight come off especially when im watchin my food intake? if anyone can help me out here it would be great!
