I have a question about my medication change and how it will take to affect my TSH. My medication was just increased from 100 mcg. to 125 mcg due to a high TSH indicating my thyroid was again low. I think that was contributing to my slow weight loss. I've been on Atkins for 9 weeks now and have lost only 20 lbs despite daily exercise and following the diet. How long will it take on the new medication dose before I should expect a little more weight loss? I would think my weight loss should improve if my TSH comes back into a normal range but I don't know how long that will take.
