Search Bookworm 1961, she posted about weightloss issues yesterday? and had loads of comments, you are not alone. I cant help as have the opposite problem, put on 7 stone in last 3 years.


It is unusual. (You must make an an appointment to discuss weight loss with GP.

Did you gain a lot of weight before you were diagnosed? 50mcg of levo is a starting dose and your TSH is nearly 3, so the aim should be 1 or lower.

Weight gain - not weight loss - is a clinical symptom of hypothyroidism.

Best to have it checked out. There are always some who go against the norm but better to make sure that's the only reason and not something you need to be concerned about.
