In preparation for my 65 year old health check today, I did some research on this site and was shocked that GPs and other health professionals have never mentioned the relationship between T3 and T4. I have been taking thyroxin since 1994 and am currently on 200mcg a day. This was because some years ago I upped my dose from 150-200mcg based on a book on underactive Thyroid which suggested this would increase energy and weight loss ! My health test was fine today apart from the fact I am clinically obese and although I have been attending weight watchers and slimming world, I struggle to lose any weight. I would welcome advice on wAy forward - thinking of 1) reducing thyroxin to 100mcg a day 2) see GP and ask to be referred to endincrinologist re prescribing T3 3) get blood tested for T3 and T4 as a year ago only tested for T4
Any other suggestions?
