Always get a copy of your blood tests with the ranges for your own records and so you can post if you have a query.

Your underacticre thyroid does not go 'overactive' as the GP's say when they believe it is right to keep you 'within the range'. I don't know much about Addison's disease.

This is what happens when your dose is adjusted according to the TSH alone. Read last question/answer on page

Ok thanks for your reply Addison is another autoimmune disorder, but of late I have felt rubbish constantly tired, menopausal, and not sleeping, I seen my endo consultant who took all my routine bloods, which states my thyroid is now "over active" they don't do free t4/3 but say reduced mess down to 75mcg from 100mcg, I am not sure why this happens and will the lesser dose make me even more tired thanks again

If they don't test T4/T3 then they are presumably going on TSH alone. If you start to feel worse you should try to persuade them to either do the T4 test or let you go back to 100mcg. How are your Vitamin D, B12 and Ferritin levels? Do you have any hyper symptoms?

I don't suppose you have been taking your meds before the bloods were taken, this will show a high reading! Maybe take the thyroid meds after your next blood test. I also have Addison's and I know it's always an up hill battle trying to make sure your body feels normal.

Not what you're looking for?
