As I wrote in my previous post, I have been told by my gp that my tsh is slightly high but not put on any treatment. Sunday I've been taken to hospital with heart palpitations. While in there all tests came back fine except thyroid. They said the same slightly hy tsh 5.6 t4 ok and my potassium levels a bit low. On hospital they put me on potassium for 4 days. On my release paper from hospital diagnosis sais hypothyroidism. The letter has been sent to the GP also. Do I fallow this? Do I need to kick off at my GP to be put on medication? I don't understand if I should or not be getting treatment. If thyroid was the cause of my heart problems, surely treatment is necessary, what should I do?
