I have been having dizzy spells, feeling tired, not sleeping very well, i have had 3 bad falls in the last. 6 months. My hair is slowly falling out, i take a lot of tablets for my high blood pressure and i am also diabetic. My memory is being affected i forget what i am saying when i am half way through a sentence. I have quiet a few other problems, could these all be associated with my thyroid problem. I also joined a slimming club 2 years ago it took me 18 months to loose 2 stone, and since christmas have regained 1 of these stones, but have stuck to the diet plan 100%.
