Hi I have a thyroid disease it went undetected for years I was never a large child but as soon as I hit my teens my weight soared I was always told you are what you eat cut down on the usual fried food , ( never eat fried food) chocolate ( don t eat as I m a migraine suffera) crisps ect I hardly ever touch, I do NOT over eat ,yet still my weight sores I am now 60 and have been taking thyroxin 200mg daily for years , and also suffer from chronic Arthritus in my joints, I have found it a little difficult to swallow lately, my hair comes out quite a lot , is there some thing more than my rhyroid going on here ?
