I've been having symptoms not related to my ME which seem to point to a thyroid problem. Particularly I've gained a lot of weight (2 stone) without eating too much (I was 11 stone a year ago at 38 and there was no change in diet or activity, but a significant and noticeable loss of appetite when the weight gain began), circles round my eyes, dry skin all over my head and face, dry hair. increasing dizziness and a constant lump in my throat. My mum has hypothyroid. I recently had a TSH test and it came back as normal, with a reading of 0.71, which I understand is at the low end of the normal range. Is it still possible that I have an issue? I'm at a loss as to what is causing the weight gain as I'm now down to under 1200 calories a day and still getting heavier. Is should add that I take Tramadol, Amitryptilene and gabapentin, but have done so for years without any of these side effects.
