I think I must have hypothyroidism - I have almost all of the symptoms that Wiki lists! Extreme fatigue (took today off), poor memory and concentration, weight gain with little appetite, blotches of dry skin on my legs. I should also mention that my sister is being treated for it and, like myself, is Type 1 diabetic. I think I have had this condition for a long time, but when tested, my doctor said I was on the side but didn t take any further investigation or prescribe anything. Generally, energy levels, inability to concentrate at work and borderline depression are what I am suffering from. Any answers, questions etc would be gratefully received! Thanks, John. 604-328-8725
