I am 20 years old and last year I was diagnosed with Hashimoto. It was by completely by chance. I remembered that when I was 14 my the school doctor told me that I had an enlarged thyroid, but then the GP just did the normal neck checking and said it there was nth wrong with my thyroid.I am not sure whether all this time I had Hashimoto or some prolonged transient stage of hypothyroidism which eventually lead to Hashimto. The lab reports showed decreased TSH when I asked for those tests by chance so the endocrinologist suggested that the disease had not progressed for long, it was just the start with the emptying of all the thyroid . However, I have always had problems with losing weight,ALWAYS and of course the genetic makeup allows some of us to have a more active metabolism, but I always wonder whether for me is that only that or hypothyroidism has sth to do with it during all these years.
I take 50mg L-thyroxine since the beginning and the last time the lab reports showed very low TSH level but ok T4(dont remember exact values). The problem is that it is still very difficult for me to lose weight. I mean I do not do that much of sports, running 2-3 times per week for 20-30 min but I am very careful with my dietary intake, only 1 slice of bread per day, little meal in the evening, try to avoid sweets, buy juices with low calories and little sugar and in general it seems that compared to the rest of my friends I am very balanced with my diet but somehow I gain weight extremely easy.
