I've been looking for answers for several years now and I'm hoping for an answer that makes since. Years ago I began gaining weight very fast , hair loss, excessive sweating and my dr sent me for tests which I did do and I was referred to an endocrinologist who said I must've been sick when I had tests done .I was sent back to retest.. again she said tests showed same results.. symptoms of hypothyroidism yet tests showed complete hyperthyroidism. She was unable to explain it but said ITS INHUMANLY POSSIBLE ...what can it be?
