I was diagnosed with hyperthyroidism two years ago but I have been in remission for at least 10 months. I am noticing High heart rate, gasping for breath, increased sweating, weight loss and not increasing even when I am eating more. My free ‘T4’ level is on higher edge, normal ‘T3’ and ‘
TSH’ but I feel some symptoms of hyperthyroid. Is it possible to have Hyperthyroid even if levels are in range.
