I was diagnosed with thyroid. Tsh 8.75 my weight was 86kgs i started taking thyronorm 25mcg within 6-7 months TSH came to normal and weight reduced to 56kgs. Due to rapid weight loss my muscles have become very weak and lose hence difficulty in walking. Whole body test was done rest every thing was normal..now i changed medicine and taking Euthyrox 25mcg since then weight loss stopped. Now weight is stable.. but how do I gain the lost muscle strenght.
