Symptoms of hyperthyroidism
are difficult to concentrate ,fatigue,increased sweating, increased appetite,heat intolerance, weight loss
, rapid heart rate
Your symptoms could be suggestive of hyperthyroidism. I would suggest that you get your blood test
T3, T4, TSH done. This blood test will help to clear your doubt. If the levels are abnormal then medicines can be started. Also get your Electrocardiogram (ECG) done to rule out any heart problem.
Wish you good health.
