Have you been properly diagnosed by an endocrinologist for hyperthyroidism? If yes, then the doctor must have told you how the treatment will be. Some hyperthyroidism can be controlled through proper medication as well diet. Has your endocrinologist taken a blood sample to check the levels of you thyroid stimulating hormones (TSH) and also your triiodothyronine (T3) and thyroxine (T4)?

I had hyperthyroidism before and had to take radioactive iodine theraphy and I know how you feel right now. Try to have it controlled before summer comes because one of the symptoms that hyoerthyroidism presents is intolerance to heat.

Hope everything will be fine with you soon...
