Hi there,
I was diagnosed with Hyperthyroidism back in 2003. My symptoms were rapid heart rate, intollerance to heat, weight loss, hand tremors, muscle weakness and I was very moody.

Mine was caused by an auto-immune condition called Graves Disease but there are various different causes.

I was put on thyroid suppressing medication (propylthiouracil) which worked quite well, but you cannot stay on it long term so in January last year I had a total thyroidectomy and I now have to take thyroxine hormone for the rest of my life.

becasue your TSH isn't fully suppressed hopefully your condition is a transient one and will rectify itself in time.

best of luck and keep me posted on your test results
