I am very confused about what's wrong with me. I am a runner and noticed about 2 weeks ago that my heart rate was super high when I was running and my resting heart rate was also incredibly high. I ran a marathon about 5 weeks ago and didn't have any problem. This is what prompted me to go to the dr. My primary care suspects hashitoxicosis based on the following labs...TSH 0.01 mIU/L (norm 0.4-4.5), T3 Uptake 34 (norm 22-35%), Thyroxine, free, direct 2.01 ng/dl (norm 0.8-1.8), Thyroid Peroxidase (TPO) 485 IU/ml (norm ), Thyroglobulin AB 28 IU/ml (norm less than 20). My ultrasound showed a thyroid at the upper limits of normal in size with heterogeneous echogenic texture. Also, my WBC's are very low 1.7 Thousand/ul (norm 3.8-10.8).
Again the main symptom has been low excercise tolerance....because my heart rate goes through the roof when I try to run or lift weights. I also found myself feeling short of breath on stairs. I've have had some other symptoms of hyperthyroidism, but the increased heart rate is what's been bugging me.
I'm just wondering if these are enough tests to diagnose hashitoxicosis. What about Graves disease?
