Patient's Query

Hi doctor,

I was diagnosed with Hashimoto's four years ago and maintained on NDT. All the tests are within the normal range although borderline till now. My result shows extremely low TSH 0.036 µIU/mLand FT4 of 0.28 ng/dL and extremely high FT3 of 11 ng/dL. My cortisol and ACTH are also extremely low. My TPO is less than 1 µIU/mL. What to do?

Welcome to icliniq.com. Your answer is present in your question itself. Your TSH (thyroid stimulating hormone) is extremely low and hence it would mean hyperthyroidism. However, radioactive thyroxine uptake is a test that would be better to be performed to check the performance of the gland. Also, you will need urgent treatment since you can go into a thyroid storm (a life-threatening complication of hyperthyroidism) anytime, which is an emergency. Consult an endocrinologist as soon as possible for physical evaluation and get the necessary steps. They might also have to remove your thyroid and parathyroid either partly or completely to keep it under control. If your TSH and ACTH - adrenocorticotropic hormone is also low, it means a pituitary gland problem. You should also get an MRI scan to detect abnormalities. Take care and get well soon.

Same symptoms don't mean you have the same problem. Consult a doctor now!
