Hello, this is Dr. David. I have read your question and I'm ready to help.
how do you know your levothyroxine is not working
what is your most recent TSH and T3 and T4 level?
Customer: replied 2 years ago.
it is 0.13 not even on the charts I know it can go up to 4.5. It has been like this for about 3 months. Could it be a goiter? cancer? My dr. suggested a mri but i have extreme chlostraphobia so i cannot Even taking a sedative before didn't help. I am very concerned, hair falling out extreme fatigue, my mother had a goiter removed when she was younger and always had thyroid problems, is it inherent?
Customer: replied 2 years ago.
what kind of tests other than mri can I get to see what is the cause?
Expert:  Dr. David replied 2 years ago.
TSH of 0.13 means you are having too much thyroid hormone in your system
you want your TSH levels between 0.3 and 3.0
TSH levels of below 0.3 mean you are hyperthyroid or have too much thyroid hormone in your system.
the best way to look at your thyroid gland is with a thyroid ultrasound.
fatigue can be caused by other causes than thyroid
you need your iron and B12 and vitamin D levels checked to be sure.
low levels of iron and biotin can cause hair loss as well.
I suggest you see an endocrinologist to get blood testing to check for anti thyroid antibodies as well
not all thyroid conditions are hereditary.
let me know if you have questions.
