I had my thyroid removed 10 years ago. My blood test just came back and it showed my thyroid levels are low, so my doctor just decreased my levothroid from .137 to .125. Is this correct??? Shouldn't my levothroid be increased rather than decreased?

This is always a tricky question Your thyroid level came back too low because you are being over stimulated with synthetic thyroid hormone therefore the doctor needs to give you a lesser dose and recheck it in 6 - 8 weeks. I am not a doctor or a medical professional but I have a underactive thyroid and I believe this is the formula I also know with me they go by my free T4 Hope this helps

GPs usually do a TSH which is thyroid stimulating hormone. If it is high in your blood it means your thyroid medication is too low and If it is low or absent it means your thyroid medication is too high. It is the hormone that stimulates your thyroid to produce more or less thyroid as needed.
The receptionist will read the test and tell you your TSH is low, which means your thyroid medication is really too high. It does get confusing. Thyroid hormone readings are T-3 and T-4. My doctor doesn't do them. He just goes by the TSH readings. Even without a thyroid gland your system produces TSH.
