Question : i have been on levithyroxin for several years. the dosage goes between 100mg to 125mg and
back again. After a recent blood test, the new dosage is 88mgs. does that mean my thyroid
is working better and I need less or?

Brief Answer:
Thyroid dose
Detailed Answer:
I follow what you are asking.
As one grows older, the dose requirement of levo thyroxine goes down by 10 to 15%
The reason for this is that as we grow older, we tend to lose muscle mass. So a lower dose of levo thyroxine tends to suffice.
Sometimes when people lose weight, the dose requirement comes down for similar reasons.
The most important thing is to keep the TSH and Free T4 in target range. Discuss your goals with your endocrinologist
