Can someone help me with a question?

[Guest guest]

Hi. I have a question regarding labs. My T4.Free, T4.Total and

T3.total are normal range, but my TSH is 0.06 compared to normal

values-0.49-4.67. I have the eye disease in one eye and my doctor

referred me to an Endo. I am on no meds because he said these

results don't merit it. Can someone help me to understand.

Hi Donna,

When thyroid hormone levels are normal and TSH is suppressed, you have a

condition of subclinical hyperthyroidism.

This means that your pituitary recognizes that you have more than enough

thyroid hormone for your body's needs. So it stops releasing the regulatory

hormone TSH. Normally, TSH regulates your thyroid hormone levels, and it's

released in constant little pulses. Normally, TSH orders your thyroid cells

to produce thyroid hormone.

But seeing you don't need its help, the pituitary slows down TSH production.

The reason you have enough thyroid hormone is because your immune system is

producing thyroid antibodies known as TSI that act in place of TSH, causing

the excess thyroid hormone production. These antibodies also contribute to

the eye symptoms.

Subclinical conditions aren't usually treated because they often resolve on

their own, and because treatment intended to lower thyroid hormone levels can

make you hypothyroid.
