My TSH levels are normal, but I still feel awful. What’s wrong with me?
So your thyroid-stimulating hormone is normal, but you still feel awful even though your doctor says, “You know you’re doing great, and we’re giving you the right medication. You’re normal, it can’t be your thyroid.” I want you to know that it definitely can be.
And Here’s How: Reverse T3
Your thyroid-stimulating hormone can be normal, but you can have a really high level of something called Reverse T3. Reverse T3 is an inactive form of T3.
So there’s T3 and reverse T3. T3 is the active version. Reverse T3 actually binds up the receptors that T3 would go into and stops you from activating. So although you have a normal amount of T3, too much or a higher percentage of it is going into reverse, and that’s inhibiting your thyroid from working. So yeah, you have a normal thyroid-stimulating hormone, but you still can’t use your thyroid. So absolutely, it’s not all in your head.
