Hello EMG -
Welcome to the thyroid family.
You are right, your TSH is perfectly normal. Healthy people have TSH of 1.0-1.5.
BUT, your Free T4 and Free T3 are at rock bottom! No wonder you are feeling as poorly as you are. ((hugs)) Most people need their Free levels to be at least
mid-range, but usually 60-80% of range to feel well.
You are, without a doubt, hypothyroid. No one feels well with their Free T4/T3 so low. You would benefit greatly from starting thyroid hormone replacement.
It will require more detective work to figure out why your TSH is so "normal" with those dismal Free levels. Have you had any thyroid antibody testing done? There are some antibodies that can falsely lower or suppress your TSH. These tests are TSI, TRAb and TBII. The antibody tests for Hashimoto's (most common cause of hypothyroidism) are TPO Ab and TG Ab.
HYPOthyroidism = low thyroid hormones (FT4/FT3) & TSH will be high or over range.
HYPERthyroidism = high or over range thyroid hormone levels & low or below range TSH
Unfortunately too many doctors are stuck in the dark ages when it comes to thyroid Dx. They may run the right tests, but ultimately only look at the TSH to make their decision that you are "normal". TSH is a Pituitary hormone and not an accurate indicator of actual Thyroid function.
My thyroid journey was similar to yours. My PCP (now former) also refused me thyroid hormone and instead prescribed, you guessed it, Adderall
. This was the end of a long term relationship with that doctor and the beginning of the hunt for a thyroid savvy one. It took me many months and 4 more doctors before I found my new angel of an MD. She "got it" (my below mid-range Frees) and started me on Levothyroxine. I eventually found out that I have high in range TSI (Thyroid Stimulating Immunoglobins). This explained my falsely low TSH along with low FT4/FT3.
If your current doctor can't see the obvious in your lab work, you will likely never convince him/her. If a doctor can't interpret lab results properly, they probably won't ever prescribe proper treatment either.
My advice to you is to find another doctor. Endos are often the worst for thyroid disease. You should look for a doctor that has a whole body approach. Like Internal Medicine, an Internist or a DO. You could also try searching online for "Top Thyroid Doctors" in your area. Many people here have had success contacting local pharmacies and asking for names of doctors that prescribe dessicated thyroid hormones (ie; Armour) or Cytomel. Not that you will need to take a T3 containing med, but doctors that Rx these meds are far more thyroid savvy.
Hang in there. Keep searching for a new doctor until you find one who will give you the treatment you need and deserve. Please keep us updated.
