28M - Blood work flagged significant thyroid antibody levels - sharing results and looking for similar experiences
Wanted to share my recent test results and get some perspective from people who've been through this.
Family history: My mom has been on hypothyroid medication for 20+ years, so this has been in the back of my mind.
My symptoms (that prompted me to finally get tested):
- Fatigue and brain fog that's been going on for a while, hard to pin down how long
- Hair thinning over the last ~2 years
- Uncertain if these are thyroid related or something else entirely
- I did have a really heavy weight period about 3 years ago (I was up from my current weight of ~230 up to like 242. My face looked really really heavyset, first time ever in my life. I definitely need to be more active, office work isn't great for me. Looking long term I want to be closer to 200lbs)
| Test Type | Reading | Normal Range |
|---|---|---|
| TSH (Thyroid Stimulating Hormone) | 4.65 (High) | 0.40 - 4.50 mIU/L |
| Free T4 | 1.4 | 0.8 - 1.8 ng/dL |
| T3, Free | 3.6 | 2.3 - 4.2 pg/mL |
| Thyroid Peroxidase Antibody (TPO) | 511 (High) | < 9 IU/mL |
| Thyroglobulin Antibody | 82 (High) | < 2 IU/mL |
Not knowing much going in, seeing TPO at 511 and Thyroglobulin at 82, both ~40x+ over the upper limit of normal definitely made me raise my eyebrows. Free T3 and T4 are still largely within range so my thyroid is apparently still compensating for now.
Where things stand: My PCP acknowledged the results but feels the TSH isn't high enough to treat yet. We have a retest scheduled for ~3 months out. I have been not going to the doctor regularly the past 3-4 years so I do understand that getting some actual medical history / testing history is valuable. Make sure its not just a one off. I've also started Vitamin D supplementation as that came back insufficient at 26 ng/mL.
I'm not here to self diagnose and I'm actively trying not to fall down the Google / AI rabbit hole. Just genuinely looking for perspectives from others, especially men in a similar age bracket, who've had comparable antibody numbers and can speak to what their experience navigating the specialist system was like, particularly in the US.
What should I expect?
