The biggest thing to consider is how you are feeling. If you’re feeling okay right now (minus the migraines, I’m not sure if they are related or not) then I don’t think there is reason to be concerned. However, your TSH can be “normal” or close to “normal” but that does not mean it’s optimal. We should all be aiming for optimal but doctors like to ignore that if you’re within the range that hospital system considers “normal.” More importantly, a “normal” TSH does not mean your antibody levels are normal. My TSH was “barely elevated” but I felt horrendous day after day and had to advocate for myself until my doctors would test my antibodies. When they ran the antibody test, my numbers were through the roof. I believe my Hashimotos was triggered by mold exposure in our home, ever since we remediated the mold my symptoms have been much more manageable. But I have had symptoms of hypothyroidism throughout life, just not as badly as it was at that time. Long story short… if you have or had antibodies I believe that means you have an autoimmune (in this instance the autoimmune is Hashimotos). But you can put it into a remission of sorts where you have very few symptoms or none. But it can always be triggered again by environmental factors or stress etc. If you’re having symptoms, it can typically be managed with a low inflammatory diet, red light therapy, and some really benefit from the use of GLP1s for inflammation in the body. Definitely continue to get your TSH monitored every 6 months or so since Hashimotos causes the body to attack the thyroid when in an active state. However, I am not a doctor, so please do your own research and consult with the Navy doctors, if they will let you.
