What this all means is that your thyroid gland will produce less and less hormone. In order to feel well, you will have to take thyroid hormone to make up for the lack of hormone produced by your body.
The trick is to get on the proper dose and keep up with the reduction over time of the thyroid gland loss of production so that you feel well.
Please post the reference ranges for your T3 and T4. Ranges vary lab to lab, so you have to post them with results. Also, do they say they are FREE T3 and FREE T4?
TPOab is elevated, which means you most likely have Hashimoto's thyroiditis, which is an autoimmune disease and the most prevalent cause of hypothyroidism.
Once you develop symptoms, if you haven't already, you will have to take replacement hormones for the rest of your life, much like a diabetic has to take insulin.
Hashi's is treatable, as described, but not curable.
