Suggest Treatment For Elevated Thyroid Peroxidase
Thyroid
Detailed Answer:
I follow what you are saying.
Thyroid matters can be complex for the non-expert.
Your doctor has done what I would have done as well.
Even though your antibodies are positive, the fact that the TSH is normal it means that up until now the thyroid antibodies have not yet fully damaged your thyroid gland to an extent where it is not making enough thyroid hormone.
So the normal TSH indicates that your thyroid gland is making adequate amounts of thyroid hormone at the present time. And so thyroxine is not necessary at the moment.
Furthermore, sometimes thyroid antibodies can be 'false positive' ie they test positive in the blood test but the individual does not really have Hashimoto's (thyroiditis). In such cases too, treatment with thyroxine is inappropriate.
However this occurs in a minority of the cases.
So the best way to know if you truly have Hashimoto's thyroiditis is to see your doctor, preferably an endocrinologist regularly who will examine you thoroughly, and order appropriate tests over time, to determine if and when you need treatment with thyroxine.

Detailed Answer:
I understand what you are trying to state here.
There is no known medical or non-medical treatment/ approach to modify the Hashimoto's disease process. So as per current knowledge there is no way to prevent the TPO from attacking the thyroid.
