What exactly causes the production of auto antibodies
is not exactly known but the theory suggests that besides pregnancy
and a strong family history are the biggest risk factors for causing auto immune thyroid disease.
If your close relative is suffering from autoimmune thyroid disease
,then you are 5-10 times more likely to get it as compared to the average normal person.
You are having slightly high levels of thyroid antibodies and the treament depends upon your symptoms.If you are symptomless,then no need to start the treatment and just a periodic check up is required.
