WebBut, if you have an autoimmune response, your thyroid gland may become overstimulated, causing it to generate an abnormally high quantity of T4 and T3. This may result in a breakdown of the feedback loop because the quantity of circulating thyroid hormones continues to be high even while the amount of TSH and TRH that is generated is lowered.
