If a patient with iodine deficiency develops resistance to TSH, which consequence follows regarding thyroid hormone production?

💡 Explanation

TSH resistance means the thyroid doesn't respond normally to TSH stimulation. Because iodine deficiency limits thyroid hormone synthesis and TSH resistance further impairs the thyroid's ability to produce T3 and T4, therefore both hormones will be diminished rather than either hormone production increasing.
