Question

Effects of high TSH on baby

Answer 1

High Thyroid Stimulating Hormone in a child could result in two major issues, each one dependent on the end effect of the excess TSH. If, the TSH causes an increased concentration of T3/T4, then the most obvious effect would be hyperthyroidism. This is extremely rare, accounting for ~1% of hyperthyroidism cases and is almost always a sign of a clinically active adenoma. Hyperthyroidism could cause low weight, difficult weight gain, excessive hunger, diplopia, Dalrymple sign, tremors, fatigue, excessive sweating, etc. High TSH low T3/T4 concentration would be indicative of cretinism, hypothyroidism, or Hashimoto's thyroiditis.
