alleryExcess production of growth hormone before adulthood mainly causes:
ADwarfism with short height
BGigantism with great height
CGoitre in the neck region
DDiabetes with high sugar
Answer & Solution
Correct answer: B. Gigantism with great height
1. Growth hormone controls height growth during childhood.
2. **Too little** growth hormone → dwarfism; **too much** growth hormone before adulthood → **gigantism**.
3. Goitre is a thyroid disorder; diabetes is from insulin deficiency.
4. Hence excess growth hormone in childhood causes gigantism.
