Question

Write brief statements explaining the following: People living in hilly region usually suffer from simple goitre.

Answer 1

In hilly regions, the soil is deficient in the salts of iodine. Thus, the food chain lacks iodine. Hence, food grown in hilly regions is also deficient in iodine. People eating such food suffer from a deficiency of iodine, which leads to undersecretion of thyroxine. This causes goitre. Therefore, people living in hilly regions usually suffer from simple goitre.
