Solution
People living in hilly regions often suffer from simple goitre because the soil and water in these areas are typically iodine-deficient. Since iodine is essential for the production of thyroid hormones, this chronic deficiency leads to the enlargement of the thyroid gland, known as simple goitre, as the gland attempts to compensate for the lack of iodine.
