Mary and Manoj were classmates and good friends. On turning 11, Mary developed a little bulge on the front of her neck Class 7

Mary and Manoj were classmates and good friends. On turning 11, Mary developed a little bulge on the front of her neck. She visited the doctor who gave her medication and asked to take iodine-rich diet. Similarly, a bump was developed on the front of Manoj's neck when he turned 12. However, the doctor told him that it was a part of growing up. According to you, what could be the possible reason for advising Mary and Manoj differently? Class 7

Answer:

  1. Mary: Mary's doctor recommended her to take iodine-rich diet, because the bulge (swelling) on her neck is goitre that is caused by deficiency of iodine. Iodine's deficiency can lead to the enlargement of the thyroid gland, causing a bulge on the neck.
  2. Manoj: Manoj's bump was due to the growth of his voice box as he entered puberty, this is called as the Adam's apple. It causes a bump in the throat and can lead to a hoarse voice as the voice box grows and changes shape.
