Question

Identify the non-infectious disease from the following:
1. Syphilis
2. Rabies
3. Goiter
4. Cholera

Answer 1

Correct Answer - Option 3 : Goiter

The correct answer is Goiter.

• Goitre is a disease in which swelling occurs in the Thyroid gland present in your neck.
• Thyroxine is a hormone that is secreted into the bloodstream by the thyroid gland.
• This hormone plays a vital role in the proper functioning of the Heart, Digestive system, metabolic activities etc.
• Iodine is the main component of the Thyroxine hormone and deficiency of the former leads to deficient production of the latter by the thyroid gland.
• The thyroid then works extra hard to produce the requisite Thyroxine hormone which leads to swelling in it and hence Goiter.
