Chandigarh, October 20:- World Iodine Deficiency Day, observed every year on October 21, highlights the importance of iodine in normal growth, development and overall health. The day aims to raise awareness about iodine deficiency and promote the use of adequately iodized salt as a simple preventive measure.
Iodine is an essential micronutrient required by the thyroid gland to produce hormones that regulate metabolism, body temperature, growth and brain development. Since the body cannot produce iodine, it must be obtained through dietary sources. Pregnant women, infants and young children are particularly vulnerable to iodine deficiency.
Speaking on the occasion, Prof. Sanjay Bhadada, Head of the Department of Endocrinology at PGIMER, Chandigarh, said that although iodine is required only in small quantities, it plays a vital role in maintaining health. Its deficiency can lead to thyroid enlargement (goitre), hypothyroidism and, in severe cases, impaired physical and cognitive development. Adequate iodine intake during pregnancy and early childhood is particularly important for the proper development of a child's brain and nervous system.
Prof. Bhadada emphasised that regularly consuming adequately iodized salt is one of the most effective ways to prevent iodine deficiency. People should check whether their salt is iodized and store it in a covered container in a cool, dry place. Adding salt towards the end of cooking, wherever possible, can also help reduce iodine loss.
He clarified that using iodized salt does not mean increasing salt consumption, as excessive intake can increase the risk of high blood pressure and cardiovascular diseases. People who consume adequate amounts of iodized salt generally do not require additional iodine supplements without medical advice.
The Department of Endocrinology stressed the importance of public awareness, timely diagnosis and appropriate medical consultation to prevent iodine deficiency disorders and protect thyroid health.
On the occasion, PGIMER reiterated the need to promote informed dietary practices and ensure access to iodized salt to safeguard the health of future generations.
