World Iodine Deficiency Day, also known as Global Iodine Deficiency Disorders Prevention Day, is observed annually on the 21st of October.
The day aims to raise awareness about iodine’s essential role in maintaining good health and emphasize the consequences of iodine deficiency. This document outlines the importance of iodine in daily nutrition and its crucial significance in preventing iodine deficiency disorders.
Iodine is an essential component of the thyroid hormones thyroxine (T4) and triiodothyronine (T3), which regulate metabolism and are crucial for fetal and infant development. In foods and iodized salt, iodine exists in several forms, including sodium and potassium salts, inorganic iodine (I2), iodate, and iodide.
Iodide, the most common form, is quickly absorbed in the stomach and used by the thyroid for hormone production. Most excess iodide is excreted through urine. Iodine deficiency has multiple adverse effects on growth and development and is the most common cause of preventable intellectual disability in the world. Iodine deficiency disorders result from inadequate thyroid hormone production secondary to insufficient iodine. During pregnancy and early infancy, iodine deficiency can cause irreversible effects.
