Epidemiology of Iodine Deficiency Disorders in North-Eastern Part of Karnataka, India

The north-eastern part of Karnataka lies on the Deccan Plateau of the South Indian Peninsula, characterized by black soil. This region is known for its mineral resources, including a gold ore mine in Hatti (Raichur District), an iron ore mine in Toranagallu (Bellary District), and uranium deposits in Gogi (Yadgir District). However, the soil in this area is deficient in iodine, leading to iodine deficiency disorders such as goiter and hypothyroidism. More than 80,000 cases of these disorders have been reported in the region, along with a few cases of Hashimoto's thyroiditis and Graves' disease. The younger age group is predominantly affected, with a higher prevalence in females compared to males. As a result, hypothyroidism contributes to pregnancy-related complications and obesity in women. Early detection is possible due to the visible swelling in the neck, prompting patients to seek medical attention. Timely diagnosis and appropriate treatment can reduce goiter size, restore the body to a euthyroid state, and alleviate symptoms.
