Background: Iodine (I) is a trace element that is required by both humans and animals. It can be found in a variety of chemical forms, including iodine, iodide (I), and iodate (IO3). It is widely distributed across the earth's ecology, with a concentration in the oceans. Iodine entered the natural cycle from the ocean, the atmosphere, and rainfall, as well as from rainfall into streams and rivers. Iodine is absorbed as iodide in human nutrition. Iodine is a necessary micronutrient and a component of thyroid hormones. Fish and seafood have a high iodine level. The amount of iodine in soil and drinking water varies depending on where it comes from. Iodine shortage produces a variety of negative health consequences, which are referred to as iodine deficiency illnesses (IDD). These conditions are caused by a lack of iodine, which causes insufficient thyroid hormone production.
 Aim: The aim of this study is to characterize the iodine deficiency disorder by biochemical and clinical assessment and to correlate the iodine status with thyroid disorder(s) in adults.
 Material and Method: The samples for this investigation were taken from patients at the Department of Endocrine Surgery. This study comprised a total of 100 hundred goiter patients, who had their urinary iodine excretion and thyroid hormone levels examined. For all goiter patients, the grading of goitre was established using the WHO/UNICEF/ICCIDD approved criteria. TSH, Free T4, Free T3 by using ELISA Method using commercial kits. Anti-microsomal antibody (AMA) or Thyroperoxidase antibody (TPO-Ab) by using ELISA Method using commercial kits. Anti-thyroglobulin antibody (ATG) estimated by using ELISA Method using commercial kits.
 Results: The data for each group were presented as Median and inter quarter range (IQR) The median and IQR of Urinary iodine excretion of the hypothyroid, hyperthyroid and Euthyroid goiter subjects were respectively and there was significant difference in the median urinary iodine excretion. The median and IQR of Urinary iodine excretion of the thyroiditis, thyrotoxicosis, cancer of thyroid and benign goiter respectively and there was significant difference in the median urinary iodine excretion.
 Conclusion: For ages, endemic goitre and cretinism have been recognised as public health issues, and iodine deficiency is thought to be the leading cause of preventable mental retardation. Most countries now include iodine deficiency control as part of their national nutrition policies. To eliminate iodine deficiency, several therapies with high efficacy have been employed, including iodized oil capsules (IOC) and universal salt iodisation (USI). Although some progress has been made, efforts to eliminate this devastating health problem must be hastened. Not only should iodine deficiency be monitored, but so should excessive iodine intake, as this is a problem in various areas, including the camps.
