MATERIAL AND METHODS: Total 60 patients were included in this study with the diagnosis of euthyroid syndrome with suggestive of Non-thyroidal Illness. AIM: The main objective of this study is to study clinical profile sick euthyroid syndrome in Non-thyroidal Illness. As there is progress in illness gradual development of a more complex syndrome associated with low levels of T3 and thyroxine (T4). Although by definition these abnormalities are not related to intrinsic diseases of hypothalamus-pituitary-thyroid axis though rather represent imbalances in thyroid hormone production, metabolism, and action. This can be representing especially in in critically ill patients, particularly those admitted to intensive care units. In the 1970s initially described low T3 (triiodothyronine) syndrome, known as the euthyroid sick syndrome or the nonthyroidal illness syndrome (NTIS).

Abnormal findings on thyroid functions tests which occur in the setting of a non thyroidal illness (NTI) without preexisting hypothalamic-pituitary and thyroid gland dysfunction. INTRODUCTION: Sick euthyroid syndrome is also known as low triiodothyronine (T3) syndrome or non-thyroidal illness syndrome which is characterized by alterations in the levels of thyroid hormones in the absence of any disorder related to thyroid gland or hypothalamic-hypophysial axis. of General Medicine Vedanta Institute of Medical Sciences Dahanu Palghar, Maharashtra.
