Thyroid Dysfunction Among CKD Patients — A Retrospective Analysis of Prevalence and Hormonal Correlations

Background: Chronic kidney disease (CKD) is frequently associated with thyroid dysfunction, yet the prevalence and hormonal patterns remain inadequately characterized in the Indian population. This study aimed to determine the prevalence of thyroid dysfunction among CKD patients and evaluate correlations between thyroid hormone levels and renal function parameters. Methods: A retrospective cross-sectional study was conducted over 24 months (January 2023 to December 2024) at a tertiary care hospital. Medical records of 168 CKD patients (stages 3-5) were analyzed. Demographic data, renal function tests (serum creatinine, blood urea, eGFR), and thyroid profiles (TSH, FT3, FT4) were extracted. Thyroid dysfunction was classified based on standard reference ranges. Statistical analysis included Pearson correlation, independent t-tests, ANOVA, and multiple regression analysis with significance set at p
