Introduction: Cirrhosis is an advanced stage of liver fibrosis that is accompanied by distortion of the hepatic vasculature. It is the histological development of regenerative nodules surrounded by fibrous bands in response to chronic liver injury. Objectives: The study was intended to assess serum Triiodothyronine (T3), Thyroxine (T4) levels and Thyroid Stimulating Hormone (TSH) on the basis of Child Pugh Score in patients with Liver Cirrhosis. Methodology: 100 clinically diagnosed cases of Liver Cirrhosis patients were enrolled for the study. Estimation of Thyroid Hormones were performed. Statistical evaluation was done for analysis of the results. Result: The study documented a significant decrease in T3 levels (P= <0.0001), a non-significant increase in T4 levels (P=0.997) and a slightly significant increase in TSH levels (P=0.034) on the basis of CP Score. Conclusion: The patients with liver cirrhosis have significantly decreased levels of T3 with increased CP Score. The routine liver enzymes like AST, ALT and ALP may be unable to predict the risk of development of liver cirrhosis specially in the early stages. Therefore, screening of serum T3 levels is strongly recommended in patients with early-stage liver diseases like ALD, NAFLD, NASH and CLD.
