Background:  Deficiency of thyroid hormones causes red cell disorder in our body. Anaemia is a common sign. Hypothyroid disorder patients have a decreased RBC mass due to reduction plasma volume. On routine examination such as hemoglobin estimation it may be missed because of increased RBC mass is observed in other causes of anaemia. Thyroid hormones have significant effects on renal haemodynamics and suspected cardiovascular diseases.

1. To know the effect of SCH on 1) erythrocyte indices (HB, HCT, MCV & RDW-cv)
2. Renal function parameters( urea, creatinine and e-GFR)
3. Cardiovascular parameters (triglycerides, total cholesterol, HDL, LDL )
4. Inflammatory marker i.e CRP

In our study ie hospital based observational study for one year. HB, HCT, MCV, RDW, FT4, TSH, TOTAL CHOLESTEROL, TRYGLYCERIDES, LDL, HDL, CRP, UREA, CREATININE were estimated and eGFR was calculated using modification  of diet in renal disease study equation. Higher RDW measurement have been strongly associated with low HDL cholesterol and an inverse and graded association between renal function was reported in our study.
