Introduction: There are two mechanisms proposed for the greater urinary albumin excretion (UAE) in patients with essential hypertension: increased glomerular hydrostatic pressure or increased selectivity of the glomerular basement membrane. In hemodynamic mechanism regulation of the glomerular hydrostatic pressure is regulated by the relative vasoconstriction vasodilatation of the afferent and efferent glomerular arterioles. Hypertension is one of the major public health problems in the world. In India the prevalence of hypertension is about 25% in urban and 10-15% in rural, adult population as compared to west which is 30%. Essential hypertension is responsible for producing clinical proteinuria and a significant reduction in renal function in 5-15% of patients. Several studies have shown that proteinuria and microalbuminuria are independent predictors of cardiovascular morbidity and mortality in patients with hypertension. Some data suggest that reduction of albumin excretion rate reduces the risk of adverse renal and cardiovascular events (CVEs).
 Material and Methods: Patients, who had high blood pressure based on JNC 8 (Joint National Commission 8) criteria during three subsequent visits to the outpatient clinic and a creatinine clearance greater than 80 ml/min/1.73 m2, were included in the study. A total of 546 essential hypertensive patients whose BP was> 140/90 mm Hg in nondiabetics and BP >130/85 mm Hg in diabetic patients were included in the study. Blood pressure monitoring was done according to the WHO guidelines. Demographic data, age, sex, weight, associated cardiovascular disease, albuminuria, and clinical parameters were all recorded. All routine biochemical tests and microalbuminuria tests were performed by the laboratory. Blood and urine creatinine were measured using an autoanalyzer.
 Results: There were 322 (58.97%) male and 224 (41.02%) female included in the study. Left ventricular hypertrophy was observed in 267 (48.9%) of the patients, retinopathy was seen in 54 (9.89%) and microalbimunira was observed in 297(54.4%) of hypertensive patients. 129 (23.63%) were smokers. Statistical significance was observed renal parameters except serum uric acid levels.
 Conclusion: Prevalence of microalbuminuria in hypertensive patients warns that screening for microalbuminuria is essential for intervention and prevention of complications and renal diseases. Also it is necessary to screen the patients for early nephropathy to halt the disease progression.
