Background: The harmful effects of hypertension mostly affect the blood vessels, the central nervous system, the retina, the heart, and the kidney, and are frequently detectable using straightforward clinical methods (4). The most significant modifiable risk factor for coronary heart disease, stroke, congestive heart failure, peripheral vascular disease, and end-stage renal illnesses is hypertension. Aims and Objectives: To investigate and classify Renal dysfunction in hypertensive individuals Materials & Methods: Patients with a diagnosis of Hypertension who visited the Medicine Department of Santosh Medical College and Hospital, Ghaziabad, between May 2014 and April 2015 were analysed according to inclusion and exclusion criteria ( May 2014 to April 2015 ). At Santosh Medical College and Hospital in Ghaziabad, Uttar Pradesh, a Case-Control research on renal failure in essential hypertension was conducted with 100 patients as cases and 25 patients as controls. Results: 36 patients (36.0%) had hypertension lasting less than or equal to 1 year, 44 patients (44.0%) had hypertension lasting between 1-5 years, 3 patients (3.0%) had hypertension lasting between 6-1 years, and 17 patients (17.0%) had hypertension lasting between 11-22 years. Conclusion: the frequency of renal impairment differs amongst populations dependent on population characteristics and examination procedures and protocols. Microalbuminuria implies an enhanced renal endothelial permeability and is therefore seen as an early indicator of widespread endothelial dysfunction. Hypercholesterolemia, hypertriglyceridemia, and elevated LDL are all characteristics of essential hypertension.
