Dyslipidemia one of the major cardiovascular modifiable risk factor, is characterized by high levels of plasma triglycerides (TG) and low-density lipoprotein cholesterol (LDL-C) particles, and low levels of high-density lipoprotein cholesterol (HDL-C) and insulin resistance. It increases the risk of macrovascular and microvascular complications in type 2 diabetes. Hence the present study was planned for evaluation of Prevalence of the Dyslipidemia in Bihar Patients Diagnosed with the Diabetes. The present study was planned in department of General Medicine, Patna Medical College and Hospital, Patna, Bihar, India. The 60 patients were enrolled in the present study. The patients were divided in two study groups as diagnosed with diabetes and another are non-diabetic patients. The biochemical parameters like Fasting glucose level, Glycated haemoglobin (HbA1c), Total cholesterol, Triglycerides, High Density Lipid, and Low Density Lipid were estimated. The diabetic patients had elevated serum total cholesterol, elevated triglyceride (triacylglycerol) and slightly elevated low density lipoprotein and reduced levels of high density lipoprotein indicating that diabetic patients were more prone to cardiovascular diseases. The data generated from the present study concludes that lack of knowledge among people in developing countries on dyslipidemia which can be effectively managed in type 2 diabetes patients by life-habit modifications in combination with strict adherence to pharmacological interventions. There remains the need to impart awareness on the dosage, potential side effects and benefits of continuing uninterrupted medication of the prescribed medications in order to optimise the management of dyslipidemia.
