: The most prevalent form of the disease, type 2 Diabetes Mellitus is often asymptomatic in the early stages and it may remain undiagnosed for many years.The insulin resistance in the liver leads to failure of the hyperinsulinaemia to suppress the gluconeogenesis, which increases fasting glucose levels and decreases Postprandial hypertriglyceridemia results in a proatherogenic environment which leads to atherosclerosis and macrovascular complications in type 2 diabetes mellitus. It is believed that atherosclerosis is a postprandial phenomenon with respect to lipids, as we are in the postprandial state for most of the day. Increased glucose production in the liver occurs early in the course of diabetes, and it is likely in skeletal muscles after the onset of the insulin secretory abnormalities and the insulin resistance Due to the insulin resistance in the adipose tissue and obesity, the free fatty acid (FFA) flux from the adipocytes is increased, which in turn leads to an increase in lipid [very low-density lipoprotein (VLDL) and triglycerides] synthesis in the hepatocytes. This is responsible for the dyslipidaemia which is found in type2 diabetes mellitus [elevated triglycerides, reduced HDL, and increased low-density lipoprotein (LDL) particle.Individuals with type 2 diabetes mellitus are at increased risk of developing microvascular and macrovascular complications. Increased postprandial glucose (PPG) concentrations contribute to suboptimal glycemic control. : To correlate fasting and postprandial dyslipidemia with macrovascular complications of diabetes.: This is a cross-sectional study, wherein written informed consent was taken after giving detailed information to the participants regarding the study. Patients who were in the age group of 35-65 years, admitted in the Department of Medicine, RRMCH from November 2017 for next 18 months with Diabetes Mellitus who met a predefined inclusion and exclusion criteria were studied. The study was initiated after obtaining clearance from the institution's ethical committee.: IHD changes were found in 8 cases and 3 controls, LVH by voltage criteria was found in 15 cases and 8 controls. IHD changes found in cases and controls are 16% and 6% respectively. LVH changes found in cases and controls are 30% and 16% respectively.Abnormal 2D Echo findings in our study were mainly IHD and LVH. The occurrence of IHD was more in cases compared to controls with statistical significance(p&#60;0.05).Peripheral vascular disease in our study was found in 25 patients i.e.25% of the study group. In cases, it was found in 20 patients and in controls, it was found in 5 patients i.e. 40% and 10% respectively. The occurrence of PVD was more in cases compared to controls with statistical significance(p&#60;0.05).Stroke in our study is found in 7 patients i.e. 7% of the study group. In cases, it was found in 6 patients and in controls, it was found in 1 patient i.e. 12% and 2% respectively. : It could be said that there is an increase in the occurrence of postprandial dyslipidemia with increasing age, irregular treatment, increase in HbA1c, FBS ,PPBS and with the past history of HTN, CVA, PVD and IHD.All macrovascular complications (IHD, CVA, PVD) were found more in the case compared to controls with statistical significance. So it could be said that there is an increase in the occurrence of macrovascular complications with an increase in postprandial dyslipidemia.
