Introduction 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. glycogen storage by the liver in the postprandial phase. 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) particles. Individuals with type 2 diabetes mellitus are at increased risk of developing microvascular and macrovascular complications Materials and Methods This was a cross-sectional study of newly diagnosed type 2 DM patients in the Department of Physiology, Shadan Institute of Medical Sciences Teaching Hospital & Research Centre. Demographic, clinical and laboratory data were extracted from the case notes of eligible patients and analyzed using STATA version 14. Continuous variables were presented as mean ± standard deviation (SD), or median and interquartile range (IQR) while categorical variables were as frequencies and percentages. Student t and chi-square tests were used to test for association at p < 0.05. Results The study included 160 diabetic patients to evaluate the significance of postprandial dyslipidemia. Patients were categorized based on their glycemic status, lipid profiles, and postprandial lipid levels. Postprandial dyslipidemia, characterized by elevated triglycerides and reduced HDL-C levels, was a significant finding in this study. These abnormalities were more pronounced in patients with poor glycemic control, highlighting the importance of postprandial lipid monitoring and its potential role in managing cardiovascular risk in diabetic patients. Conclusion Postprandial dyslipidemia is prevalent among diabetic patients and is significantly associated with poor glycemic control. Monitoring postprandial lipid levels could be essential in managing cardiovascular risk in this population
