Background:The development of issues in people with diabetes mellitus is predicted by HbA1c. Regular monitoring of the blood lipid profiles of diabetic patients is necessary to determine the best course of treatment based on the patient's age and type of diabetes. Even within the usual HbA1c range, there is a favourable connection between HbA1c and cardiovascular disease in nondiabetic individuals. The purpose of this study was to assess the serum lipid profile and HbA1c levels in type 2 diabetes mellitus (T2DM) and investigate the related variables such as diabetes mellitus duration among type 2 diabetes mellitus patients at a tertiary care hospital in the remote area. Materials and methods: A tertiary care hospital in mumbai, India, provided 124 inpatients and outpatients for the study. For FLP-total cholesterol, HDL, LDL, VLDL, TGL, HbA1c, CBC, urine routine, renal function test, and thyroid function test, information on basic clinical data and blood tests in the fasting state were obtained from qualified patients. Results: The remaining patients had acceptable glycemic control, while 80 patients (64.5%) had poor glycemic control (HbA1c >7.5%). The association between the lipid profile and the duration of diabetes and HbA1c levels showed that triglycerides, total cholesterol, LDL, and VLDL all showed significant positive correlations. Age and HbA1c have a high positive link when other numerical factors like haemoglobin, age, and HbA1c are compared to the duration of diabetes. Conclusion: Our research revealed a strong positive correlation between lipid profiles and HbA1c, suggesting that HbA1c may be used as a dyslipidemia prediction in addition to a glycemic control indicator to help avert complications.
