Background: A protein tolerance test can be highly helpful in selecting individuals who are most likely to benefit from an aggressive intervention by detecting incipient renal failure in those with normal GFR and serum creatinine values. This is crucial when assessing high-risk individuals including diabetics, people who have just undergone a kidney transplant, and people with polycystic kidney disease. PTT can be used to accurately predict the prognosis of a progressing renal disease and to evaluate the borderline renal donor. To demonstrate the value of the tubular stress test, standardisation and additional research are still needed. The purpose of this study was to examine the evolution of renal dysfunction with age and the duration of Type 2 Diabetes mellitus, as well as to assess the protein tolerance test as a marker for early renal impairment in Type 2 Diabetes mellitus. Method: From March 2022 to February 2023, participants in this clinical trial were outpatients at the DMCH in Laheriasarai, Bihar. 208 instances altogether were split into two groups. In this study period, 108 cases in the study group and the remaining 100 cases in the control group were included. The study included people with Type 2 diabetes mellitus. For comparative purposes, 100 healthy, age- and sex-matched controls free of diabetes or its consequences were also included in the study. Results: The prevalence of renal failure was found to be higher in individuals older than 60 years, at 179 (86.05%), compared to 33 (15.86%) in the group of patients who were 51–60 years old and 17 (8.17%) in the 41–50-year group. In contrast, in patients with renal dysfunction, 35 (16.8%) were found to have renal risk, and 43 (20.7%) had renal failure. It was discovered that normal working kidney would be able to lower urine protein after protein tolerance. In contrast to cases of renal failure, where eGFR decreased following protein tolerance, it was shown that kidneys with normal function responded to protein tolerance by increasing eGFR. In contrast to cases of renal failure, blood creatinine levels increased after protein tolerance good working kidney increased GFR. Renal failure risk is increased by Type II diabetes mellitus for an extended period of time. Conclusion: Compared to patients with normal renal function or mild renal dysfunction, patients with renal failure exhibited more persistently elevated blood creatinine and sustained decreases in GFR.
