Introduction: Diabetic peripheral neuropathy (DPN) is a frequent but under-recognized complication of diabetes mellitus (DM). Loss of protective sensitivity (LPS) is an important feature of DPN, potentially leading to ulcers and amputations if not detected early. Objective: To determine the prevalence of LPS in individuals with type 2 diabetes (T2DM) in a tertiary healthcare service, correlating it with alterations in nerve fibers, comorbidities, and other risk factors. Methodology: A cross-sectional, exploratory, and descriptive study with a quantitative approach carried out on T2DM patients. Data was collected through anamnesis, clinical examination of the feet, medical record analysis,and by testing various sensitivities. Results: 76 people took part, with an average age of 65.4 years (60.5% women). The average time since DM diagnosis was 17.6 years, and the average glycated hemoglobin was 9.4%. LPS was detected in 15.8% (n=12) of the participants, with 58.3% of whom were men, 58.3% obese, 91.7% hypertensive, 75.0% with diabetic kidney disease (DKD), 33.3% with retinopathy, 50.0% ex-smokers, and 83.4% using insulin. Conclusion: Although few people were affected by PSPP, the data from this study corroborated the literature regarding the association of obesity, arterial disease, DKD, retinopathy, smoking and insulin use with LPS. This reinforces the importance of periodic foot examinations in T2DM patients.
