Objective: The prevalence of T2DM case in 2018 has increased by 10.9%. The majority of T2DM patients often ignore some of the most important conditions to experience complications, which is complications of PDN. This study aims to analyze the dominant factors in PDF patients with hyperglycemia, hypercholesterolemia, and hyperaggregation. Material and methods: This research is a case control study conducted from April to October 2020. The sample is 85 patients who have been confirmed to have PDN by neurologists aged 40 -65. Sampling was conducted at several hospitals in Surabaya with a purposive sampling method. Data analysis was conducted in three stages, namely univariate analysis, bivariate analysis and multivariate analysis. Results: 85 PDN patients who experienced hyperglycemia amounted to 81%, hypercholesterolemia 81%, and hyperaggregation 67%. The dominant factor affecting the three conditions (hyperglycemia, hypercholeterol, and hyperagregation) in this PDN patient was a history of hypertension with a value of p = {(0.012); (0.007); (0.001)} and also a long period of suffering from T2DM with p value = {(0.019); (0.025); (0.041)). Meanwhile, age, gender and regularity for treatment control were not the dominant influencing factors. Conclusion: Suffered for a long time from T2DM and a history of hypertension are the main determinants of peripheral diabetic neuropathy which is along by hyperglycemia, hypercholesterolemia, and hyperaggregation.
