Diabetic foot ulcers (DFUs) and diabetic peripheral neuropathy (DPN) are severe complications in type 2 diabetes mellitus (T2DM). Selenium (Se) is an important element with antioxidant properties, which is crucial for human homeostasis. In this narrative mini review, we summarise the evidence on the potential association of Se with DPN and DFUs. Generally, in most of the limited number of studies, serum Se levels were significantly lower in subjects with DPN or DFUs. In addition, one study demonstrated that urinary Se levels were lower in the DPN group. Nevertheless, further investigations are needed to confirm these preliminary findings.
