Introduction – Diabetes is a chronic condition whose prevalence is increasing in France and worldwide. Among its complications, diabetes-related foot ulcers represent a major public health challenge. While the clinical aspects are well documented, the lived experience of those affected remains less described. Materials and Methods – A qualitative study was conducted at Diabète LAB (French Federation of Diabetics) using semi-structured interviews (n=9) conducted by telephone with adults living with diabetes who were being treated for a diabetic foot complication. The approach was inductive, inspired by grounded theory, with thematic analysis. Results – Four main themes emerged: loss of mobility leading to dependence and social isolation; emotional impact, including uncertainty and the specter of amputation; the role of social and territorial determinants (home modifications, access to a healthcare network); the decisive influence of interactions with healthcare professionals, which can provide support or exacerbate anxiety. Discussion-Conclusion – Diabetes-related foot ulcers have significant and socially differentiated psychosocial consequences. A care approach that more fully integrates therapeutic education, a clear care pathway, social assessment, and support for family members could improve patients’ experience and adherence to care.
