A Case Report on Diabetic Foot Ulcer in a Patient with Long-Standing Uncontrolled Diabetes Mellitus

Diabetic foot ulcer (DFU) represents a major chronic complication of diabetes mellitus (DM) and is a significant public health issue globally, particularly in resource-limited settings. DFUs accounts for a substantial proportion of diabetes-related hospital admissions and are the leading cause of non-traumatic lower limb amputations. This case report presents the comprehensive management of a 60-year-old female with longstanding, poorly controlled type 2 diabetes mellitus who developed a foot ulcer due to peripheral neuropathy and trauma. The ulcer, initially neglected and self-treated, became infected and resulted in sinus formation. Through a coordinated, multidisciplinary approach—encompassing pharmacological intervention, surgical debridement, ophthalmologic care, regular dressings, dietary modification, patient education, and home visits—the patient achieved glycemic control and complete ulcer healing. This case underscores the importance of prompt diagnosis, secondary prevention, and structured follow-up in the management of chronic diabetic complications.
