Diabetic foot ulcer are the common complications of diabetes mellitus and it has significant mortality and morbidity in diabetic patients. Hemoglobin A1C (HbA1c) reflects glycemic control over 2–3 months and is the standard measure used to monitor glycemia in diabetic patients, the role of hemoglobin A1C (HbA1c) in assessing the outcome of diabetic ulcer needs to be evaluated. Aim: This study aims to determine the association of HBA1c level with healing of diabetic foot ulcer Materials and Methods: This study was conducted in the Department of Surgery, K V G medical college and hospital sullia over a period of 6 months from December 2018 to May 2019. A descriptive study was carried out in 80 diabetic patients with foot ulcers. The data collection included medical diagnoses, ulcer healing duration, and HbA1c results. Results: About 45 of patients with controlled HbA1c levels had their wounds healed in 2 to 3 months, whereas only 11 of patients with high HbA1c had their wounds healed in 2 to 3months. 24 of patients with high HbA1c had their wounds persisting for more than 6 months. Conclusion: HbA1c levels were associated with the process as well as the duration of foot ulcer healing in the diabetic patients. Elevated HbA1c was associated with poor prognosis in terms of foot ulcer healing.
