Introduction

Diabetic foot is a debilitating complication that affects individuals with diabetes mellitus, posing significant challenges in terms of morbidity, mortality, and healthcare costs. It encompasses a range of foot disorders, including peripheral neuropathy, peripheral vascular disease, foot ulcers, and infections. Diabetic foot requires a comprehensive understanding of its pathophysiology, accurate assessment methods, and a multidisciplinary approach to its management [1]. This article provides a comprehensive review of the pathophysiology, assessment, and multidisciplinary management of diabetic foot. The pathophysiology of diabetic foot is multifactorial and involves the interplay of several mechanisms. Prolonged hyperglycemia leads to peripheral neuropathy, characterized by sensory, motor, and autonomic dysfunction, which predisposes individuals to foot ulcers and injuries [2, 3]. Additionally, diabetes-related vascular changes, such as macro- and microangiopathy, contribute to compromised blood flow, impaired wound healing, and increased susceptibility to infection. Understanding these underlying mechanisms is crucial for developing targeted interventions to prevent and manage diabetic foot complications. Accurate assessment of diabetic foot is essential for appropriate management. Clinical examination plays a vital role in evaluating neuropathy, assessing peripheral pulses, examining skin integrity, and identifying deformities or ulcerations. Various diagnostic tests, including monofilament testing, Doppler ultrasound, and imaging techniques, provide valuable insights into the severity of neuropathy, vascular status, and the presence of complications such as osteomyelitis [4-6]. Multidisciplinary management is a cornerstone in the comprehensive care of individuals with diabetic foot. A collaborative approach involving endocrinologists, podiatrists, wound care specialists, vascular surgeons, orthopedic surgeons, and infectious disease specialists ensures comprehensive evaluation and tailored treatment plans [7].

The management of diabetic foot encompasses various components

Glycemic control is crucial in reducing the risk of complications and promoting wound healing. It involves lifestyle modifications, pharmacological interventions, and insulin therapy aimed at achieving optimal blood glucose levels. Neuropathy management includes regular foot examinations, education on foot care, and the use of appropriate footwear to prevent neuropathic ulcers and injuries. Symptomatic relief may be achieved through medications such as alpha-lipoic acid and certain antiepileptic drugs [8-10]. Vascular assessment and intervention play a critical role in improving blood flow to the foot and promoting wound healing. Revascularization procedures and endovascular interventions may be necessary to restore arterial perfusion and prevent amputation. Wound care and infection management are essential in diabetic foot management [11-13]. Comprehensive wound assessment, debridement, offloading techniques, advanced dressings, and appropriate antibiotic therapy help facilitate wound healing and prevent the spread of infection. Surgical interventions, including corrective procedures such as bony realignment, tendon transfers, and Charcot foot reconstruction, may be required to restore foot function, correct deformities, and prevent further ulcers or complications. Education and patient self-management are integral components of diabetic foot management. Educating patients about proper foot care, early detection of problems, and adherence to treatment regimens empowers them to actively participate in their care, promoting self-care and reducing the risk of complications [14].

This comprehensive review aims to provide healthcare professionals with a comprehensive understanding of the pathophysiology, assessment, and multidisciplinary management of diabetic foot. By adopting a proactive approach, early intervention, and a multidisciplinary team-based approach, it is possible to minimize the risk of complications, optimize wound healing, and improve the overall quality of life for individuals with diabetic foot [15]. Continued research and collaboration are necessary to refine treatment approaches, develop innovative strategies, and improve outcomes for individuals affected by this challenging condition.
