Diabetes Mellitus (DM) affects your body’s ability to process sugar. Consistently high blood sugar levels can lead to various complications, notably foot ulcers. If you have diabetes, your risk for foot ulcers increases due to several factors, including neuropathy (nerve damage) and peripheral vascular disease, both of which can impair foot health.

Neuropathy diminishes your ability to feel pain, often resulting in unnoticed injuries to the feet. Combined with poor circulation from peripheral vascular disease, the healing process for these wounds can be slow, elevating the risk of infection and subsequent complications such as amputation. Considering proper foot care is fundamental for you if you are managing diabetes.

Foot ulcers are characterized by sores that do not heal or repeatedly return. They can develop under your foot, often over areas of stress and pressure from walking or standing. To manage and prevent foot ulcers, religiously monitor your blood sugar levels, inspect your feet daily, and maintain good hygiene and proper footwear.

Be aware of the classification of diabetic ulcers, as this can influence treatment strategies. Effective management of foot ulcers could involve various approaches, including but not limited to, debridement of wounds, infection control, and pressure offloading. Always consult healthcare professionals experienced in diabetic foot management for personalized and appropriate care.

Understanding the pathophysiology of diabetic foot ulcers (DFUs) is critical for managing your diabetes and preventing serious complications. This section will explore how uncontrolled blood glucose, neural and vascular damage, and infection contribute to the development of these ulcers.

Blood Glucose Control and Complications

Your ability to regulate blood glucose levels plays a pivotal role in the health of your feet. Persistently high levels of sugar in your blood can lead to the formation of Advanced Glycation End-products (AGEs), which further damage the structural proteins in your skin and blood vessels. These changes impair wound healing, making you more susceptible to skin breakdown and ulcer formation.

Neuropathy and Vasculopathy

Chronic high blood sugar can cause significant nerve damage, termed diabetic neuropathy, reducing sensation in your feet. This can prevent you from feeling injuries, leading to unnoticed and untreated wounds. In conjunction with peripheral arterial disease (PAD), which restricts blood flow to your feet, the risk of developing ulcers increases as the skin and tissues receive less oxygen and nutrients necessary for repair.

Infection and Ulceration

When a foot ulcer develops, the risk of infection is high due to the presence of various bacteria. A compromised immune response, commonly seen in diabetes, along with reduced blood flow from vasculopathy, creates an environment where bacteria can flourish, leading to further complications of the DFUs. It is crucial to recognize signs of infection promptly, such as redness, swelling, and discharge, to seek appropriate treatment.

Risk Factors
