A non-healing diabetic foot ulcer is at risk for which serious complication if not properly managed?

• A. Amputation
• B. Spontaneous healing without infection
• C. No increase in infection risk
• D. Worsening anemia but not infection risk

Answer: (A)

Chronic non-healing diabetic foot ulcers signal that infection and tissue damage can escalate to involvement of deeper structures, including bone, and even systemic infection. In diabetes, impaired immune response and poor blood flow slow healing and allow bacteria to spread more easily. When infection and necrosis progress, the limb may become non-viable, and amputation can become necessary to remove the source of infection and prevent life-threatening sepsis. So, the most serious possible complication if such a wound isn’t properly managed is amputation.

Spontaneous healing without infection is unlikely in a non-healing diabetic ulcer, and while infection risk is real, it’s the progression to severe damage and potential amputation that represents the critical danger. Worsening anemia is not the primary concern driving the urgency in this context.
