Diabetic foot disease is a complex condition in which the long-term effects of diabetes can lead to foot wounds, infection and tissue loss.
A small callus, shoe-related irritation or cut may progress unnoticed because of loss of sensation, inadequate circulation and susceptibility to infection.
- Loss of sensation may conceal a wound
- Poor circulation may delay healing
- Infection may spread to deeper tissues
- Early assessment matters
Nerve damage (diabetic neuropathy)
Numbness, tingling, burning or loss of sensation may occur. Reduced pain sensation may delay recognition of cuts and pressure wounds.
Poor circulation
Reduced blood flow to the foot can affect tissue oxygenation, delay wound healing and reduce resistance to infection.
Susceptibility to infection
An impaired immune response in diabetes may allow a small wound to become infected quickly and spread into deeper tissues.
Why is assessment multifaceted?
Diabetic foot does not result from a single problem. Sensation, circulation, infection, pressure and foot structure should be assessed together.
The absence of pain does not mean it is safe
People with diabetes should check their feet every day and contact their healthcare team for a new wound, color change, discharge or swelling.
