Early recognition of diabetic foot ulcer infection is crucial to prevent progression to a limb-threatening or even life-threatening condition. The challenge is that diabetic patients may not feel pain due to neuropathy, so visual signs must be relied upon.
Local Infection Signs (Mild):
- Redness around the ulcer: More than 0.5 cm around the ulcer edge.
- Swelling: Puffiness in the surrounding area.
- Local warmth: The area is warmer than surrounding skin.
- Purulent discharge: Yellow or green pus or foul odor.
Serious Infection Signs (Require Emergency Visit):
- Extensive redness: More than 2 cm around the ulcer or ascending red streaks (lymphangitis).
- Fever or chills: Body temperature above 38°C.
- Foot color change: Purple or black color — sign of possible gangrene.
- Very foul odor: May indicate serious anaerobic infection.
- Sudden blood sugar spike: Unexplained high blood sugar may be the first sign of infection.
