Understanding Wound Healing Failure: Causes & Prevention

Wound healing failure occurs when a wound stalls or deteriorates. Common causes:

• Infection: Bacterial/fungal/viral—most common cause; delays granulation.
• Inadequate Perfusion: Poor arterial/venous supply limits oxygen/nutrient delivery.
• Foreign Bodies: Debris, suture material, glass—nidus for infection, tissue damage.
• Diabetes: Microvascular disease, neuropathy, immune dysfunction impair healing.
• Obesity: Adipose tissue hypoxia, chronic inflammation, technical challenges.
• Smoking: Vasoconstriction, reduced oxygen, impaired angiogenesis.
• Alcohol Abuse: Liver dysfunction → reduced protein synthesis; immune suppression.
• Corticosteroids: Suppress inflammation, fibroblast proliferation, collagen synthesis.
• Malnutrition: Protein, vitamin (C, A, Zn) deficits.
• Medications: Chemo, immunosuppressants, anticoagulants.

Action

Seek immediate medical evaluation. Treatment targets underlying cause: debridement, antibiotics, revascularization, glycemic control, nutrition optimization, smoking cessation, medication review.
