Understanding poor wound healing

Normal wound healing occurs in stages: inflammation, tissue formation, and remodelling. When any of these stages are disrupted, wounds may remain open for prolonged periods or heal abnormally. Poor wound healing is not a disease itself but a sign of an underlying issue, making it important to identify and address the cause.

Causes of poor wound healing

Diabetes: High blood sugar damages blood vessels and impairs immune function.
Poor circulation: Peripheral arterial disease or venous insufficiency reduces oxygen supply to tissues.
Infection: Bacterial contamination delays healing and increases inflammation.
Immune system disorders: Conditions such as HIV or medications like steroids suppress normal repair processes.
Nutrition deficiencies: Lack of protein, vitamin C, zinc, or iron can slow tissue repair.
Lifestyle factors: Smoking, alcohol, and obesity negatively impact healing.

Symptoms and warning signs

Indicators of poor wound healing include:

Wounds that remain open for weeks
Slow or incomplete closure of surgical wounds
Persistent redness, swelling, or pain
Foul-smelling discharge or pus
Blackened or dead tissue around the wound edges

Diagnosis

A dermatologist or specialist will examine the wound and may perform tests such as:

Wound swabs to check for infection
Blood tests for diabetes, anaemia, or nutritional deficiencies
Doppler ultrasound to assess circulation
Biopsy in rare cases to rule out skin cancer or chronic ulcer complications

Treatment and management

Wound care: Special dressings, debridement, and infection control.
Medications: Antibiotics for infection, optimising diabetes or vascular treatment.
Nutrition support: High-protein diet and supplementation if needed.
Lifestyle advice: Stopping smoking, maintaining a healthy weight, and good hygiene.
Advanced therapies: Negative pressure wound therapy, growth factor treatments, or skin grafting in severe cases.

Living with slow-healing wounds

Poor wound healing can affect quality of life, leading to discomfort, reduced mobility, and psychological stress. Regular follow-up with a dermatologist or wound care specialist ensures complications are minimised and healing is supported.

Your first visit — what to expect
