Why is my wound not healing after surgery?

A surgical wound may heal slowly because of infection, separation, continued pressure or tension, poor blood flow, swelling, diabetes, smoking, nutrition problems, or medicines that affect healing. No single cause can be identified from appearance alone. Contact the surgical team if progress has stalled or the wound is opening, draining more, or becoming more painful.

Reasons healing can slow

Healing depends on blood supply, control of bacteria, protection from pressure and tension, and the person’s overall health. Diabetes, vascular disease, tobacco use, immune suppression, edema, inadequate nutrition, and repeated friction can interfere. A retained stitch or fluid collection may also require evaluation.

Changes to report promptly

Tell the surgical team about an enlarging gap, increasing drainage, a new odor, spreading redness, warmth, swelling, fever, or pain that worsens rather than improves. Bring the discharge instructions and a current medication list to the assessment.

How a clinician may reassess the wound

The clinician may evaluate wound depth, infection, blood flow, pressure, swelling, glucose control, nutrition, and the current dressing plan. Testing or treatment depends on the findings. Continue only the cleansing, dressing, activity, and medication plan provided by the treating team until reviewed.

Emergency red flags

Do not wait for a routine follow-up when the incision or the person worsens quickly.

  • The incision opens widely or internal tissue is visible
  • Heavy bleeding or rapidly spreading redness and swelling
  • Severe or disproportionate pain, blackening skin, or red streaks
  • Fever with confusion, fainting, breathing difficulty, or profound weakness
