Delayed wound healing

Wound healing varies between people. Sometimes a cut, surgical incision, or other wound closes more slowly than expected. Knowing common causes, when to seek professional assessment, and general measures that support healing can help you and your care team manage the process.

Common causes of slow healing

Multiple factors can slow wound repair. Typical contributors include infection, poor blood flow (circulatory problems), chronic conditions such as diabetes, nutritional deficiencies, older age, and obesity. Certain medications or conditions that weaken the immune system can also delay tissue repair. A clinician will review your history and examine the wound to identify which factors may be involved.

Smoking and healing after surgery (including otoplasty)

Smoking and tobacco use are linked to poorer wound outcomes. Nicotine and other substances reduce blood flow and limit oxygen and nutrient delivery to tissues, increasing the risk of complications after procedures such as otoplasty (prominent ear surgery). If you’ve had surgery, follow the instructions from your surgical team and discuss tobacco use with them to understand specific guidance for your recovery.

Practical measures that may support healing

General steps that can help wounds heal include a balanced diet with adequate protein and micronutrients, keeping the wound clean and following dressing instructions, avoiding habits that impair circulation (for example smoking), and managing chronic conditions like high blood sugar. Good follow-up with the treating clinician helps ensure any needed adjustments in care are made. These are general recommendations; individual care plans come from a healthcare professional.

When to get medical attention (warning signs)

Some symptoms need prompt evaluation rather than being labeled simply as ‘slow healing.’ Seek medical care if you notice fever, spreading redness around the wound, severe pain, foul-smelling or increased discharge, uncontrolled bleeding, rising swelling, or a rapidly enlarging wound. These signs can indicate infection or other complications and may require urgent assessment.
