A chronic wound is a wound that shows no signs of significant healing in two weeks or has not healed in six weeks. The healing of a wound is dependent upon adequate oxygenation and blood flow to stimulate new cell growth and combat infection. Without effective treatment, a chronic wound may lead to more severe medical conditions.
A chronic wound is not a disease, but rather a symptom of a disease, deficiency, ailment or infection. There are a variety of conditions and situations that can impair, delay or otherwise affect the skins ability to heal.
Some leading causes of chronic wounds:
- Chronic diseases- Many chronic diseases, in particular diabetes, impact the wound healing process.
- Vascular Insufficiencies- Decreased blood supply to lower legs.
- Old age- Aged skin is more likely to deteriorate as the elasticity decreases with age.
- Obese or frail body type
- Long-term pressure applied to the body- Pressure ulcers or bedsores.
