Causes of Non-Healing Wounds

Non-healing wounds can be extremely frustrating, and potentially even dangerous. While most wounds heal in about three weeks or so, some can take months or even years. Here are some of the reasons why.

Infections

The most common factor that causes non-healing wounds is infection. If a wound becomes infected or contaminated, the body’s immune system directs its efforts toward fighting bacteria rather than healing. Bacteria can also cause cell death as well as toxins that can delay or stop healing. A bite is an example of a wound that can easily be contaminated.

Poor Circulation

The blood is vitally important in delivering nutrients and oxygen to a wound, as well as removing debris, bacteria and toxins. For a variety of reasons, many people have poor blood circulation and, as a result, have non-healing wounds. Diabetes, high blood pressure, peripheral vascular disease and other issues can cause insufficient circulation.

Wound Condition

If the area of the wound suffers repeated trauma or an excessive amount of pressure is applied to the area, then healing can be delayed. Dehydration can lead to the wound drying up and crusting over, but over-hydration can be just as troublesome. It can cause the wound to moisten and erode.

Medications

There are certain drugs, such as corticosteroids, that can inhibit the body’s inflammatory response. In addition, patients undergoing chemotherapy often have issues with non-healing wounds because cells do not proliferate. Those going through radiation therapy often have an increased risk of infection.

Age

Older adults often do not heal as quickly as children and healthy adults because their skin tends to be more fragile and susceptible to infections. Their bodies also typically do not have the ability to produce needed antibodies. Many elderly people also have chronic diseases such as heart disease and diabetes, which lead to poor circulation as well as impair the oxygenation needed to promote healing.
