Causes of non-healing leg wounds

Non-healing wounds are quite common in our daily life. There are many reasons for this, which are related to personal constitution and normal nutritional status. If the physical constitution is poor, the wounds may not heal easily. It is also related to age. The older you are, the slower the metabolism of your skin, which will also affect the speed of wound healing. We should have some understanding in this regard and adopt certain treatment methods to accelerate the healing of wounds.

What causes slow wound healing?

Reasons for slow wound healing: 1. Nutritional status

It is also the main factor affecting wound healing. Nutritional status The quality of nutritional status will directly or indirectly affect wound healing. For example, protein deficiency can slow down the formation of new blood vessels, fibroblast proliferation and collagen synthesis; at the same time, it can affect the phagocytic function of cells, reduce immunity, slow down tissue repair, and make wounds difficult to heal. Especially when sulfur-containing amino acids are deficient, it often leads to poor or slow tissue cell regeneration and obstructed granulation tissue formation. At the same time, if the patient's diet lacks trace elements such as vitamin C, zinc, and iron, it will also affect the healing speed of the wound.

Reason 2 for slow wound healing: Age factor

It will affect the healing speed of wounds. The regenerative capacity of tissue cells at different ages is different, and generally the tissue regeneration capacity decreases with age. In addition, the elderly are prone to hardening of blood vessels, which reduces local blood supply, and the division and proliferation cycle of fibroblasts is significantly prolonged, and cell activity is generally reduced, resulting in delayed wound healing, decreased healing quality, and even non-healing.

Reason 3 for slow wound healing: Improper medication

It will cause slow wound healing. Many patients indiscriminately use antibiotics to treat wounds, which may also cause symptoms of slow wound healing. Another serious problem with topical application of antibiotics is that they can cause contact allergic reactions, especially when they are used extensively and for a long time on chronic wounds. The use of some antibiotics can impair wound cell proliferation and epithelial formation, kill macrophages that are beneficial to healing, and thus affect wound healing. In comparison, choosing a wound-healing drug such as a wound-healing prescription for treatment will greatly increase the speed of wound healing, so the treatment

Reasons for slow wound healing 4. Certain systemic diseases

It will affect the speed of wound healing. If the patient has systemic diseases such as diabetes, anemia, rheumatoid arthritis, autoimmune diseases, malignant tumors, liver failure, and renal insufficiency, the wound will also heal slowly.

Reason 5: Obesity

Will slow down wound healing. Extensive subcutaneous fat in obese patients can easily form dead space and hematoma after surgery, which hinders the release of blood oxygen to the wound and provides a focus for infection; the blood supply of adipose tissue is relatively small, and the wound is insufficiently supplied with blood, which is prone to liquefaction necrosis; too much adipose tissue will increase the tension of the wound (primary suture of the wound), which will hinder the local blood circulation of the wound and affect wound healing.

Reason 6: Patient's psychological state

It may also cause wounds to heal more slowly. Patients are in a negative psychological state of depression, tension, and anxiety for a long time, which indirectly affects wound healing by damaging the body's immune function through the neuroendocrine system. On the contrary, a positive attitude will help wounds heal.
