What causes slow wound healing?

Getting injured is common in life, but it is important to treat the wound in a timely manner after the injury. Some people's wounds heal very slowly. As for the reason for slow wound healing, this is most likely due to wound infection, which is also the most common cause affecting wound healing.

1. Wound infection

Wound infection is the most common cause affecting wound healing. In addition to the common infections caused by Staphylococcus aureus, Streptococcus, and Escherichia coli, there is also the possibility of infection by Pseudomonas aeruginosa, Mycobacterium tuberculosis, and fungi.

2. There is foreign matter in the wound

When the body is injured by sharp nails, splinters, glass and other objects, it is very likely that small foreign objects will be left in the wound during debridement. Such wounds with foreign objects are difficult to heal. Despite repeated dressing changes, the redness, swelling and pain of the wound do not improve, and the secretions do not decrease. If the foreign objects in the wound can be removed in time and then treated with antibiotics, the wound can heal quickly.

3. Granuloma edema

Repeated dressing changes, especially irregular dressing changes, can easily lead to wound granulation edema. The edematous granulation tissue is pale white or light red, has a lot of secretions, and is higher than the skin, which delays the healing of the wound.

4. General malnutrition

Most people with chronic wasting diseases such as tumors, diabetes, tuberculosis, etc. have poor overall nutrition and weak collective resistance, which affects wound healing. Especially for cancer patients who have undergone chemotherapy and radiotherapy, wound healing is more difficult.

5. Scar-prone constitution

The patient's own physique is likely to be a scar-prone physique. Coupled with the large wound or the lack of timely supply of nutrients in the patient's body during the wound healing period, this directly leads to the slow synthesis of new cells, making the patient's wound healing extremely slow.

6. Others

Factors such as hematoma in the wound, poor drainage, and poor skin suture at the suture site are also reasons that make it difficult for the wound to heal.
