Introduction
Skin wounds that fail to heal are commonly associated with the following conditions:
- Inadequate wound care after injury may lead to bacterial infection, which not only impairs wound healing but may also result in wound suppuration and systemic infection.
- Insufficient dietary nutrition can similarly hinder wound healing—particularly in patients with severe trauma, whose wounds require substantial amounts of nutrients and trace elements for proper recovery.
In daily life, everyone is prone to bumps and bruises that result in skin wounds. However, some individuals notice that their skin wounds consistently fail to heal. The specific reasons are as follows:
① Age
As people age, the body’s tissue regeneration capacity declines. Additionally, older individuals often experience varying degrees of vascular hardening, leading to reduced local blood supply. Moreover, the division and proliferation cycle of skin fibroblasts lengthens, thereby prolonging the wound-healing process—or even preventing healing altogether.
② Infection
If proper wound care is neglected after injury, bacterial infection may occur. Such infection not only delays wound healing but may also lead to abscess formation and systemic infection. Therefore, meticulous wound care following injury is essential to prevent infection.
③ Nutrition
Inadequate dietary intake similarly impairs wound healing—particularly in patients with severe trauma, whose wounds require substantial nutrients and trace elements for recovery. Key substances promoting wound healing include protein, glucose, vitamin C, and zinc. Selective or restricted eating habits post-injury may result in insufficient intake of these essential nutrients, thereby hindering wound healing.
