Introduction
Non-healing skin wounds are commonly associated with the following conditions:
**Infection**: Failure to properly care for a wound after injury may lead to bacterial infection, which not only impairs wound healing but may also result in suppuration and systemic infection.
**Nutrition**: Inadequate dietary intake 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 becomes prolonged, thereby extending the wound-healing process—or even preventing healing altogether.
② Infection
Failure to properly care for a wound after injury may lead to bacterial infection, which not only impairs wound healing but may also cause suppuration and systemic infection. Therefore, diligent wound care is essential following injury to prevent infection.
③ Nutrition
Inadequate dietary nutrition can likewise hinder wound healing—particularly in patients with severe trauma, whose wounds require substantial nutrients and trace elements. Key substances promoting wound healing include protein, glucose, vitamin C, and zinc. Selective or restrictive eating habits after injury may result in insufficient intake of these essential nutrients, thereby impairing wound healing.
