The wound healing process is a complex and orderly process
It can be roughly divided into the following stages:
Stages of hemostasis and inflammatory response:
When an injury occurs, blood flows out of the wound, triggering an inflammatory response. This stage is mainly to stop bleeding and remove bacteria and necrotic tissue from the wound.
Stages of cell proliferation and granulation tissue formation:
After the inflammatory response, new cells begin to proliferate, forming granulation tissue. Granulation tissue is composed of neovascular, fibrous connective tissue, and various inflammatory cells that provide essential nutrients and structural support for wound healing.
Organizational Remodeling Phase:
As granulation tissue forms, new tissue begins to grow and replace the damaged tissue. This stage requires a large amount of protein synthesis and cell differentiation to eventually form structures similar to the surrounding tissues.
Scarring Stages:
During wound healing, fibrous connective tissue gradually replaces normal tissue structures, forming scars. The formation of scar tissue is a natural phenomenon in the wound healing process, and although it is different from normal tissue, it usually does not affect function.
It should be noted that
The wound healing process is influenced by a variety of factors
If it doesn't heal for a long time, it may be caused by these reasons:
Infection
Wound infection is one of the main causes of long-term wound healing. Microorganisms such as bacteria and viruses multiply within the wound, destroying tissues and hindering the healing process.
Malnutrition
Deficiencies in nutrients such as proteins, vitamins, etc., can affect the speed and quality of wound healing.
Abnormal blood sugar levels
Blood sugar levels that are too high or too low in people with diabetes can affect wound healing.
Poor blood circulation
Poor circulation affects oxygen and nutrients** around the wound, which affects the speed of healing.
Psychological stress
Long-term psychological stress and anxiety can affect immune system function, which can affect wound healing.
How to promote wound healing
Clean the wound
Keeping the wound clean is key to preventing infection. Wash the wound regularly and avoid using harsh cleansers.
Supplemental nutrition
Ensure adequate intake of nutrients such as protein and vitamins to help wound healing.
Control your blood sugar
People with diabetes should actively control their blood sugar levels and avoid getting too high or too low.
Improves blood circulation
Improve blood circulation and promote wound healing through proper exercise and massage.
Reduce psychological stress
Maintain a good state of mind and mood, reduce psychological stress, and help wound healing.
Precautions
Avoid self-treating wounds
Do not squeeze, scratch, or apply unknown drugs to avoid aggravating the wound infection.
Seek prompt medical attention
If the wound is red, swollen, painful, pus-draining, etc., you should seek medical attention promptly**.
Follow your doctor's instructions
Follow your doctor's advice for ** and care and do not change ** regimen on your own.
