What Are The Stages of Wound Healing

Wounds heal in stages. It doesn’t happen overnight, as you might have noticed. Depending on the severity of the injury, healing might take from 3 weeks to 2 years. The process can be categorised into different parts.

The 4 commonly-known phases are:-

  1. Inflammation
  2. Epitheliazation
  3. Angiogenesis
  4. Remodeling

Inflammation

This goes hand in hand with blood clotting. The bleeding tissues will need to have the blood that is oozing out controlled and stopped. Platelets from the blood stick to the injury, releasing chemicals that call for blood clotting whose main purpose is to block the break in blood vessels. This happens as inflammation proceeds: white blood cells that have accumulated in the affected tissues will get rid of damaged and dead cells, thereby removing any debris left.

Inflammation might last for 2 to 5 days.

Epitheliazation

This occurs during scab formation which is promoted by blood clotting. New skin will grow beneath the scab, and constriction of the outer edges of the wound begins. The new skin will ultimately hold the edges together,

It lasts for a few days or weeks.

Angiogenesis

As the new skin grows and holds the wound together, new blood vessels start to form under it as a substitute to the broken vessels.

Remodeling

This is marked by the flaking off of the scab which is followed by the formation of collagen. The wound’s remnant, the scar, will start appearing. The new tissue will not, however, be as strong as the preceding one. At the complete formation of the scar, the wound will have been completely healed.
