What initiates inflammation in the healing process?

Inflammation is a critical part of the body's healing process, and it is primarily initiated by an injury. When tissues are damaged, whether from physical trauma, a cut, or a sprain, the body responds by activating the inflammatory response. This involves the release of various biochemical mediators, such as histamines and prostaglandins, which lead to increased blood flow and the accumulation of immune cells at the site of injury. These cells work to remove damaged tissues, prevent infection, and begin the repair process.

Injuries trigger a series of physiological changes intended to protect the affected area and encourage healing. While illnesses, chronic conditions, and stress can influence inflammation, they do not directly initiate the inflammatory response in the same way that an injury does. Inflammation from an injury serves as a protective mechanism, allowing the healing process to begin promptly.
