There are myriad ways in which people can experience physical wounds—from minor scrapes and abrasions to the effects of surgery, critical injuries, burns and other major traumas. The healing process for these wounds can also vary among individuals and may be adversely affected by underlying health conditions such as vascular insufficiencies, diabetes, obesity and advanced age. In severe cases, abnormal wound healing processes can result in chronic wounds, a condition which can dramatically affect mobility, quality of life and healthcare costs.
