Any burn that is deep or widespread can lead to complications, including:
Bacterial infection, which may lead to bloodstream infection (sepsis)
Damaged blood vessels can cause a victim to lose fluids, affecting heart function
Dangerously low body temperature (hypothermia): The skin controls the body’s temperature, so when a burn damages the skin, the body may lose too much heat
Respiratory problems due to the intake of hot air or smoke
Permanent scars and disfigurement, caused by an overgrowth of scar tissue (keloids)
Bone and joint problems: In some cases, scar tissue can shorten or tighten the skin, muscles, or tendons, causing the injured person to have limited mobility
