What Causes Bed Sores (Pressure Ulcers)?
Bed sores, also called pressure sores or pressure ulcers, happen when the weight of the body presses the blood out of an area long enough to deprive the tissues of their blood supply, damaging the skin and tissue. When the tissue dies, bed sore treatment may require the affected area to be surgically removed, which may involve amputation. Bed sores can happen when a patient is in one position too long, whether in bed or sitting in a chair or wheel chair.
