Bedsores, more accurately called pressure sores or pressure ulcers, are areas of damaged skin and tissue that develop when sustained pressure cuts off circulation to vulnerable parts of your body, especially the skin on your buttocks, hips and heels. Without adequate blood flow, the affected tissue dies.
Although people living with paralysis are especially at risk, anyone who is bedridden, uses a wheelchair or is unable to change positions without help can develop bedsores.
Bedsores can develop quickly, progress rapidly and are often difficult to heal. Yet health experts say many of these wounds don't have to occur. Key preventive measures can maintain the skin's integrity and encourage healing of bedsores.
