Pressure ulcers, also known as bed sores or pressure sores, are areas of damaged skin and tissue that develop when sustained pressure cuts off circulation to areas of the body, usually bony prominences like the hips, heels, and elbows. These wounds can be painful and lead to serious health complications if left untreated. Risk factors for pressure ulcers include immobility, poor nutrition, and medical conditions that affect blood flow. Treatment typically involves relieving pressure on the affected area, keeping the wound clean and moist, and addressing underlying health issues. Preventative measures such as repositioning, proper nutrition, and skin care are key in avoiding the development of pressure ulcers.
