A bedsore, also known as a pressure ulcer or pressure sore, is an injury to the skin and underlying tissue caused by prolonged pressure on the skin. Bedsores commonly occur in areas where bones are close to the skin, such as the tailbone, hips, heels, and elbows. They can range from mild redness to open wounds that expose deeper tissues. Bedsores are particularly common in people who are bedridden or have limited mobility, as they may have difficulty shifting their weight or changing positions regularly. Prevention involves regularly changing positions, using cushions or special mattresses to relieve pressure, keeping the skin clean and dry, and maintaining good nutrition. Treatment may include cleaning and bandaging the wound, relieving pressure, and addressing any underlying medical conditions.
