Pressure ulcers, also known as bedsores or pressure sores, are a common problem faced by many people who are bedridden or have limited mobility. These sores occur when there is continuous pressure on a particular area of the skin, leading to damage and skin breakdown. There are various synonyms for this condition, including decubitus ulcers, pressure sores, skin breakdown, ulceration, and pressure injuries. However, the most commonly used term is pressure ulcer. It's important to keep the affected area clean and dry to prevent infection. Pressure ulcers can be prevented by regularly changing the position of the bedridden person and using specialized cushions and mattresses designed to reduce pressure on specific areas.
