Word: Decubitus Ulcer

Definition: A decubitus ulcer, also known as a pressure sore or bedsore, is a sore that develops on the skin when someone stays in one position for too long, especially if they are bedridden or unable to move easily. The pressure on the skin can cut off blood flow, leading to skin damage and open wounds.
