Pressure ulcers, also known as bedsores or decubitus ulcers, are primarily caused by prolonged pressure on the skin. This occurs when there is sustained pressure on a specific area of the body, often leading to reduced blood flow and oxygen to the skin and underlying tissues. Over time, this can result in the skin breaking down, forming an ulcer.

Individuals who are unable to move independently, such as those who are bedridden or in wheelchairs, are particularly at risk because the same areas of skin may be subjected to pressure for extended periods. Maintaining regular repositioning of the patient and using proper support surfaces are essential strategies in preventing pressure ulcers, highlighting the importance of managing pressure effectively in vulnerable populations.

While other factors such as moisture, inadequate nutrition, and medication may contribute to the development and severity of pressure ulcers, the primary cause remains the sustained pressure applied to the skin.
