Answer :
Pressure ulcers are an injury that breaks down the skin and underlying tissue. They are caused when an area of skin is placed under pressure. They are sometimes known as "bedsores" or "pressure sores"
Pressure ulcers can develop when a substantial amount of pressure is applied to a skin area for a short time. They may also occur if less pressure is applied for an extended period of time. The increased pressure makes it impossible for blood to flow normally through the skin. Without blood flow, the injured skin loses nutrients and oxygen and begins to disintegrate, which leads to the formation of an ulcer Pressure ulcers can occur in people with medical conditions that make it difficult for them to move, especially if they are confined to lying in bed or sitting for long stretches of time. People with conditions like type 2 diabetes, which interferes with blood flow in the body, may also be more vulnerable .
