What is a major risk factor for developing pressure ulcers?

The inability to move or change position is a significant risk factor for developing pressure ulcers. When an individual cannot shift their weight or reposition themselves, areas of the body become susceptible to prolonged pressure against a surface, such as a bed or chair. This constant pressure restricts blood flow to the skin and underlying tissues, which can lead to tissue ischemia, cell death, and ultimately the formation of pressure ulcers.

In contrast, frequent ambulation can actually help prevent pressure ulcers by encouraging movement and reducing the amount of sustained pressure on any one area of the body. A high-protein diet and increased fluid intake support overall health and may contribute to skin integrity and healing. However, they do not directly address the mechanical risk factors associated with immobility, which is why the inability to move or change position is highlighted as a primary concern.
