Why do bedsores (pressure ulcers) develop? There are four main causes: pressure, shearing, friction, and moisture.

Bedsores are called "pressure ulcers" in medical and nursing care settings. They are a condition in which the skin and underlying tissues are damaged due to prolonged pressure on the same area. In many cases, early detection and intervention can prevent them from worsening.

4 causes

• Compression: Weight is concentrated on the bony areas, impairing blood flow.
• Shifting: When the backrest is raised, the skin is pulled.
• Friction: Skin rubs against each other during diaper changes or when moving.
• Dampness: Sweat and incontinence cause the skin to become soft and more susceptible to injury from even slight irritation.

Areas prone to bedsores

These tend to form on the buttocks (sacrum), heels, and the outer sides of the hips and thighs when sleeping on your side. Wheelchair users should also pay attention to their ischial tuberosities (sit bones).

Things that only family members can notice

If you notice changes such as "the same spot is always red" or "the redness doesn't go away easily," you should consult a medical or care professional as soon as possible.
