Diseases and Conditions

Bedsores (pressure ulcers)

Risk factors

Your risk of developing bedsores is higher if you have difficulty moving and can't change position easily while seated or in bed. Risk factors include:

  • Immobility. This might be due to poor health, spinal cord injury and other causes.
  • Incontinence. Skin becomes more vulnerable with extended exposure to urine and stool.
  • Lack of sensory perception. Spinal cord injuries, neurological disorders and other conditions can result in a loss of sensation. An inability to feel pain or discomfort can result in not being aware of warning signs and the need to change position.
  • Poor nutrition and hydration. People need enough fluids, calories, protein, vitamins and minerals in their daily diets to maintain healthy skin and prevent the breakdown of tissues.
  • Medical conditions affecting blood flow. Health problems that can affect blood flow, such as diabetes and vascular disease, can increase the risk of tissue damage such as bedsores.
