[Dietary supplements are useful in the prevention and treatment of pressure sores].

The causal relationship between nutrition and pressure sores (PS) remains unclear. Nevertheless, it is evident that many acute and chronically ill patients, at risk of PS or with established PS, have undesirable weight loss and malnutrition. Providing extra nutritional supplements in addition to regular food intake seems a logical way to replenish body shortages of macro- and micronutrients as well as to supply extra nutrients for the preservation of skin tissue, strengthening oftissue resistance, and promoting tissue repair. This is relevant because malnourished patients, at risk of PS or with established PS, often have problems in fulfilling their nutritional needs by normal food intake.
