Pressure ulcers (also called bed sores) are sores on the skin caused by pressure or rubbing at the weight-bearing, bony points of immobilised people (such as hips, heels and elbows). Poor nutritional status or dehydration can weaken the skin and make people more vulnerable to developing pressure ulcers. Nutritional interventions to try and prevent or treat pressure ulcers include providing additional nutrition and dietary supplements, including zinc and vitamin C. The review of trials found that although there is some evidence that nutritional interventions may be able to reduce the number of people who develop pressure ulcers, more evidence is needed to identify effective dietary interventions.
