This article explores the natural ageing process and the impact it can have on the nutritional status of elderly patients. In the article, the author considers the body’s ageing process and the changes patients can struggle with as a result. Recognition, identification and treatment of malnutrition with this patient group is an essential part of care within the NHS, which, if done appropriately, can improve patient quality of life - in particular, functional status.
