Signs of malnutrition are not always weight loss, they can be physical, such as dry skin and hair, brittle nails, or sores around the mouth. They can also be psychological, including increased irritability and depression.
It is estimated that over 3 million people in the UK are malnourished or at risk of malnutrition. Our elderly population is particularly at risk: over 1 million of those affected are over 65. Malnutrition does not just look skinny.
