Weight loss can be either intentional (eg. By increased exercise and dieting) or unintentional. Unintentional weight loss may be due to a Medical problem and can lead to malnutrition with decreased body muscle mass and loss of essential vitamins and proteins. There are many possible causes for weight loss including malabsorption conditions such as coeliac disease and gut inflammation. An important cause in people with advancing age is cancer and urgent investigation is advised if suspected.
Treatment is closely co-ordinated with dieticians and directed towards the underlying cause with diet and nutrition plans being the main focus of improving the malnutrition state. Food and supplements may be required to improve symptoms and the person’s condition.
