CAUSES OF WEIGHT LOSS


Potential causes of weight loss are strongly influenced by the age at presentation. For example, in young adults, unintentional weight loss is often due to psychiatric disorders such as depression, anorexia nervosa, bulimia, psychoses and substance abuse. In contrast, weight loss in the elderly is often due to multiple factors including social isolation, bereavement, dementia, depression, poor dentition and side effects from drugs. In middle age, there may be a greater contribution from cancer, alcoholism, endocrine disorders and chronic inflammatory disorders. Cancer is diagnosed in up to 25% of patients with weight loss over the age of 50 years. Some of the factors that contribute to weight loss are outlined below and are summarised in Figure 24.1.
