Malnutrition is common in patients with chronic obstructive pulmonary disease (COPD), particularly as the disease progresses. This article looks at the nutritional issues facing patients with COPD, including the effects of medication, social and psychological issues. It outlines the role that general practice nurses (GPNs) can play by implementing the newly updated ‘Managing Malnutrition in COPD’ guidance. The guidance encourages incorporation of nutritional screening into COPD care pathways and the optimisation of nutritional intake for those at medium and high risk of malnutrition via dietary advice and oral nutritional supplementation, where appropriate. It also provides practical tips for patients with COPD to help manage common barriers to eating, such as shortness of breath, dry mouth and taste changes.
