For patients with Alpha-1 Antitrypsin Deficiency (AATD), who often develop Chronic Obstructive Pulmonary Disease (COPD), lifestyle modifications are crucial for improving health outcomes ,. You should advise patients on the following:

  • Smoking Cessation and Avoidance of Passive Smoke: It is vital to offer treatment and support to help patients stop smoking, and advise them to avoid exposure to passive smoke ,. Continued smoking or exposure to passive smoke increases the risk of exacerbations .
  • Physical Activity and Pulmonary Rehabilitation: Encourage regular physical activity ,. Offer pulmonary rehabilitation to appropriate patients who are functionally disabled by their condition ,. This multidisciplinary programme includes physical training, disease education, and nutritional, psychological, and behavioural interventions . Lack of physical activity is a risk factor for exacerbations .
  • Nutritional Advice: Calculate the patient's Body Mass Index (BMI) . If their BMI is abnormal (high or low) or changing over time (e.g., more than 3 kg change in older people), refer them for dietetic advice ,. For those with a low BMI, nutritional supplements may be given to increase calorific intake, alongside encouragement to exercise . Nutrition should also be part of pulmonary rehabilitation programmes ,.
  • Vaccinations: Offer pneumococcal vaccination and an annual flu vaccination to all patients ,.
  • Self-Management Strategies: Develop an individualised self-management plan in collaboration with the patient and their family or carers ,. This plan should include information on COPD symptoms, managing breathlessness, appropriate use of inhaled therapies, and early recognition and management of exacerbations ,.
  • Addressing Psychological Well-being: Be alert for anxiety and depression, particularly in patients with severe breathlessness or those who have had recent hospital admissions for exacerbations . Consider referral to psychological services if anxiety or depression related to COPD is identified ,.
  • Sputum Clearance Techniques: If patients have excessive sputum, they should be taught how to use positive expiratory pressure devices and active cycle of breathing techniques, often by a physiotherapist ,.
