Abstract :

Nutritional abnormalities are oft en associated with Chronic Obstructive Pulmonary Disease (COPD). Th eir early detection is important, since they determine the patient's prognosis independently of the degree of lung function impairment. In addition, nutritional abnormalities are involved in muscle dysfunction, which in turn leads to exercise limitation, loss of quality of life and increased mortality. However, the presence/absence of malnutrition is a factor that has not been included in the majority of clinical guidelines. Th e diagnostic techniques include both anthropometry and measurement of body composition (mainly through bioelectrical impedance). Th e most commonly used anthropometric variables are body mass index (BMI) and the percentage of ideal body weight, while fat-free mass index (FFMI) is the most commonly used impedance variable. Th e causes of malnutrition associated with COPD include smoking, systemic infl ammation, imbalance between nutrient intakes and energy consumption, impairment in respiratory gas exchange and the eff ects of anabolic hormones, eff ects of some drugs, decreased physical activity and comorbidities. All these causes lead mainly to an imbalance between protein synthesis and destruction and a predominance of bone resorption with loss of muscle, fat and bone mass. Th e treatment includes an improvement in lifestyle (avoid tobacco smoking, better quality in nutrient intake, increase in physical activity, exercise training) and if necessary, the use of nutritional support (enteral or even parenteral) and anabolic agents (e.g., selective androgen receptor modulators [SARM] or secretagogues of the growth hormone). Th ese drugs seem to be more eff ective when associated with training.
