Changes in nutritional status, such as weight loss and malnutrition, are a very common complication in patients with chronic obstructive pulmonary disease (COPD). These changes primarily affect the patients' quality of life and functional capacity and they are also independent prognostic indicators of both morbidity and mortality. Malnutrition in these patients is due to multiple factors including increases in resting energy expenditure, decreased food intake, the effects of certain drugs, and, perhaps most importantly, a high systemic inflammatory response.

The present review covers the most important facets of the prevalence, etiology, pathogenesis, and consequences of malnutrition in COPD and considers which parameters for nutritional assessment are the most satisfactory for use in routine clinical practice. The strategy used to ensure correct nutritional status in these patients is also discussed.

Nutritional assessment

Las alteraciones nutricionales, entendidas como pérdida de peso o desnutrición, son una complicación muy frecuente en los pacientes con enfermedad pulmonar obstructiva cró-nica (EPOC) y afectan principalmente a su capacidad fun-cional y calidad de vida, además de constituir un indicador pronóstico de morbilidad y mortalidad independientes. Los factores que contribuyen a la desnutrición son múltiples; en-tre ellos cabe mencionar el aumento del gasto energético en reposo, el descenso de la ingesta, el efecto de determinados fármacos y, quizá el más importante, una elevada respuesta inflamatoria sistémica.

En este artículo se pretende revisar los aspectos más im-portantes sobre la prevalencia, etiopatogenia y efectos de la desnutrición en la EPOC, además de discutir los parámetros de valoración nutricional más adecuados en la práctica clí-nica diaria y la estrategia para que estos pacientes manten-gan un correcto estado nutricional.
