In the UK approximately 1.2 million people have COPD with around 25–40% being underweight and 35% have a severely low fat-free mass index. Measuring their body mass index is recommended and Health care professionals should endeavour to ensure that COPD patients are achieving their nutritional requirements.

A narrative review summarizes evidence from 28 original articles identified through a systematic searches of databases, grey literature and hand searches covering 15 years, focusing on two themes, on the impact of malnutrition on COPD, and the management of malnutrition in COPD.

Malnutrition causes negative effects on exercise and muscle function and lung function as well as increasing exacerbations, mortality and cost. Management options include nutritional supplementation which may increase weight and muscle function. Nutritional education has short-term improvements.

Malnutrition affects multiple aspects of COPD, but treatment is of benefit. Clinical practice should include nutrition management.

在英国，大约有 120 万人患有 COPD，其中大约 25-40% 的人体重不足，35% 的人的无脂肪质量指数非常低。建议测量他们的体重指数，医疗保健专业人员应努力确保 COPD 患者达到他们的营养需求。

一篇叙述性综述总结了 28 篇通过系统搜索数据库、灰色文献和手动搜索确定的 15 年原创文章的证据，重点关注两个主题，营养不良对 COPD 的影响，以及 COPD 营养不良的管理。

营养不良会对运动、肌肉功能和肺功能产生负面影响，并增加病情加重、死亡率和成本。管理选择包括可能增加体重和肌肉功能的营养补充剂。营养教育有短期的改善。

营养不良会影响 COPD 的多个方面，但治疗是有益的。临床实践应包括营养管理。
