Abstract:
Pulmonary rehabilitation (PR) increases exercise capacity, reduces dyspnea, and improves quality of life (QoL) in patients with chronic obstructive pulmonary disease (COPD). Patients requiring PR can present with multiple comorbidities. One of the most common comorbidities is obesity. The prevalence of obesity in patients with COPD is increasing at an alarming rate. To date the efficacy of PR to ameliorate obesity in patients with COPD is unclear. Obesity in patients with COPD is associated with increased morbidity and mortality compared to patients without obesity. However, the benefits of obesity paradox in lower mortality rate health-related QoL and health care utilization remain unclear. This review discusses the challenges of prescribing PR to patients with obesity and COPD. In addition, the definition of and the potential challenges and benefits of the obesity paradox in patients with COPD will be discussed. Treatment strategies that include combining PR with lifestyle management, individually tailored nutritional advice, pharmacotherapy, and surgery need to be tested in prospective, randomized controlled trials. The challenges of providing complex care, prioritizing patient needs, and future directions will also be discussed for patients with obesity and COPD.

Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
