Patient-Friendly Explanation

When someone has both COPD and excess weight, breathing takes more effort and exercise becomes harder, which can lead to a spiral of inactivity. Losing fat can improve breathlessness and stamina, but losing muscle is dangerous in lung disease. Weight management therefore has to be gradual and high in protein.

Clinical Definition

Obesity in COPD increases dyspnoea and oxygen demand, reduces functional residual capacity and expiratory reserve volume, and impairs exercise tolerance, while mild-to-moderate obesity has been associated with lower mortality in some COPD cohorts — the obesity paradox. Weight loss must be approached carefully because low fat-free mass is an independent predictor of mortality in COPD. Management combines pulmonary rehabilitation, protein-adequate energy restriction and resistance training, with attention to coexisting obstructive sleep apnoea.

Why It Matters

In COPD the target is fat loss with muscle preservation, not weight loss at any cost. NuLifeCare Singapore works alongside respiratory care to set safe rates of loss and protein targets.
