Patient-Friendly Explanation

Atrial fibrillation (AF) is an irregular and often fast heartbeat. Being overweight or obese makes AF more likely because excess weight changes the structure of the heart and raises blood pressure. Losing weight can reduce symptoms and the risk of AF returning.

Clinical Definition

Obesity is an independent risk factor for atrial fibrillation, mediated by left atrial enlargement, epicardial adipose tissue, elevated filling pressures and autonomic remodelling. Sustained weight loss of 10 percent or more is associated with reduced AF burden, improved ablation outcomes and reversal of atrial remodelling.

Why It Matters

Weight management is now a recognised pillar of AF care alongside rate and rhythm control. The NuLifeCare Singapore medically supervised weight-loss programme can help patients with AF achieve the sustained weight reduction that supports heart health.
