Atrial Fibrillation: Nigeria's Most Common Dangerous Heart Rhythm Problem

The Irregular Heartbeat You Shouldn't Ignore

Atrial fibrillation (AF) — a chaotic, irregular heart rhythm originating in the upper chambers — is the most common significant cardiac arrhythmia worldwide, and its prevalence is rising sharply in Nigeria with increasing hypertension, obesity, and metabolic syndrome rates. AF dramatically increases stroke risk: pooled blood in the fibrillating atrium forms clots that can travel to the brain.

Root Causes in the Nigerian Context

• Hypertension — the single biggest driver of AF in Nigeria; stretches atrial walls and disrupts electrical conduction
• Obesity — visceral fat produces inflammatory cytokines that damage atrial tissue
• Obstructive sleep apnoea — oxygen dips during sleep trigger AF; common and underdiagnosed in Lagos
• Excessive alcohol — acute AF after heavy drinking ("holiday heart") and chronic AF with regular use
• Thyroid disease — hyperthyroidism directly causes AF; thyroid screening is essential
• Magnesium deficiency — magnesium stabilises cardiac electrical activity; deficiency is common

FXMed's Approach to AF

Our Functional Health Analysis includes thyroid panel, magnesium, inflammatory markers, sleep assessment, and advanced cardiovascular risk. Our nutrition and lifestyle protocols target the hypertension, obesity, and inflammation that perpetuate AF.
