Global GERD Prevalence: 1 in 7 Adults Worldwide Affected
How Common Is GERD Around the World?
Gastroesophageal reflux disease affects approximately 13.98% of adults globally, meaning roughly 1 in 7 people worldwide experience this condition. This comprehensive meta-analysis of 73 studies across multiple continents reveals significant regional variations, with North America showing the highest prevalence rates and East Asia the lowest.
Dr. Kumar’s Take
This global analysis confirms what we see clinically - GERD is incredibly common and varies dramatically by geography and lifestyle factors. The 14% global prevalence means nearly 1 billion people deal with reflux symptoms regularly. Most importantly, the regional differences point to modifiable risk factors like diet, obesity rates, and lifestyle patterns that we can actually address to reduce GERD burden.
