What nationality is most affected by heartburn?

Heartburn is a common condition that affects people worldwide, but its prevalence can vary by region and lifestyle factors. In the United States, for instance, studies indicate that a significant portion of the adult population experiences heartburn regularly, often linked to diet, obesity, and stress. Other countries with similar lifestyle factors, such as those in Western Europe, also report high rates of heartburn. However, specific nationality statistics may not be consistently available, as heartburn can be influenced by various cultural and dietary habits.
