Frequent heartburn: Causes, triggers and impact on quality of life

Causes of heartburn
Stomach acid is normally blocked from entering the esophagus by the lower oesophageal sphincter (LOS). The LOS opens to let food and liquid pass from the esophagus into the stomach and remains closed between meals.2
