Heartburn is a burning pain in the chest, immediately behind the breast. The pain is caused by gastric acid moving to the throat (acid reflux). The hearing often gets worse after eating, especially in the evening, or when lying or bending.
Heartburn has no obvious cause, but some factors that may affect it are foods (such as coffee, tomato, alcohol, chocolate and fat or spicy foods), overweight, smoking, pregnancy, stress, anxiety, gastric ulcer and bacterial infection.
