Heartburn is a burning sensation or pain in your chest behind your breastbone. The burning feeling starts in the upper abdomen and moves up to the chest. It usually happens after eating and gets worse when you bend over or lay down. Heartburn might be accompanied with many other symptoms such as bloating, dyspepsia and sour taste in your mouth.

At the lower end of your esophagus, there’s a ring of muscle, known as esophageal sphincter which contracts every time when food travels from your esophagus to the stomach. It keeps the stomach contents in place and prevents the gastric acid to flow back. However, the sphincter may become weak or relaxed at the wrong time and not close properly. This allows the stomach content to regurgitate into your esophagus which irritates the esophagus lining and causes a burning sensation.

The causes of heartburn may vary from person to person. Obesity, smoking and alcohol consumption, pregnancy all may trigger heartburn. Acidic, fatty and spicy foods can also weaken your esophageal sphincter and produce excess acid in your stomach.
Work with your doctor to monitor and examine your lifestyle and eating habits. You could be able to identify and eliminate these triggers and stop the heartburn.
