Heartburn occurs when stomach acid rises into your esophagus. Normally when you swallow, your lower esophageal sphincter (LES) relaxes, allowing liquid to flow into your stomach, before closing again.3,4

If the LES relaxes abnormally, acid can flow back up into your esophagus and cause heartburn.5

Get your facts straight on these common heartburn myths.

Everyone has the same heartburn triggers.

Triggers differ from person to person. It all comes down to how your body reacts to certain foods, other medications you may be taking, your lifestyle, weight, pregnancy, and medical conditions.3,7-10

You can only get heartburn from eating certain foods.

Triggers differ from person to person. For some people, foods may be that trigger. But for others, the root cause may be physiological or environmental. If you think a certain food may be a trigger, keep tabs on what you eat and drink so you can learn how to avoid the things that trigger heartburn in your body.9

If you have bad breath, it means you have acid reflux.

Bad breath is one indicator of acid reflux, but it’s not usually the only symptom. Other heartburn symptoms will likely include an uncomfortable burning sensation in your chest or throat.7
