Heartburn, also known as acid reflux, is a burning sensation in the chest caused by stomach acid flowing back into the esophagus. It can be a common and uncomfortable problem, but there are a number of things you can do to alleviate it.
Some simple lifestyle changes can help to reduce heartburn, such as eating smaller meals more frequently, avoiding lying down after eating, and elevating the head of your bed. You can also try avoiding foods that trigger your heartburn, such as spicy or fatty foods, and drinking plenty of water.
