Heartburn is a common symptom during pregnancy. Changes in your hormones and body shape can contribute to acid reflux and heartburn. A few dietary and lifestyle changes can prevent and relieve symptoms.
Heartburn is when you have a burning feeling in your chest. The uncomfortable sensation can move up your throat. You may also have a bitter or sour taste in the back of your throat.
Though it’s called “heartburn,” it’s not related to your heart. It happens because of acid reflux, which occurs when stomach acid moves from your stomach up to your esophagus. The esophagus is the tube that carries food, liquid and saliva to your stomach.
A muscle called the lower esophageal sphincter (LES) sits between the esophagus and stomach. It opens to allow food to pass, then closes so acid doesn’t travel back up your esophagus. But if the LES doesn’t close properly, the acid can move into your esophagus, causing heartburn.
