What is acid breakthrough?
At times, even while taking prescription heartburn medications, acidic gastric juices can flow up from your stomach into your esophagus (food pipe) through a valve called the lower esophageal sphincter. This acid reflux irritates the sensitive tissue that lines your esophagus. It’s important to talk to your healthcare professional about all the symptoms you feel in your stomach, chest and throat, because heartburn symptoms can appear as different sensations.
