Summary
We include products we think are useful for our readers. If you buy through links on this page, we may earn a small commission. Here’s our process. Heartburn and nausea are both common gastrointestinal complaints, which means they have to do with the digestive system. Heartburn is also called gastroesophageal reflux. It has nothing to do with the heart. Rather, it occurs when acid from the stomach flows backward into the esophagus — the tube that connects the throat to the stomach. People often describe heartburn as a burning sensation just behind the breastbone.
