The cardiac sphincter, also known as the lower esophageal sphincter, is a muscular valve that controls the flow of food from the esophagus to the stomach. Issues with this sphincter, such as dysfunction or reflux of stomach acid into the esophagus (heartburn), can lead to complications but are typically not life-threatening by themselves. However, severe and chronic cases can contribute to conditions that may lead to serious health problems over time.
