Belching

Belching is the release of gas from the digestive tract through the mouth. It is often accompanied by a sound and may be involuntary or voluntary. Belching typically occurs after eating or drinking, but can also occur due to the buildup of swallowed air. It can be accompanied by abdominal bloating, cramps, or a sour taste in the mouth. Belching can be a sign of digestive issues such as acid reflux, indigestion, or other gastrointestinal issues.
