Eructing is a term used to describe the act of burping, or belching, after consuming food or drink. Synonyms for this word include belching, burping, regurgitating, expelling gas, and releasing air from the stomach. Other words that can be used to describe the same action include gurgling, rumbling, bubbling, and churning. While such actions may seem unpleasant to many, they are actually a natural part of the digestive process and help to release air from the stomach. It is important to note, however, that excessive eructing or belching may indicate a medical condition such as acid reflux or gastroesophageal reflux disease (GERD) and should be addressed by a healthcare professional.
