Burping, also known as belching or eructation, is one of the ways your body expels excessive gas from your stomach. It is often accompanied with a typical sound and, at times, an odor. The gas in your stomach may also cause abdominal pain and cramps that vary in severity and duration.
There are two main causes of burping – swallowing excess air while eating or poor digestion of food that results in an overproduction of gas in the digestive system.
