<P> Burping is generally caused by swallowing air when eating or drinking and subsequently expelling it , so in this case the expelled gas is mainly a mixture of nitrogen and oxygen . Burps can also be caused by drinking carbonated beverages , such as beer , soft drinks , energy drinks , and wine in which case the expelled gas is primarily carbon dioxide from the drink itself . Common diabetes drugs metformin and Byetta can cause burping , especially at higher doses . This often resolves in a few weeks . Burping combined with other symptoms such as dyspepsia , nausea and heartburn may be a sign of an ulcer or hiatal hernia , and should be reviewed by a physician . Other causes of burping include : food allergy , gallbladder problems , acid reflux disease , H. pylori , and gastritis . </P>
