How to Relieve Excessive Burping: Excessive burping can be caused by a variety of factors, including diet, stress, and digestive issues. To relieve this discomfort, start by avoiding carbonated beverages, chewing gum, and foods that are known to cause gas, like beans or broccoli. Try eating smaller meals throughout the day, rather than large meals, to help ease digestion. Drinking peppermint tea or taking digestive enzymes can also help to soothe the digestive system and reduce gas.
