Excessive burping is caused by swallowing excess air, chewing gum, carbonated drinks, constipation and lactose intolerance, according to Mayo Clinic. Other causes of burping are nervous habits and medical health problems such as a gallbladder problem or ulcers.
Also known as belching, burping is a voluntary or involuntary noisy release of the air from the stomach through the mouth, as stated by WebMD. It mostly occurs after eating. This condition is common in all people, but some people experience excessive burping. Reducing fatty foods, avoiding carbonated drinks, quitting smoking and eating slowly help reduce excessive burping. Treating heartburn with over-the-counter antacids is also necessary, notes Mayo Clinic.
