The most common causes of belching are eating or drinking too quickly, drinking carbonated water, and anxiety, states Healthline. Other causes include swallowing air, consuming foods that cause frequent belching or gas, medications, and medical conditions that cause the stomach acid to flow upwards into the esophagus.
Belching, burping or eructation is the act of expelling excessive air from the stomach through the mouth, explains Healthline. Normal belching is a natural action that has no consequences and does not require any treatment. A person may control or prevent belching by sitting down to his meals, eating more slowly, avoiding carbonated drinks, taking probiotic supplements and avoiding anxiety-inducing situations.
