Understanding Burping: Types, Causes, and How to Manage It

Burping, also known as belching or eructation, is a natural bodily function that many of us experience daily. It’s the sudden escape of gas from the esophagus, causing an audible or silent release of air from the mouth or, sometimes, the nose. Have you ever wondered what causes burping and why it happens? In this article, we’ll delve into the fascinating world of burping, exploring its types, causes, and methods to manage it. Join us on this journey of understanding the science behind this common phenomenon.

Types of Burping:

  1. Gastric Burping Gastric burping is the most common type of burp, originating from the stomach. Every time you swallow food, a small amount of air enters your stomach, adding to a buildup of air. This accumulation causes both esophageal sphincters to relax, allowing air to escape upwards. The abdominal muscles, including the diaphragm and the front of the abdomen, push the air up the esophagus and out of the mouth or nose. The vibration of expelled air against certain structures in your upper airways creates the distinct burping noise. It’s entirely normal to experience gastric burping and you can have up to 30 burps a day.
  2. Supragastric Burping Supragastric burping, on the other hand, happens primarily above the stomach. During a deep breath, when the breathing muscle contracts, a negative pressure is created in the esophagus, similar to a vacuum. This leads to the relaxation of the lower esophageal sphincter, causing air to be sucked into the esophagus. In cases of supragastric burping, the lower sphincter remains closed, preventing air from entering the stomach. This trapped air creates pressure in the lower esophagus, and abdominal wall muscles help push the air back up and out of the mouth. Some individuals suffering from supragastric burping may burp hundreds of times a day.

Causes and Management:

The causes of burping can vary, and while occasional burping is normal, excessive burping can be a concern. For some, excessive burping might be due to a condition called aerophagia, where individuals swallow excessive air, leading to bloating and frequent burping. Adequate sleep and dietary adjustments, such as reducing sugar and starch intake, can help manage burping. However, for those experiencing frequent supragastric burping, there are strategies to find relief.

One approach is cognitive behavioral therapy, which can help individuals gain better control over their burping. Special exercises targeting the diaphragm, the muscle responsible for breathing, can also be effective in managing supragastric burping.


In conclusion, burping is a natural and common occurrence that can be categorized into two main types: gastric burping and supragastric burping. While gastric burping is a normal bodily function, supragastric burping can be more challenging to manage for those who experience it excessively. Understanding the causes and the available management techniques can provide much-needed relief for individuals dealing with frequent burping.
