This works somewhat similar to the pressure-relief-valve found on pressure cookers to let go of excessive pressure build-up. In general, belching helps to reduce discomfort from gaseous distension. However, if this happens too frequently, it can result in disturbing symptoms such as heartburn, chest pain, painful or difficult swallowing, complications from acid burns might have developed in your oesophagus.
