The most common cause of burping and belching after eating may be over-eating, commonly known as burping. It may also be that you are eating at a faster pace, or talking while eating, and that you are inhaling too much air into your stomach while eating. At this point, burping and belching are needed to get rid of the excess gas, and often the more gas that enters the stomach, the longer the burping will take. If you are stimulated by cold or spicy foods, this may also cause hiccups, and restlessness can also cause hiccups. Of course, hiccups and belching after meals can also occur if you have gastrointestinal disorders. The most common disorder is functional dyspepsia, which can also be seen in diseases such as gastroesophageal reflux disease, peptic ulcer, and pyloric obstruction.
