Belching is what everyday people call burping, and there are many reasons for it, including functional and organic. Functional belching is not a big deal, such as dyspepsia, and the Rome III criteria divide functional gastroduodenal diseases into 3 major categories: 1) functional dyspepsia, which is indigestion of the gastrointestinal tract; 2) belching; and 3) nausea and vomiting. These are the symptoms that the people usually say, there is no major disease, so it is called functional. Functional generally speaking, symptomatic treatment can be, such as indigestion, take some drugs to help digestion, nausea, vomiting, a little antiemetic drugs or observation of more water can be. If you can’t do a gastroscopy, you can do a barium meal to find out if there is any damage to the gastric mucosa, gastric ulcer, gastroduodenal ulcer, pancreatic disease, biliary tract disease, and generally more diseases of the digestive tract. There are also neurological belching. Some people feel nervous and uncomfortable, and they have belching. If these are neurological or functional, they should be observed and not treated, but if they are organic and cause belching, they should be seen by a hospital and treated accordingly.
