If these symptoms occur, be aware! It could be a functional gastrointestinal disorder.

　　In medicine, diseases can be classified as organic and functional. Organic gastrointestinal diseases are real lesions found in tissues or organs through examination, such as inflammation, tumor, ulcer, polyps, etc. Functional gastrointestinal diseases are those in which no abnormality has been found in various tests, but the symptoms of digestive tract are real and cannot be explained by organic lesions or biochemical abnormalities.

　　The incidence of functional gastrointestinal diseases is very high in digestive system diseases, which seriously affects people's quality of life. Functional gastrointestinal diseases mainly include: functional heartburn, functional chest pain, globus hysteria, functional dyspepsia, irritable bowel syndrome, functional abdominal distension, functional constipation, functional diarrhea and functional abdominal pain syndrome. Among them, functional heartburn, functional dyspepsia and irritable bowel syndrome were the most common.

　　Patients with esophageal symptoms: feel a burning sensation in the back of the sternum, which is heartburn or even pain, similar to angina pectoris, feel the stomach contents into the esophagus and even the pharynx and mouth, common in functional heartburn;

　　The above digestive tract mainly: stomach like gas, belching, belching, or burning pain, pantothenic acid, loss of appetite, nausea, vomiting and other abdominal discomfort symptoms, common in functional dyspepsia;

　　The following digestive tract mainly: constipation or diarrhea, can be relieved after defecation, intestinal examination did not find the problem, common in irritable bowel syndrome, functional constipation, functional diarrhea.

　　Because the digestive tract is a complete system, symptoms often overlap between different diseases. In addition, functional gastrointestinal diseases have the characteristics of long course, slow onset, intermittent attack, accompanied by psychological disorders and emotional fluctuations, which are similar to the symptoms of other diseases, so it is very difficult to diagnose them in medicine.

　　The biofeedback gastrointestinal motility instrument of Kuanchen Technology automatically collects human gastrointestinal electrical signals by applying electrodes to the gastrointestinal pacemaker on the body surface. The collected gastrointestinal electrical signals are calculated and analyzed by special software to objectively reflect the gastrointestinal peristalsis of patients and the strength of gastrointestinal motility. This diagnostic method is non-invasive, painless and has no side effects. It can be cross-referenced with morphological examination such as gastrointestinal endoscopy and X-ray barium meal, and provide objective basis for comprehensive diagnosis, treatment and evaluation of curative effect of gastrointestinal diseases.
