Dyspepsia, or functional dyspepsia, is a group of clinical syndromes characterized by postprandial fullness, bloating, mid-upper abdominal pain, and burning sensation in the mid-upper abdomen caused by gastric and duodenal dysfunction without organic disease. The etiology of functional dyspepsia includes gastric dysfunction and gastric tolerance diastole. Gastric motility disorders are mainly characterized by delayed gastric emptying and decreased gastric tolerance diastolic function. Gastric emptying time is significantly prolonged in patients with gastric motility disorders, and delayed gastric emptying is present in nearly 40% of the patient population. Delayed gastric emptying may be associated with symptoms such as nausea, postprandial fullness, and early satiety. Patients with gastric motility disorders show hypersensitivity to mechanical dilatation, which may be an important cause of dyspeptic symptoms such as postprandial abdominal pain, belching (burping), nausea, and fullness. Gastric tolerant diastole is the reflexive dilatation of the gastric fundus after eating to accommodate food and ensure that it is adequately digested in the stomach. Gastric permissive diastolic function is decreased in a significant proportion of patients with gastric motility disorders. It may be associated with the development of symptoms such as early satiety and loss of body mass. Repeated gastric functional dyspepsia, it is recommended to go to the hospital in time, under the guidance of the doctor to standardize the treatment.
