Gastroparesis is a gastrointestinal motility disorder that refers to delayed gastric emptying in the absence of mechanical obstruction. Clinical manifestations include postprandial fullness and epigastric discomfort, abdominal distension, nausea, and vomiting. According to its etiology, it can be divided into three categories: surgery-related gastroparesis, non-surgery-related gastroparesis and idiopathic gastroparesis. Non-surgery-related gastroparesis is common clinically. At present, the exact pathogenesis of gastroparesis remains to be unclear. The intestinal flora is huge and abundant. It participates in a variety of physiological functions of the host. Studies have confirmed that the intestinal flora is related to perioperative treatment measures, surgical stress, and various system diseases (endocrine and metabolic system diseases, nervous system diseases, and immune system diseases), especially the weakening of gastrointestinal motility, and gastrointestinal motility. Attenuation can further promote the occurrence and development of gastroparesis. Based on the current research, this article reviews the research on the correlation between gastroparesis and intestinal flora.
