Background and Aim Delayed gastric emptying occurs in more than 50% of chronic diabetic patients, and this is associated with significant impairments in quality of life. Traditional therapy for delayed gastric emptying has focused on supportive treatment, and there is no significant effective therapy. The effect of low‐energy shock wave on gastric motility is never studied. We investigated low‐energy shock wave on gastric motility in a diabetic rat model. Methods Twenty‐eight male Wistar rats were studied and separated in three groups in randomized order as control, diabetic rats received shock wave, and diabetic rats received the sham procedure. Antral area and motility were recorded using the transabdominal ultrasound. Blood was taken for measurement of gastric motility peptides. Subjects were killed for immunohistochemical stain analysis of enteric plexus of the stomach. Results We successfully induced 20 diabetic rats and set ultrasound for measuring rat gastric contract and emptying model and demonstrated that 6 weeks of low‐energy shock wave could promote gastric contraction and emptying in diabetic rats. Moreover, we demonstrated that shock wave could increase defecation and feces and decrease serum cholesterol and triglycerol. However, no effect on glycohemoglobin and gastric motility peptides was recorded. In the immunohistochemical staining, shock wave increased expression of gastric myenteric neuron plexus. Conclusion Low‐energy shock wave can increase gastric contraction and emptying by activating axonal regeneration and increasing myenteric plexus, but not related with motility peptides.
