Clinical evidence

Designed to deliver durable relief from nausea & vomiting

A number of key clinical studies involving diabetic and idiopathic gastroparesis patients receiving Enterra® Therapy resulted in significant nausea and vomiting symptom improvements.

Additional clinical studies

Enterra Therapy supported by practice guidelines

AGA best practices review (2021)

“Enterra Therapy does improve refractory nausea and vomiting in some patients with gastroparesis and may improve glycemic control, nutritional status, and quality of life, while reducing hospitalizations and medication use.”5

ACG guidelines (2022)

“Gastric Electric Stimulation (GES) may be considered for control of GP symptoms as a Humanitarian Use Device (HUD).”6

Enterra Therapy for treatment of chronic, resistant to medication nausea and vomiting associated with gastroparesis caused by diabetes or an unknown origin in patients aged 18 to 70 years: patients should always discuss potential risks and benefits of the device with their physician.


Authorized by Federal law for use in the treatment of chronic intractable (drug refractory) nausea and vomiting secondary to gastroparesis of diabetic or idiopathic etiology in patients aged 18 to 70 years. The effectiveness of this device for this use has not been demonstrated. What does this mean?
