Gastroparesis in Diabetes Mellitus: After Glucose Control and Dietary Management Have Not Relieved Symptoms

This protocol covers the next step for a patient with diabetic gastroparesis whose symptoms and gastric emptying have not adequately responded to first-line optimisation of glucose control and dietary management.

Clinical Scenario

Gastroparesis occurring in a patient with diabetes mellitus. Optimal glucose control remains important to reduce the future risk of aggravation of gastroparesis, but when first-line measures prove insufficient, additional management is required.

Previous Line Did Not Meet Goals

The prior approach — optimal glucose control together with dietary management (small-particle, low-fat diet) — did not achieve its targets of symptom relief and enhanced gastric emptying. This protocol defines the next line of management.

Next-Line Approach (Partial Overview)

The next step introduces pharmacologic treatment directed at improving gastric emptying and reducing gastroparesis symptoms, drawing from several distinct drug classes and modalities. For patients with diabetic gastroparesis specifically, an adjunctive approach may also contribute to symptom control. The full agent selection, sequencing criteria, and clinical targets are set out in the complete structured regimen.

In patients with diabetic gastroparesis (DG), optimal glucose control is suggested to reduce the future risk of aggravation of GP (conditional recommendation, low level of evidence).

In patients with idiopathic and DG, pharmacologic treatment should be considered to improve GE and GP symptoms, considering benefits and risks of treatment (conditional recommendation, low quality of evidence).

Acupuncture alone or acupuncture combined with prokinetic drugs may be beneficial for symptom control in patients with DG. Acupuncture cannot be recommended as beneficial for other etiologies of gastroparesis.
