Non-Pharmacological Management of Gastroparesis
A low-fiber, low-fat diet with small, frequent meals (5-6 per day) and increased proportion of liquid calories is the cornerstone of non-pharmacological management for gastroparesis. 1, 2
Dietary Modifications
Dietary management is the primary non-pharmacological approach for gastroparesis:
Meal structure modifications:
Food composition adjustments:
Stepwise nutritional approach for severe cases:
- Modified solid foods
- Blended/pureed foods
- Liquid diet with oral nutritional supplements
- Enteral nutrition via jejunostomy tube (for severe cases) 2
Medication Adjustments
Withdraw medications that delay gastric emptying:
Consider diabetes medications with neutral effect on gastric emptying:
- DPP-4 inhibitors
- Sulfonylureas
- Thiazolidinediones 2
Glycemic Control
- Achieve near-normal glycemic control to prevent progression of gastroparesis 2
- Adjust insulin timing and dosage to account for delayed gastric emptying 2
Surgical and Interventional Options for Refractory Cases
For patients with severe, refractory gastroparesis who have failed standard medical therapy:
Gastric electrical stimulation (GES):
- FDA-approved for treating refractory gastroparesis
- Most effective for nausea and vomiting symptoms
- Not effective for accelerating gastric emptying
- Contraindicated in patients with predominant abdominal pain or current opioid use 2
Gastric peroral endoscopic myotomy (G-POEM):
- May be considered for patients with severe delay in gastric emptying
- Evidence level is low 2
Enteral nutrition via jejunostomy tube:
Practical Implementation Tips
- Start with the least restrictive dietary modifications and progress as needed
- Monitor nutritional status, electrolytes, and hydration regularly 2
- Maintain a food diary to identify specific food triggers
- Consume the majority of daily calories earlier in the day
- Remain upright for 1-2 hours after meals to aid gastric emptying
- Avoid carbonated beverages that can cause gastric distension
Common Pitfalls and Caveats
- Avoid overly restrictive diets that may lead to nutritional deficiencies
- Don't neglect glycemic control in diabetic gastroparesis, as hyperglycemia can worsen gastric emptying
- Consider psychological support as gastroparesis significantly impacts quality of life 4
- Regular reassessment is crucial as symptoms and severity may fluctuate over time
- Recognize when to escalate care - persistent vomiting, weight loss >10%, or inability to maintain hydration may require more aggressive interventions
The American Diabetes Association and American Gastroenterological Association emphasize that dietary management should be the first-line approach for most patients with gastroparesis, with more invasive interventions reserved for refractory cases 1, 2.
