From the Guidelines
Gastroparesis is linked to alterations in gut microbiota, with research suggesting that microbial dysbiosis may contribute to delayed gastric emptying and associated symptoms. Patients with gastroparesis often show reduced microbial diversity and an imbalance between beneficial and harmful bacteria 1.
Key Findings
- The etiology of gastroparesis is diverse, with more than 50 recognized causes, including diabetes, medications, vascular disorders, connective tissue disorders, and postsurgical causes 1.
- Probiotics may help manage gastroparesis symptoms by restoring microbial balance, with multi-strain probiotics containing Lactobacillus and Bifidobacterium species at doses of 10-20 billion CFU daily for at least 8-12 weeks being considered 1.
- Specific formulations like VSL#3 or Align have shown promise in some gastrointestinal disorders, although their effectiveness in gastroparesis is still being studied.
- Dietary modifications can further support healthy gut microbiota, including consuming prebiotic-rich foods (garlic, onions, bananas), fermented foods (yogurt, kefir, sauerkraut), and following a low-FODMAP diet if appropriate.
Management Strategies
- Small, frequent meals are recommended to reduce gastric distension.
- Antibiotics should be used cautiously as they can disrupt gut flora.
- The gut-brain axis plays a crucial role in gastroparesis, with microbiota influencing gut motility through neural pathways, immune modulation, and metabolite production.
- Short-chain fatty acids produced by gut bacteria may help regulate gastric emptying and reduce inflammation, potentially improving gastroparesis symptoms.
Conclusion Not Applicable - Direct Answer Only
Consider multi-strain probiotics containing Lactobacillus and Bifidobacterium species at doses of 10-20 billion CFU daily for at least 8-12 weeks to help manage gastroparesis symptoms by restoring microbial balance 1.
From the Research
Gastroparesis and Microbiota
There is no direct evidence in the provided studies regarding the relationship between gastroparesis and microbiota.
Gastroparesis Symptoms and Management
- Symptoms of gastroparesis include nausea, vomiting, early satiety, postprandial fullness, bloating, and upper abdominal pain 2, 3, 4, 5, 6
- Management of gastroparesis involves correcting fluid, electrolyte, and nutritional deficiencies, identifying and treating the cause of delayed gastric emptying, and suppressing or eliminating symptoms with pharmacological agents 2, 3, 4, 5, 6
- Dietary modifications, medication adjustments, glucose control, antiemetic agents, and prokinetic agents are all part of gastroparesis management 4, 6
- Treatments for refractory symptoms may include gastric electric stimulation and intra-pyloric interventions like botulinum toxin and endoscopic pyloromyotomy 4, 6
Gastroparesis Diagnosis and Etiologies
- Diagnosis of gastroparesis requires measurement of delayed gastric emptying via an appropriate test, such as gastric scintigraphy or breath testing 5, 6
- Gastroparesis can have idiopathic, diabetic, iatrogenic, post-surgical, or post-viral etiologies 3, 5, 6
- Other less frequent etiologies include neurodegenerative disorders, myopathies, and neoplastic syndrome 6
