Gastroparesis and SIBO: When Your Stomach Empties Too Slowly
Gastroparesis affects up to 5 percent of the population and creates a backup effect that promotes bacterial overgrowth. Nausea, early fullness, and food sitting in the stomach for hours are hallmark symptoms.
Current Consensus
- Gastroparesis is defined as more than 10 percent meal retention at 4 hours on gastric emptying scintigraphy.
- Prevalence is estimated at 2 to 5 percent, with a 4:1 female predominance.
- A normal endoscopy does NOT rule out gastroparesis.
- Common causes include diabetic neuropathy, post-viral nerve damage, and post-surgical complications.
Open Questions
- The clinical significance of mild gastroparesis in SIBO development.
- The optimal dietary strategy for managing concurrent gastroparesis and SIBO.
