A normal endoscopy does not measure how fast the stomach empties
Structural tests can look normal when gastric emptying or stomach accommodation is impaired.
Several explanations may be worth exploring
- Functional dyspepsiaImpaired gastric accommodation or sensitivity can cause early fullness without visible lesions.
- GastroparesisDelayed gastric emptying may cause nausea, vomiting and post-meal retention.
- Medication-associated slowingOpioids and some other medicines can reduce gastric motility.
- Diet-related or bowel interactionMeal size, constipation and bowel symptoms can amplify upper-abdominal fullness.
