Gastric Emptying Calculator
Calculate gastric emptying percentages with automatic decay correction for solid and liquid phases. Adapted from this spreadsheet
Solid Phase Gastric Emptying
Enter observed counts for each time point (0-240 minutes)

Normal Reference Ranges
Solid Phase
- • 30 min: Rapid if < 70% remaining
- • 60 min: Rapid if < 30%, Delayed if > 90%
- • 120 min: Normal if < 50%
- • 180 min: Normal if < 21%
- • 240 min: Normal if < 10%
Liquid Phase
- • 30 min: Normal if < 50% remaining
- • Liquid typically empties faster than solids
- • Most liquid should empty within 60-90 minutes
