Fasting abdominal ultrasound allows clear visualisation of liver, gallbladder, pancreas and kidneys. Proper preparation is key for sharp images.

Key takeaways
- Fasting avoids gas and intestinal contractions
- Test duration: 15-30 minutes
- No radiation, painless, safe
- Avoid chewing gum beforehand
- Water hydration is allowed
Why fasting
Eating produces gas in the GI tract that hinders ultrasound vision. 6-8 hours fasting allows full gallbladder visualisation and avoids interference.
How to prepare
- 6-8 hours fasting (no food or sugary drinks)
- Small amounts of water allowed
- Keep usual medication unless told otherwise
- Comfortable clothes
- Bring recent medical reports
