In brief: Gas = bad ultrasound

The reason why you are asked to not eat or drink anything many hours before an ultrasound is bowel gas.
When you eat or drink you also swallow air which ends up in your stomach and bowel. Ultrasound cannot penetrate through air and many abdominal organs will not be visualized on the exam rendering it technically difficult. Good luck.

In brief: Ultrasound

The rationale for having an empty stomach and bowels it too get the best possible picture with ultrasound technology.
It is common for the ordering physician to allow the patient to chew on ice chips to combat dry mouth before a procedure.
