Forum Name: Liver Diseases

Question: RUQ Ultrasound


 rswaney - Tue Dec 27, 2005 8:04 pm

I'm scheduled for an RUQ Ultrasound to check for liver problems.

Why can't I eat or drink anything after midnight?

I especially don't understand why I can't drink water?

Thank you,
Russ

User avatar Hi Russ,

The reason you cannot eat or drink anything is because when food/liquid enter your stomach sends a signal to start secretion of enzymes used to aid digestion. When this occurs bile gases are produced. Bile gases crowd the abdominal area/organs. This inhibits visualization of your organs during an ultrasound.

Hope this answers your question.
