EGDs, ERCPs and endoscopic ultrasounds

 

Since these procedures involve passing a scope into your stomach and small intestine, there is not a prep (ie laxative) that you have to drink ahead of time.  Your stomach clears itself as long as you have not eaten for several hours before the procedure.  Do not eat anything after midnight the night before your procedure.  Stop drinking anything, including water, 8 hours before the procedure.  And please do not eat a large meal before you have to fast for the procedure
