IV fluids do not enter the stomach and so it does not contribute to the presence of any fluid in the stomach.
Water would empty by 2-3 hours from the stomach.
If it is just plain water, there is no need to worry as the endoscopist can suck out whatever little amount of water is present in the stomach with the help of the endoscope during the procedure and view the inner side of the stomach properly.
Thanks for the helpful reply regarding drinking water 2 hours before an endoscopy. I take it that even though the anesthesia will help to relax a patient during such a procedure, I wondered is it still okay for a patient to take their hypertension medication (such as IC Cartia 360 mg, Atenonlol 12.5 mg and Altace 10 mg.)? Would the pressure go to low with the anesthesia or go to high without the hypertension medications?
