Welcome to the forum. Some amount of salt and water is reabsorbed in the bowel but alcohol interferes with
this and may cause diarrhea. This interferes with colonoscopy. Moreover alcohol often causes gastritis which
also interferes with a clear field of vision of the colonoscope. Thirdly alcohol interferes and interacts with
the medicines that are given before and during the procedure. Lastly alcohol can cause you to lose more fluids
especially from your urine. A gastroenterologist needs a clean and empty colon for a clear picture. Otherwise,
you may have to get a repeat colonoscopy done. So it is advisable to avoid alcohol consumption atleast 24
hours before the procedure. I hope it helps. Take care and please do keep us posted in case you have any
additional doubts. Kind regards. You can find more relevant information about this on the following site: http://www.colonoscopyprep.info/following-the-diet-before-colonoscopy-bowel-preparation/

Hi! Dr Anand has explained everything very well. Apart from the reasons cited by Dr Anand, alcohol may
interfere with the sedatives given for the procedure. Alcohol may cause hangover and the combined effect of
the hangover and sleepiness due to fluid loss from the procedure and sedatives may not be good. Also alcohol
may interfere with bowel preparation. Hope this helps. Please let me know if there is any thing else and do
keep me posted. Take care!
