Does it matter if you can’t drink 2000ml for a colonoscopy?

Before the colonoscopy generally need to drink 2000ml of intestinal cleansing medication, whether it has any effect if you don’t finish it needs to be judged according to the intestinal cleansing, if there is any fecal residue in the intestines it may affect the results of the colonoscopy.
Bowel cleansing medication can promote bowel movement and empty the intestines until the expelled feces is clear water. If the 2000ml of medication is not consumed but the feces is clear, it will not affect the results of the examination, but if the expelled feces is yellow water or contains fecal residue, it will affect the results of the colonoscopy.
It is recommended to follow the doctor’s instructions for bowel cleansing before colonoscopy, try to drink all the bowel cleansing medication, if you can’t drink all the medication and the bowel cleansing is not up to the standard, you can continue to cleanse through cleansing enemas.
