Almost none!: Many people weigh 3 to 5 pounds lighter the day of their colonoscopy, but almost all the change is in loss of fluids, not body mass. As soon as you resume normal hydration and diet, the pounds return.

A 53-year-old female asked:
In the likely event that i will lose a considerable amt. of weight after my colonoscopy, will it be possible to keep some o it off with relative ease?

Probably not: Weight loss from fasting or clear liquid diets as well as colon cleansing vary dramatically among individuals. These days, in order to maximize the chances of a clean colon and good exam, endoscopists will recommend 2 or more days of clear liquids first. The resulting weight loss from all this might range from 3 to 7 pounds. But it's a LOT of water weight. Few experience permanent weight loss:)
