Is it true that some people get colonoscopies, just to lose weight or get them because they can't go poop for a while..?

Not to lose weight: I am not aware of colonoscopies being performed for weight loss purposes. However worsening constipation in the right clinical context is an indication for diagnostic colonoscopy. ...Read more

How much weight can you lose from a colonoscopy pr?

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. ...Read more

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?

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:) ...Read more

Is weight gain normal after colonoscopy ? I had procedure yesterday and today the scale shows I've gained 3 lbs

Is weight gain normal after colonoscopy ? I had procedure yesterday and today the scale shows I've gained 3 lbs

Unlikely, but . . .: Prior to colonoscopy, one has to drink lots of icky fluids to clean out bowel. As a result, one usually loses weight. OTOH 3# weight gain in one day could be from bloating unrelated to procedure. Or more likely, use of different scales at different times of day in different amounts of clothing. Be sure to pay more attention to how your clothes fit than actual weight (using same scale at same time) ...Read more

Movement of gas: Given the information you provided, your sensation is likely to be due to movement of gas in the colon. You may try to vary your diet to see if that makes a difference. Drink enough water so that bowel contents do not become thick. ...Read more

I had a colonoscopy 2 days ago how long should i wait before lifting weights again? The doctor told me 10 days but that seems a bit long

You are fine, now: Colonoscopy has very little if any after effects. Nearly all subjects are back to normal work next day. So you do not need to have any restrictions after 2-3 days that it takes to fully recover from all the bowel prep -related fluid imbalance. So you are ready to do everything from tomorrow on wards. ...Read more

Constipated badly last 6 mths. Lost about 10lbs in weight without trying in last 6 months. Had colonoscopy last year. All ok. Pressure under left rib ?

Difficult to know: Your constipation & weight loss might not be related. Your colonoscopy that is done to screen for colon cancer is reassuring. Your constipation could be due to low fiber/fluid intake or drug side effects. It’s also unusual to lose weight without trying unless you are not eating much or have a bad appetite because of the constipation. Pressure under rib could be a muscle spasm or something serious. ...Read more
