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

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

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

Need to examine: Unintended weight loss need to be evaluated by a physician by taking history, physical examination and may be some tests. It would be prudent to consult your doctor as it is not feasible to provide a meaningful opinion without examining you.

Had clear colonoscopy but still lots of pain and lose stools also blood in toilet this week?

Diverticulosis: You may have diverticulosis pouches which are a common cause of loose stools and passage of bright red blood. I assume that inflammatory colon changes were not seen, but check with your colonoscopist to see whether diverticulosis of the colon may be present even with your "normal" colonoscopy. ...Read more

Had a colonoscopy done on the 8th of may and I feel bloated and I've lost weight should I be concerned? Should I go see my doctor?

5wks post op GB removal. Had a colonoscopy and endoscopy and all normal. Still very nauseous most of time. Healthy diet and weight. What could it be?

Some patients react: To the type of anesthesia used during the procedure that can remain in your system for a few weeks. More than likely you are responding the air they had to use to visualize your gallbladder and that gets resorbed in time, and you should be feeling better daily. If not, call your surgeon and ask her/him what gives? They will help you out too. ...Read more

My son was told after a colonoscopy, that his small intestines were on one side of his body and his colon on the other. His birth weight was only 4lbs and 5 oz. Born only two weeks early he was considered full term. Can this cause problems later?

My son was told after a colonoscopy, that his small intestines were on one side of his body and his colon on the other. His birth weight was only 4lbs and 5 oz. Born only two weeks early he was considered full term. Can this cause problems later?

Hard to know: The colon is part of your intestine so I'm not sure what your son was really told. I suspect that he was told he has a malrotation (though this is difficult to tell from colonoscopy). This is a dangerous condition and needs to be surgically corrected asap- to be able to say more i'd need to know the medical terms that were used. ...Read more

In my 30s.Eat healthy diet, normal weight, exercise. Have had 5 colon polyps removed between my last 2 colonoscopies? 4 benign, 1 tubular adenoma. Common?

Follow-up care: Colon polyps are not normal, but it is good that you had colonoscopy to have these removed. Do you have family history of colon cancer? Even if you do not, do follow your doctor's advice for follow-up colonoscopy at no more than five years from now.

I was diagnosed w IBS from a lower colonoscopy. I have been living with diarrhea over the last year. Now I have a rash all over my skin & lost weight?

I was diagnosed w IBS from a lower colonoscopy. I have been living with diarrhea over the last year. Now I have a rash all over my skin & lost weight?

Probably not related: .... unless you were given a prescription drug for the IBS that may be causing the rash. Important clues about what might be going on will come from someone looking closely at the rash and taking a diet and symptom history to try to ascertain why you might be losing weight. Keep working with your doctor to sort through these significant problems. Best wishes:) ...Read more

My mother have been loosing weight the last year, she is down to 46 KG now. They did scan's, blood work and colonoscopy, found nothing wrong, she eats healthy but is still loosing weight. She is not ill, just complains about her bones hurting.

My mother have been loosing weight the last year, she is down to 46 KG now. They did scan's, blood work and colonoscopy, found nothing wrong, she eats healthy but is still loosing weight. She is not ill, just complains about her bones hurting.

Keep investigating.: Investigation into cause needs to continue here. Her weight loss sounds significant, and she does have symptoms which could be targeted for testing. Unintentional weight loss could be a harbinger of a significant underlying issue which needs to be elucidated. Her bone pain may be the hint that we need to solidify a diagnosis. ...Read more
