I am going to see my GI specialist in a couple of weeks and I suspect she is going to want to do a colonoscopy.I had one about 12 years ago and it showed nothing. Here is my question, for those with LG, has ANYONE had a colonoscopy that actually showed anything relative to LG?I am asking because I think this is not the correct procedure to do for LG and don't want to have to go through it if it is pointless anyway.

For once, you are correct.

I had one a couple of years ago. GI found nothing wrong. It probably won't help solve the LG, but it might be worth going through just to make sure there are no other problems. It might ease your mind a little bit. Take care!IBS C/D and LG 23 years

I'm with flux. I would expect the colonoscopy would not be the correct test for LGers.Going through all the various thoughts of what is going on with LG peeps.If it is some abnormal gas of some sort:For the colonoscopy they fill you up with air to expand the colon so they can see the lining well. If there was abnormal gas in there it might be diluted out assuming anything was left in there after your clean out and what was in there when all cleaned out was the same as normal.Additionally it isn't something you could see or biopsy for so it wouldn't be useful for that.They would need to collect gas under normal conditions (not full colon cleaned out ones) and put it in a machine that analyzes which gas molecules are in the sample.If it is abnormal bacteria of some sort.Same deal, you won't see them visually nor would they see it in biopsy and they don't go to the part of the small intestine you take samples for SIBO, either. A lot of the bacteria in there (which may be disrupted by the prep anyway) are not easy to culture so it is hard to know if the only bacteria involved would be ones you could culture and see what was going on. Usually the culture colon bacteria from stool samples and small intestinal bacteria by going in from the top.Sphincter abnormalities.Most of these are not an anatomical difference you can see. It tends to be more of a functional thing that a physically obvious anatomical one. You would need a test like manometry or defagraphy to see if it was functioning properly.Other odor causing disorders:Colonoscopy will not test for any of those. Usually you are looking at urine or blood tests or other things that tell you about physiology (what is going on with the chemistry inside the body). Colonoscopies tell you about the structure of the lining of the colon. Is it ulcerated, etc.K.

I am an LG veteran..lol..probly 7 years or so. I've had a colonoscopy and a sigmoidoscopy and it showed nothing. I've had fairly comprehensive blood and urine tests done and they showed nothing.The most frustrating thing was, at the end of my first sigmoidoscopy (I changed GI docs and my new one insisted on performing one himself), the doctor goes, "There sure is alot of moisture down there. I'm guessing its sweat."And I was like "That's why I'm here!". And he gave me a blank stare.

Hi Smelly,I just had mine done and didn't expect to find an answer to my LG problem. I had the barium meal test done twice, years ago and they found nothing. This time they found diverticulous. Which didn't surprise me cause lots of people my age and even younger have it. I had mine done to make sure there was no sign of cancer. And to let my GP know that I followed his advice and had it done.I am not sure what my GI Doc told me to do about it, cause I could not understand his accent.
