Every once in awhile, I eat something, and it's out of my system in less than an hour by diarrhea. Yesterday, it was a shrimp ceviche (no crackers & it wasn't that citric) that did it to me. I wonder how many calories are absorbed when that happens? Anyone have similar experiences or know???

I have this problem due to my gall bladder, there are certain foods that get me, and other times it is a fluke. Because of how quickly it is leaving your system there is probably going to be a lack of calories/nutrients that are absorbed, but if it is happening infrequently it shouldn't pose a problem. You may want to keep track in a journal of the item you ate, and the components. So if you had shrimp ceviche, write down everything you put it in and then if it 2 weeks it happens again and there was one common ingredient you may want to try to avoid it.

When I was having gallbladder issues, I couldn't eat pizza without running to the bathroom within about half an hour.. when I did, ****TMI ALERT*** the toilet would have oil just floating on top of the Water. Same with Chinese food. I'd NEVER leave the restaurant until I had gone to the bathroom because I had to GO within minutes of finishing my meal and it was EXPLOSIVE.. and again grease just floating there.

Oddly, I could eat pastries with no trouble.. and we all know pastries are full of fat, so I don't know why the fat in chinese food and pizza was different in my body?!

Thank you for your posts.... Makes sense w the gall bladder... I had mine removed over 10 years ago...I will keep track & see if there is a pattern! Thanks!

When did you have your procedure? How much weight have you lost so far? I wish I had this info to give you better feedbacki....Thanks.

Surgery was 11/5/12 & have lost 72lbs. Still have 60lbs to hit my goal

Any dairy products in what is causing you problems?? Some people become lactose intolerant after surgery. Just the opposite for me so far....but I also had problems with certain raw vegetables and lettuce. Not tried those since surgery.

Some people mistake what is causing them to run to the bathroom, with small incremental meals this can be the case easily.

One thing...if you can look at it, and go "that's a piece of" or "thats the", then that may be a part of the issue. We really need to chew our food thoroughly from now on, for the small particulates but also for the saliva that mixes with it - one reason never touched upon about "the no drinking with meals" rule is that when we drink with our meals, we rely less on saliva, which makes the tummy work harder. Think of your saliva as a pre-digestive venom would be in spiders...

Rapid dumping if it persists (i have been told and read, but not really experienced) is a serious issue, as it puts stress on your colon the way acid reflux does to your throat. Your colon is 30 ft long, if your bowels are moving rapidly enough to pass anything through that in an hour, it should be looked into.
