I've had mine removed. It was done in 2004 and there are some side effects. For one you will be out of commission for at least a month working out. Secondly you'll have to alter your diet to restrict the amount of fatty foods you eat. The GB regulates the amount of stomach acid that is needed to help digest fatty foods. You will not be able to eat at a all you can eat barbarque place or eat a bucket of chicken without having major side effects. The main side effect is explosive diarrhia and stomach pain/indigestion. My main problem that I have is after eat a meal l have to go do a #2 soon afterwards without fail. I hate doing that in a public restroom but when you gotta go you gotta go. You also can't eat large meals and will have to snack all throughout the day instead. Your stomach will be outta wack for at least a couple of months afterwards too.
I hope the procedure goes well and just listen to your body because it will warn/tell you if there are problems.
I couldn't really tell you. I think mine has been fucked for YEARS but it's become VERY apparent now. Ever since I was a little boy i've had digestion problems. Now, I have a knot right below the last rib on my right side (where the gall bladder is). My stomach can no longer break down any kind of complex food. I've been reduced to salads, chicken, and simple vegi's lately. Anything else ***** up my stomach.
If you're having a heard time digesting food, passing your food, or any kind of pain from your intestinal areas you could have a damaged GB.
