Unfortunately, it can take upwards of 6 weeks for your body to adjust to not having a gall bladder anymore. The best thing you can do is eat blandly and avoid anything that's hard to digest, like raw vegetables and red meat. Oh, and try your best to avoid whatever foods were a bad trigger for you before you had your GB out. For me that was caffeine. For some it will be dairy or pizza or something else.
After 6 weeks, take stock of where you are, because that's pretty well how you're going to be from here on out. If you have diarrhea a lot, ask your G.I. for Welchol because it will bind up the bile in your stools. If you are constipated frequently try upping the amount of fat you eat daily (too little fat gave me SEVERE constipation--you need to eat fat to trigger your body to make bile) and if that doesn't help, ask your doctor about getting some bile salts. These replace the bile that your body isn't producing (as evidenced by the constipation). I don't think they are a prescription, but I know the pharamacy I went to looking for them when I was constipated (because of my low-fat diet) didn't carry them. I have seen them for sale online (how I heard about them). Your doctor should be able to tell you where to get them. Apparently they've been around for a really long time to treat constipation. May can find them in an herbal store.
My G.I.'s nurse told me that excess bile can go up or it can go down. When it goes down, you end up with bile diarrhea. When it goes up, you end up with acid reflux. Tell your doctor that you think your bile is going up and is there a prescription acid reflux medicine that will help you? (Bile going up isn't quite the same as stomach acid going up because your stomach isn't the problem in this case, so not all acid inhibitors will work--depends on how they work.)
14 weeks? Lucky!!! It took five or more doctors 5 YEARS to find my bad gall bladder! So you're talking to a woman with a LOT of experience with one! Lol. Not to mention I've had mine out 3 years now. I'm much better. Still can't have caffeine and have developed a problem with apples, but that's pretty much all I have to avoid. After you get straightened out, add your trigger foods back in one at a time and see how you react to them. Some you may be able to eat again and some you may not.
