<s>[INST] my wife had her gallbladder removed about three weeks ago.  From day one after the surgery she has experienced diahreha and vomiting after any food or liquid. And I mean ANY.  We even tried the vitamin K shakes and similar shakes to help replace nutrients lost from vomiting. She has lost about 20lbs since the surgery from lack of eating.  And the vomiting is immediate after eating not hours like I have read from most peoples posts about post surgery complications.  During her scans before the surgery everything came out good, they even had to do two scans before they determined her gallbladder was bad. There were no stones found, just was told that her gallbladder was functioning at about 15% so they recommended removing it.  I understand that there are going to be post op problems but shouldnt she be able to eat or drink something without vomiting or diaherrea?  should they atleast given her something to stop her from throwing up? [/INST] Hi thanks for your question. Loose stool along with indigestion is problem after cholecystectomy that is removal of gallbladder. But this problem get settle down in few weeks as Hillary system get adopted and release bile when there is food in stomach. Function of gall bladder is to store and concentrate bile juice which contains bile salt for absorption of fat. Fat is not absorbed without emulsification. This function of gall bladder is taken by Billy system, and it takes few weeks to do so. During this period patient can have indigestion, loose stool and very rarely omitting due to bile induced gastritis. But since there were no stone in gall bladder and cholecystectomy was done for non-functional gallbladder, other reason for omitting and diarrhea has to be ruled out. Weight loss is due to omitting and diarrhea. Re Consult her operating surgeon who may have a second look to determine the cause of her problems. Treatment will depend upon cause. Hope this answers your question </s>
