Well, other than the obvious dietary risks such as high blood pressure, high cholesterol and weight gain, not having a gallbladder can cause you to have diarrhea after eating, especially if the food is high in fat.
Are you having "bowel dumps"? I had my GB removed in 2009 and if I ate any fast food or greasy food I would almost immediately be in the bathroom and the gas and cramps are awful! This lasted roughly 8 months for me! Give your insides time to heal. It has been 2 years for me and I still occasionally have this issue. I also noticed if I do not eat when I am hungry and wait too long I have this issue regardless of what I consume. To keep you digestive system operating smoothly eat light,
healthy and small portions of food.
Even with a Gallbladder people should try to eat healthier. I don't believe you are going to have a horrible outcome just because you are eating wrong, but you might have loose stools as a result. You won't have the same symptoms because you don't have any stones in your common bile duct to block the flow of bile..also you don't have an imflammed gall bladder
