hi. thanks for posting query at HCM. The cause of diarrhea after gallbladder removal is not certain. Some experts believe that it results from an increase in bile, especially bile acids which may act as laxative in the large intestine. it should subside soon, usually lasts from few days to few months. advise: - Avoid high-fat foods, fried and greasy foods - Add soluble fiber, such as oats and barley, to your diet. But be sure to increase the amount of fiber slowly, such as over several weeks, because too much fiber at first can make gas and cramping worse. - Eat smaller, more-frequent meals. - avoid caffeine and dairy products wish her good n sound health regards Dr Tayyab Malik
