After gallbladder surgery, all types of foods are permitted, and no specific diet is recommended, according to the Mayo Clinic. However, fats should be taken in smaller quantities because their digestion is affected by the removal of the gallbladder. When the gallbladder is removed, less-concentrated bile constantly drains into the intestines, reducing the effective digestion of fat-soluble vitamins and fats.
When staying in the hospital to recover from gallbladder surgery, patients are helped with transitioning from a liquid diet back to solids, says Everyday Health. When recovering at home, patients should eat clear liquids such as broths and gelatin before slowly introducing solids.
Smaller amounts of fats are easier to digest after gallbladder removal surgery. Larger amounts of fats often cause diarrhea and bloating in people without gallbladders.
Patients should take small but frequent meals to ensure a good mix with the available bile. Lean protein such as nonfat dairy, fish and poultry should be added in small portions to every meal.
Foods with a high fat content, including fatty sauces and fried foods, should be avoided. Foods with a fat content of 3 grams or less are more suitable for these patients.
The fiber in the diet should be gradually increased. This helps minimize incidents of constipation and diarrhea by normalizing the bowel movements.
Though it depends on each individual, some patients find it more difficult to digest dairy products and caffeinated beverages. In such a case, these products should be avoided.
