If the gallbladder is removed, bilirubin levels will normally return to normal within a few months. However, a "special" diet must be followed after gallbladder removal. Following a diet low in animal fat and high in fiber, with plenty of fruits and vegetables and also all types of nuts can help lessen the need for gallbladder removal. Thals will see higher levels of bilirubin, but unless it is causing painful gallstones, it's not any danger.
