Intrahepatic bile duct stones are a type of gallstone disease, the main component of which is bile pigment stones, so the diet for intrahepatic bile duct stones is the same as that for gallbladder stones and extrahepatic bile duct stones. First of all, we should pay attention to regular diet, avoid overeating and drinking alcohol. Secondly, a light, easy-to-digest diet should be the main focus. You can eat more fruits, vegetables, lean meat, fish, soy products, such as celery, rape, spinach, cabbage, beef, chicken and so on. Avoid eating fatty and oily foods, such as fatty meat, animal offal and squid, etc. You should also avoid eating fried fast food, such as chicken tenders, burgers and pizza. However, the formation of intrahepatic bile duct stones is related to the anatomical abnormalities of the bile duct, and intrahepatic bile duct stones with clinical symptoms should be treated promptly.
