The foods that gallstones are most afraid of are foods that are too oily and heavy. For example, fatty meat, fried eggs, or very oily soups, such as chicken soup or pork ribs soup. Because the patient eats overly oily food, mainly fried eggs, with more fat and more protein, the patient may have gallbladder contraction and abnormal gallbladder contraction, which may lead to biliary colic attacks. Patients will have very severe abdominal pain, usually mainly subxiphoid pain, and may also have right upper abdominal pain. After the onset of biliary colic, the patient may develop acute inflammation of the gallbladder secondary to inflammatory changes in the gallbladder. Patients may develop fever, nausea and vomiting, or transient jaundice.
