Fasting on water during a gallstone attack can reduce bile production and relieve symptoms.
Bile is secreted by the liver and then emptied into the gallbladder, which concentrates and stores the bile again, when the patient is in a fasting state bile is stored in the gallbladder. When the patient is fasting, the bile is stored in the gallbladder. After eating, the gallbladder contracts and discharges the bile into the intestinal lumen to help digest food.
During an attack of gallstones, the patient can experience spasmodic contractions of the gallbladder, colic in the upper abdomen, nausea, and vomiting. If the patient eats again, it can irritate the gallbladder and aggravate the symptoms. Therefore, fasting and water fasting is needed during gallstone attacks to reduce bile secretion and irritation of the gallbladder, and to help patients recover from their condition.
In the process of fasting and water fasting, patients must follow the doctor’s instructions, not to ingest food and water privately, so as not to aggravate the condition.
