Gallbladder issues, specifically symptoms of cholecystitis, mainly include chills, fever, persistent dull pain in the upper right quadrant of the abdomen, episodic colic pain that radiates to the right shoulder and back, and may also be accompanied by jaundice, dark urine, nausea, vomiting, and constipation. Patients with cholecystitis often experience sudden pain at night, typically due to overeating or consuming greasy foods. Once cholecystitis occurs, it is advised to seek medical attention at a regular hospital as soon as possible, complete the relevant diagnostic tests, such as imaging studies of the abdomen, consider surgical treatment, and engage in active anti-infection treatment.
