What is the triad of acute cholecystitis?

　　The triad of acute cholecystitis refers to right upper quadrant abdominal pain, nausea and vomiting, and fever. These three symptoms often occur simultaneously or sequentially and serve as important clinical criteria for diagnosing acute cholecystitis. Some patients may also present with additional manifestations such as jaundice or abdominal distension. If these three symptoms appear, prompt medical evaluation at a hepatobiliary surgery clinic or emergency department is recommended.

　　1. Right upper quadrant abdominal pain: Typically sudden-onset, persistent dull or colicky pain that may radiate to the right shoulder or back. Pain usually worsens after consuming fatty foods and intensifies upon palpation of the gallbladder area in the right upper abdomen. This is a classic symptom caused by inflammation of the gallbladder irritating surrounding tissues.

　　2. Nausea and vomiting: Commonly accompany abdominal pain. Vomit typically consists of gastric contents. In some patients, abdominal pain may temporarily subside after vomiting. Frequent vomiting or vomiting of bile may indicate more severe gallbladder inflammation affecting normal gastrointestinal motility and emptying.

　　3. Fever: Most patients develop moderate fever, with body temperature generally ranging between 38°C and 39°C. If complicated by biliary tract infection or suppurative cholecystitis, the temperature may rise above 39°C, possibly accompanied by chills. Fever represents the body's normal inflammatory response and also reflects the severity of the condition.

　　In daily life, maintain a low-fat diet, avoid overeating, eat meals regularly to reduce gallbladder burden, keep the abdomen warm to prevent cold exposure, rest appropriately after meals, avoid strenuous activity, maintain emotional stability, and minimize factors that may trigger inflammation.
