Gallbladder pain is usually a sign of cholecystitis, which can be categorized into acute cholecystitis and chronic cholecystitis. 1. Acute cholecystitis: (1) Acute calculous cholecystitis: this kind of cholecystitis is often due to stones blocking the gallbladder duct, or due to the presence of stones leading to the retrograde entry of disease-causing bacteria from the bile duct into the gallbladder, which triggers acute inflammation, and the patient may initially experience discomfort in the gallbladder area, and then experience severe pain. (2) Acute non-calculous cholecystitis: patients are often secondary to severe burns and other traumatic injuries, but also may be AIDS, long-term parenteral nutrition complications, patients may also experience pain in the gallbladder. 2. Chronic cholecystitis: most patients have gallbladder stones, when the patient’s gallbladder stones repeated attacks, the bile duct repeated obstruction, which can lead to the symptoms of gallbladder pain. When gallbladder pain occurs, the patient should consult a doctor in time for abdominal ultrasound and other tests to make a clear diagnosis, and then standardize the treatment to avoid delaying the condition.
