The early symptoms of cholecystitis are distinguished as chronic cholecystitis or acute cholecystitis. Chronic cholecystitis is mainly based on digestive symptoms, while acute cholecystitis is mainly based on abdominal pain symptoms.

The early symptoms are mild and may only be epigastric stuffiness and discomfort after overeating or eating fatty foods, the degree of which varies from person to person. In the later stages, if no effective intervention, the symptoms tend to worsen, manifesting as nausea, aversion to oil, belching, weakness, or even vomiting in more serious cases. Second, acute cholecystitis 1, abdominal pain: early symptoms are mainly abdominal pain, the beginning of only the upper abdominal distension and discomfort, part of the aggravation later will be manifested as paroxysmal colic, depending mainly on individual differences in the condition. The pain may also be radiated to the right shoulder and scapula of the back in the early stage, the pain is relatively mild in the early stage, and also accompanied by the symptoms of abdominal distension; 2, indigestion: most of the acute cholecystitis attacks will also be combined with indigestion, mainly nausea, aversion to oil, weakness, tiredness, etc.; 3, high fever: a small number of acute cholecystitis did not appear at the beginning of the symptoms of abdominal pain, but directly manifested as a chill, chills, and then appear high fever, temperature significantly. After that, high fever and markedly elevated body temperature appear, which is a systemic inflammatory reaction caused by serious bacterial infection and can cause infectious shock in severe cases, while the abdominal signs are not particularly typical; 4. jaundice: a very small proportion of acute cholecystitis is manifested by jaundice in the early stage, with yellow eyes, yellow urine, yellow skin, white and light stools, mainly because of stones embedded in the common bile duct, or in the gallbladder This is mainly due to the combination of stones embedded in the common bile duct or in the common hepatic duct caused by Mirizzi’s syndrome due to compression of the stones in the duct.
