Cholecystitis may cause abdominal pain, nausea and vomiting, anorexia and other symptoms, and some patients may have symptoms aggravated after eating. 1. Abdominal pain: the cause of cholecystitis is relatively clear, and it is considered to be caused by obstruction of the gallbladder duct, gallstones, bacterial parasite infection and other factors. If you don’t pay attention to your diet, overeating, consuming more greasy, spicy and stimulating, high-fat food, or being addicted to alcohol, it may lead to an attack of acute cholecystitis, which will cause obvious abdominal pain. 2. Nausea and vomiting: If the patient often overeats, food intake leads to increased pressure in the gastrointestinal tract, which can cause reflex nausea and vomiting, and the vomit contains a certain amount of bile. Cholecystitis patients with sudden right upper abdominal pain or knife-like pain, intermittent colic, nausea and vomiting and other manifestations, it is recommended to promptly go to the gastroenterology department of the hospital to avoid delays in the condition.
