Stomach pain with vomiting is associated with food poisoning, acute gastritis, cholecystitis, and pancreatitis. Food poisoning can occur when some foods are consumed improperly or not handled cleanly. When food poisoning occurs, toxic substances will not only stimulate the mucous membrane of the stomach, but also damage the nervous system, so patients will not only experience pain in the stomach, but also nausea, vomiting and diarrhea. Acute gastritis can induce pain and nausea and vomiting due to factors such as congestion, edema and spasm and contraction of the gastric wall on the gastric mucosa during an attack, and attacks of cholecystitis are associated with cholestasis, infection and gallstone impaction. The pain of the gallbladder radiates to the surrounding organs during an attack, thus causing pain in the stomach. During an attack of cholecystitis, the excretion of bile is affected, which also leads to indigestion of food, thus causing vomiting, and during an attack of pancreatitis, the pancreatic gland digests itself, thus causing severe pain, and also causes pain in the stomach by involving the surrounding organs. The lack of pancreatic juice in the food causes indigestion, which can also lead to vomiting.
