Epigastric pain with nausea and vomiting, if the vomit is food residue without blood or coffee-colored liquid, may be acute gastritis, usually with slight relief of abdominal pain after vomiting, usually without fever and pain in the right upper abdomen and back. If the pain in the upper abdomen is in bouts and radiates to the back of the right shoulder, accompanied by nausea and vomiting, or a low fever, if it is caused by eating a greasy diet or overeating, the possibility of acute cholecystitis and gallstones should also be considered. This type of person can usually be known to have gallbladder stones during a physical examination. If acute epigastric pain occurs after drinking and binge eating, accompanied by nausea and vomiting and abdominal distention, the possibility of acute pancreatitis should also be considered, usually with pain in the upper abdomen and on the left side of the body, vomiting does not usually relieve, blood and urine amylase elevation, and CT ultrasound can further clarify the diagnosis. Abdominal pain is a complex disease with many causes, so it is recommended to go to the hospital to see a doctor to avoid delaying the condition.
