Unexplained vomiting is directly related to acute gastroenteritis and pancreatitis attacks, which need to be treated for the disease. Acute gastroenteritis is usually caused by unclean diet or cold in the abdomen, and the disease can cause irritation to the patient’s intestinal mucosa, leading to digestive disorders. Not only does food accumulate in the stomach because it cannot be digested, but under the stimulation of inflammation, abnormal spasms occur in the stomach, squeezing the contents of the stomach, resulting in nausea and vomiting. Fatty foods can trigger the secretion of pancreatic fluid, and many people will suffer from the onset of pancreatitis due to the intake of large amounts of fatty foods. The onset of pancreatitis will not only affect the patient’s gastrointestinal system causing symptoms such as vomiting, but will also be accompanied by severe radiating pain. Acute pancreatitis attacks can lead to life-threatening failure of vital organs if not treated in time.
