Acute gastritis and nausea and vomiting

Acute gastritis is often caused by something that irritates the lining of the stomach. Examples include:

  • Infections: Infections are often the cause of stomach irritation, whether it is a common virus or another type of infection. There may be associated crampy upper abdominal pain that is associated with the nausea and vomiting. Fever ,and chills may be present. Common viral infections include noroviruses and rotavirus. Infection by bacteria in the Helicobacter family (such as H. Pylori) can also be the infectious agent.
  • Stomach flu: Stomach flu (gastroenteritis) is when vomiting and diarrhea occur together and is associated with a viral infection. It should not be confused with influenza (symptoms include fever, chills, cough, and muscle pain.
  • Food poisoning: Food poisoning may cause significant vomiting, and the most common cause is a toxin released by the bacteria Staphylococcus aureus.  Symptoms of food poisoning begin within a couple hours of eating contaminated or poorly prepared food. Other bacterial causes of food poisoning include Salmonella, Campylobacter, Shigella, E. coli, Listeria, or Clostridium botulinum (botulism).
  • Other stomach irritants: alcohol, smoking, and nonsteroidal anti-inflammatory medications (NSAIDs) such as aspirin and ibuprofen may irritate the stomach lining and cause nausea and vomiting.
  • Peptic ulcer disease: Peptic ulcer disease can range from mild irritation of the stomach lining to the formation of a defect in the protective lining of the stomach called an ulcer.
  • Gastroesophageal reflux disease (GERD, reflux esophagitis): Nausea or vomiting is also associated with GERD (acid from the stomach is refluxed into the esophagus).
