Enteritis
Enteritis is inflammation of the small intestine. It is most commonly caused by food or drink contaminated with pathogenic microbes, such as Serratia, but may have other causes such as NSAIDs, radiation therapy as well as autoimmune conditions like Crohn's disease and celiac disease. Symptoms include abdominal pain, cramping, diarrhea, dehydration, and fever. Related diseases of the gastrointestinal system (including gastritis, gastroenteritis, colitis, and enterocolitis) involve inflammation of the stomach and large intestine.
