Differential Diagnosis for Enteritis

The differential diagnosis for enteritis can be organized into the following categories:

  • Single Most Likely Diagnosis
    • Viral gastroenteritis: This is the most common cause of enteritis, often resulting from norovirus or rotavirus infection, and is usually self-limiting.
  • Other Likely Diagnoses
    • Bacterial gastroenteritis (e.g., Salmonella, Shigella, Campylobacter): These infections can cause enteritis and are often foodborne or waterborne.
    • Food poisoning: Similar to bacterial gastroenteritis, food poisoning can cause enteritis and is usually related to the consumption of contaminated food.
    • Inflammatory bowel disease (IBD): Conditions like Crohn's disease and ulcerative colitis can cause chronic enteritis.
  • Do Not Miss Diagnoses
    • Intussusception: A condition where a part of the intestine telescopes into another, which can cause bowel obstruction and ischemia if not promptly treated.
    • Appendicitis: Inflammation of the appendix, which can cause severe abdominal pain and may lead to perforation if not treated.
    • Mesenteric ischemia: A condition where the blood flow to the intestine is compromised, which can lead to tissue death and is a medical emergency.
  • Rare Diagnoses
    • Whipple's disease: A rare bacterial infection that can cause malabsorption and enteritis.
    • Eosinophilic gastroenteritis: A rare condition characterized by the infiltration of eosinophils into the gastrointestinal tract, which can cause enteritis.
    • Behçet's disease: A rare autoimmune disorder that can cause enteritis, among other symptoms.
    • Yersiniosis: A rare bacterial infection that can cause enteritis, often related to the consumption of contaminated food or water.
