Differential Diagnosis for Vomiting and Diarrhea with Brownish-Colored Vomit

  • Single Most Likely Diagnosis
    • Gastroenteritis: This is the most likely diagnosis due to the combination of vomiting and diarrhea, which are common symptoms of gastrointestinal infections. The brownish color of the vomit may indicate the presence of bile or blood, which can be seen in more severe cases of gastroenteritis.
  • Other Likely Diagnoses
    • Food Poisoning: Food poisoning can cause vomiting and diarrhea, and the brownish color of the vomit may be due to the ingestion of contaminated food or drinks.
    • Viral Gastroenteritis (e.g., Norovirus): Norovirus is a common cause of viral gastroenteritis, which can lead to vomiting and diarrhea.
    • Inflammatory Bowel Disease (e.g., Crohn's disease, Ulcerative Colitis): Although less common, inflammatory bowel disease can cause chronic diarrhea and vomiting, and the brownish color of the vomit may indicate blood or bile in the stool.
  • Do Not Miss Diagnoses
    • Intestinal Obstruction: Although less likely, intestinal obstruction can cause vomiting and diarrhea, and the brownish color of the vomit may indicate bile or blood. This diagnosis is critical to rule out, as intestinal obstruction can lead to severe complications if not treated promptly.
    • Appendicitis: Appendicitis can cause vomiting and diarrhea, and the brownish color of the vomit may indicate bile or blood. This diagnosis is important to consider, as appendicitis can lead to severe complications if not treated promptly.
    • Mesenteric Ischemia: Mesenteric ischemia is a rare but life-threatening condition that can cause vomiting and diarrhea, and the brownish color of the vomit may indicate blood or bile.
  • Rare Diagnoses
    • Intussusception: Intussusception is a rare condition where a part of the intestine telescopes into another part, causing vomiting and diarrhea.
    • Eosinophilic Gastroenteritis: This is a rare condition characterized by inflammation of the gastrointestinal tract, which can cause vomiting and diarrhea.
    • Whipple's Disease: Whipple's disease is a rare bacterial infection that can cause diarrhea, vomiting, and weight loss.
