Differential Diagnosis for Patient with Diarrhea, Sore Throat, and Dizziness

Single Most Likely Diagnosis

  • Viral Gastroenteritis: This is the most likely diagnosis given the combination of diarrhea, sore throat, and dizziness. Viral gastroenteritis, often caused by norovirus or rotavirus, can lead to these symptoms, along with possible fever and vomiting. The sore throat could be a concurrent viral pharyngitis or part of the systemic viral infection.

Other Likely Diagnoses

  • Food Poisoning: This could cause diarrhea and potentially sore throat if the food poisoning is due to a bacterial or viral agent that also affects the throat. Dizziness could result from dehydration or the toxin effects.
  • Influenza: Although primarily known for causing respiratory symptoms, influenza can also lead to gastrointestinal symptoms like diarrhea in some cases. Sore throat and dizziness (from fever or dehydration) are also possible.
  • Mononucleosis (Mono): Caused by Epstein-Barr virus, mono can present with sore throat, fever, and sometimes gastrointestinal symptoms. Dizziness could be due to fever or dehydration.

Do Not Miss Diagnoses

  • Meningitis: Although less likely, meningitis is a critical diagnosis that must not be missed. Early symptoms can be non-specific, including fever, sore throat, and dizziness. Diarrhea is not a typical symptom but could occur in the context of systemic infection.
  • Septicemia: Bacterial sepsis can cause a wide range of symptoms, including diarrhea, sore throat, and dizziness, especially if the causative organism affects multiple systems or if the patient is immunocompromised.
  • Botulism: This rare but serious illness can cause dizziness, among other neurological symptoms, and sometimes gastrointestinal symptoms like diarrhea. A sore throat could be part of the initial symptoms.

Rare Diagnoses

  • Ciguatera Fish Poisoning: This rare condition, caused by eating contaminated fish, can lead to gastrointestinal symptoms like diarrhea, neurological symptoms like dizziness, and sometimes a sore throat.
  • Brucellosis: A zoonotic infection that can cause a wide range of symptoms, including fever, sore throat, and gastrointestinal symptoms. It's rare but could be considered in individuals with exposure to animals or contaminated animal products.
