Cholera is an acute infectious disease caused by Vibrio cholerae. Its clinical course varies from mild diarrhea to severe complications with hypokalemia, hyponatremia or hypernatremia, hypocalcemia, metabolic acidosis, and acute kidney injury. This is a case of a 20-year-old Asian man with recent travel history from Bangladesh who presented to the emergency department with abdominal pain and multiple episodes of watery diarrhea. He developed acute renal failure secondary to severe gastroenteritis, the cause of which was later confirmed to be cholera.
