Cholera often begins suddenly with profuse, watery diarrhea that looks like “rice-water,” followed by vomiting, rapid dehydration, dry mouth, sunken eyes, muscle cramps, and weakness. If untreated, patients can develop low blood pressure, rapid heartbeat, confusion, or shock within hours—these are signs needing immediate medical care. Unlike other diarrheal diseases, cholera typically does not cause fever or abdominal pain, and the fluid loss is much more rapid and severe. The sheer volume of watery stools and quick onset of dehydration help distinguish cholera from common foodborne or viral diarrheas. Seeking prompt medical attention is vital, as early rehydration can prevent death and ensure full recovery.
