Cholera and rice water

Cholera can drain water and electrolytes from the body rapidly. Rice water is a food-based drink, so its composition can vary with how it is prepared and it may not contain the balance needed for effective rehydration. It also does not remove the cause of the infection. Someone may feel temporarily less thirsty while dehydration continues, particularly if stools remain frequent.

Track the illness rather than judging it by thirst alone. Changes in [Diarrhoea](/symptoms/diarrhoea/) pattern, urine output, alertness and ability to drink are useful details for a clinician.

Use prepared [Oral Rehydration Therapy](/treatments/acute-and-urgent-care/oral-rehydration-therapy/) as the main drink for fluid replacement, following the packet instructions and using safe water. Give small, repeated sips if vomiting occurs. Rice water can be offered as an additional drink or food only if the person can tolerate it; do not let it delay professional care. Marked dehydration may require [IV Fluid Therapy](/treatments/acute-and-urgent-care/iv-fluid-therapy/) in a healthcare setting.

Seek urgent care for confusion, fainting, unusual sleepiness, very little urine, a racing heartbeat, cold or clammy skin, persistent vomiting, or an inability to keep fluids down. Infants, older adults and people with chronic illness can deteriorate quickly. Frequent watery diarrhoea itself is a reason to contact a healthcare service, especially when the person cannot replace each loss by drinking.

Ask whether rice water is suitable alongside oral rehydration solution, how to prepare and give the recommended solution, which signs show worsening dehydration, and when intravenous treatment is needed.
