Thirst in children
Informed by recognized medical guidance
Overview
Thirst in children is the feeling of needing to drink. It is normal after exercise, in hot weather, or after eating salty foods. But if a child is always very thirsty and drinking a lot, it could be a sign of an underlying condition, such as diabetes or dehydration.
Key facts
- Thirst is the body's way of telling you it needs more fluid.
- Excessive thirst (drinking too much) may be a sign of diabetes or other medical issues.
- Young children and babies cannot always tell you they are thirsty, so watch for signs like dry lips or few wet nappies.
Yes, occasional thirst is very common in children, especially during active play or warm weather. But persistent, excessive thirst is less common and should be checked by a doctor.
Thirst can affect any child, but babies, toddlers, and children who are very active or sick (with fever, vomiting, or diarrhoea) are more likely to become dehydrated and feel thirsty.
