Dehydration is when there is not enough water in the body.
Dehydration in teens usually is caused by vomiting, diarrhea, or both. It also can happen if a sore throat makes it hard for someone to drink enough. Teens also can get dehydrated in hot weather or when they are very active.
Signs of dehydration include:
Most teens with dehydration can be treated at home. To help with dehydration:
Call your doctor if you:
Call 911 or have someone take you to the ER if you are having trouble staying awake.
Whenever you get sick, try to drink extra liquids.
In very hot weather or when you do heavy exercise, you need to drink more than usual. Drink extra water before you go outside in hot weather, play sports, or plan to be very physically active. Then, take regular drink breaks (about every 20 minutes) during the activity.
Drinking water before, during, and after playing sports is enough to keep most teens hydrated. Some athletes who exercise for long periods or in very hot weather can benefit from a sports drink that has sugar and electrolytes. Ask your doctor or coach if they think you need to drink sports drinks.
