The Stomach Virus and Dehydration

Dehydration is one of the biggest dangers for anyone with a stomach virus. Someone who has stomach flu loses a lot of fluids--often very quickly - through vomiting and diarrhea. Dehydration results in the loss of certain salts and minerals that the body needs to function.

Symptoms of dehydration include

• decreased tears
• dizziness or lightheadedness
• dry mouth
• excessive thirst
• little or no urine or dark yellow urine
• severe weakness or lethargy

A minor case of dehydration can be treated by simply drinking liquids. But in cases of severe dehydration, intravenous fluids and hospitalization may be necessary. Extreme dehydration can be life threatening.

Dehydration from stomach flu is especially dangerous for children because their bodies are smaller. It's best to keep a minimum supply of oral rehydration solutions (also known as ORS) in the home. Pedialyte, for instance, can help replace lost fluids. It includes the electrolytes and salts the body needs to function.

A prescription isn't needed and ORS can be found at most pharmacies. Be sure to use clean or boiled water, and to follow directions carefully. Follow the written directions on the ORS package, and use clean or boiled water.

In severe case of dehydration from stomach flu, intravenous liquids may be necessary.

To stay properly hydrated during a bout of stomach flu, take small sips of water or other clear liquids.
