When should you drink fluids when have the stomach flu?

It is generally recommended to drink plenty of fluids when you have the stomach flu.

Here are some guidelines:

- Drink fluids throughout the day, even if you don't feel thirsty.

- Clear fluids, such as water, broth, and electrolyte solutions, are best. Avoid sugary drinks, which can worsen diarrhea.

- Sip small amounts of fluids frequently rather than drinking a large amount at one time. This can help to prevent nausea and vomiting.

- Avoid alcohol, caffeine, and carbonated drinks, as these can also irritate the stomach and worsen symptoms.

- If you are vomiting frequently, you may need to seek medical attention as you may need intravenous fluids to prevent dehydration.
