thank you for your query.
Your daughter is suffering from the flu.In children, gastrointestinal symptoms such as diarrhea
and abdominal pain
are common part of the flu.
I would advise her to get plenty of rest, drink plenty of liquids,avoid aspirin
as it can lead to Reye's syndrome.
is caused by a virus, antibiotics have no effect on the infection;and the infection generally subsides on its own in 3-4 days time
i would advise you to consult a doctor if the symptoms dont subside even after after 3 days of starting of the symptoms.as your daughter already has a metabolic condition.
wishing you good health
