I have lost about 10 lbs in 6 days while having stomach flu, which I still have. Is this normal?

In brief: Can happen

You can lose excess fluids through diarrhea and vomiting.
If you are taking in few calories - you may be burning up glycogen which is stored in the liver. That also holds fluid - so can lose more fluids that way. In addition - you may be burning some muscle and fat. Ensure that you hydrate well. If you can't keep up with fluid losses IV hydration may be needed.
