Dehydration
When your body fights again the virus and bacteria that are causing stomach flu, it is likely to suffer from dehydration as a side effect. This often happens because the body might lose a lot of fluids when it is trying to get rid of the harmful elements from inside. For instance, you can lose water due to diarrhea, sweat, or urination. As a result, it will lead to many other health issues such as fatigue, dry skin, red eyes, or dizziness. [9]
