What causes sudden dizziness?

My sister was driving to work this morning and suddenly had the sensation that her car was lifted on one side and it was sliding although it wasn t and her vision was fine. It stopped and shortly after her internal body felt like it was spinning but her vision was fine (what she looked at was not visually spinning). Then when she would stand she felt flushed. She also said for about 2 hours after she had to pee a lot and very often. What could this be?

Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.

One possibility for dizziness would be anemia, which commonly manifests with dizziness and tiredness. Heart rhythm and function abnormalities would also lead to insufficient blood supply to the brain and other organs so would also justify those symptoms. Another possibility would be metabolic alterations, like diabetes, altered kidney or liver function, electrolyte abnormalities. Hormonal causes like thyroid dysfunction or nutritional ones like vitamin B12 deficiencies must be considered as well. If the symptoms have appeared only very recently it might be a simple transitory viral infection which are generally transitory and need only rest and hydration. The list can go on for long, as I said those symptoms can be found in numerous conditions, only listed some of the most common ones. So I would start evaluation with some routine cheap tests to screen for anemia, infections and metabolic issues like complete blood count, erythrocyte sedimentation rate, glucose, liver and kidney function, electrolyte panel, thyroid function, vitamin B12 levels, EKG.

Hope I have answered your query.
