Hello,

The following are few causes of dizziness and nausea:
1) Severe hypoglycemia or lowered blood sugars
2) Severe hypotension or lowered blood pressure
3) Myocardial infarction or heart attack
4) Cardiac arrhythmia
5) Angina

She needs to be clinically examined in person and undergo the following tests:
1) ECG
2) Blood pressure measurement
3) Blood glucose levels
4) 2D echo radiography

Please do consult a physician or a cardiologist for further evaluation.

Take care. Hope I have answered your question. Let me know if I can assist you further.

Regards,
