I can understand your concern.
A lot of causes like hypotension, hypoglycemia, ENT disorders, anemia can cause dizziness and vertigo.
More history on the vertigo is required. Does it feel like she is spinning or the objects in the surrounding spinning.
I suggest you consult a general physician first and get a complete blood counts done.
Next Consult a ENT SPECIALIST to rule out ENT causes of vertigo.
Drink lots of water. Have lots of greens and fruits.
Having a high protein powder
