Thanks for posting your query.
There are many causes for

Simple causes are :

low BP can cause dizziness.
2. Abnormalities in Blood sugars: Both high and low Blood sugars can cause dizziness.
3. Abnormalities in blood sodium levels.
4. Low
Hemoglobin (
Anemia )

Inner Ear problems .

In your grandmother's case ,low BP is one possible cause of Dizziness . So kindly get her more fluids and increase her salt intake . Also check her blood sugars in fasting and after her breakfast ( 2 hours ) and meals .
Also get her Hemogobin , Serum Sodium levels checked and if they are normal get a ECG and a ENT check up done .
Hope you find this information useful .
