Hi
Thanks for posting your query .
There are many causes for giddiness and
vomiting . From simple causes to serious causes .
If I was your doctor first I would have looked into all the simple causes first and if none found I would have investigated for serious causes.
Simple causes are : Low /
High BP , Low / High Blood Sugars , Low / High Blood sodium levels ,
Inner ear problems ,
Thyroid problems .
First get her BP checked , Blood sugar , Sodium ,
TSH Test done and an Examination by ENT doctor too . ( ask the doctor to do dix hallpike maneuver ).
Kindly revert back with the reports .
Any clarifications feel free to ask .
Happy to answer.
Regards
Dr.Divakara.P
