HI
Greetings from Dr.Divakara.P
Thanks for posting your query.
There are many causes for
Dizziness, from simple and easily treatable causes to serious causes .
Simple causes are :
1. Abnormalities in BP: Both high and 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 )
5.
Inner Ear problems .
Some serious problems are :
1. Heart Problems
2: Brain problem
In your case , since you have a significant history of Brain disorder I would like to rule out Brain problems first before going for evaluation of other causes. So I recommend you to get MRI Brain and if it shows no new changes then go for the below advised test.
Get your Hemogobin , Serum Sodium levels, Serum TSH and Serum
Vitamin B12 levels checked and if they are normal get a ECG and a ENT check up done .
Hope this information is useful to you.
Any clarification feel free to ask.
