What Causes Dizziness Despite A Normal CBC Report?

default
Posted on Tue, 25 Oct 2016
Question: For the past 7 months I get this weird feeling that either everything is moving or like I am fading in and out as if I am about to faint.

So far my doctor has order full CBC panel everything is normal. MRI of the brain normal. Ultrasound of both right and left carodit, normal. EKG normal. She has refereed me to a cardiologist.

What can be causing these chronic episodes. What can I do to make them go away or minimize them. In all honesty I don't remember the last time I didn't feel like this, this is starting to interfere with my personal life.

Please advise.

I am a 38 year old female no medical conditions. 5'8 weight 120

Detailed Answer:
Hello!

Thank you for asking on HCM!

Regarding your concern, I would explain that it is important to differentiate between the possible causes that may lead to this clinical scenario:

- a cardiac arrhythmia
- an inner ear disorder
- thyroid dysfunction
- epilepsy seizures

Carotid stenosis, possible intracranial lesions have been excluded by your performed tests


So I would recommend performing further tests to investigate for the possible causes:

- a cardiac ultrasound to examine your heart function and structure
- an ambulatory 24-48 hours ECG monitoring to investigate for possible arrhythmia
- thyroid hormone levels
- an EEG to exclude possible seizures

Consulting with an ENT specialist and performing labyrinthine tests is also necessary to exclude an inner ear disorder.

You should discuss with your doctor on the above mentioned issues.

Kind regards,

Dr. Iliri

Hello

My thyroid levels are normal and the EEG test was also normal. I have an apt today with a cardiologist, I will ask them about the exams listed about and I will ask my primary doctor for an ENT referral.

What about the faint spells what can I do about them? As in medication.

And which possible arrthymias can be causing this??

Please advise.

thank you

Detailed Answer:
Hello again!

Thank you for the additional information!

Regarding your concern, I would explain that the episodes of fainting could be related to every type of cardiac arrhythmia.

You should know that during short episodes of cardiac arrhythmia, the heart is not able to pump the blood properly and the brain is the first organ to feel low blood perfusion and reacts with similar symptoms like dizziness, lightheadedness, blurring vision and even fainting.

A cardiac ultrasound and an ambulatory 24-48 hours ECG monitoring will help rule in/out any cardiac problem related to this symptomatology.

I would also recommend consulting with an ENT specialist and performing labyrinthine tests to exclude a possible inner ear disorder, which could mimic this symptomatology.

Hope to have been helpful!

Greetings,

Dr. Iliri
