Hello!

Thank you for asking on HCM!

I read your question and understand your concern.

I would like to explain that your symptoms are probably caused by the high blood pressure. You should know that the brain function is closely related to the blood pressure.

Normally within some blood pressure limits, the brain has an auto regulatory function, which allows it to maintain a normal function despite the slight fluctuations in blood pressure.

But if it is a higher blood pressure, the pressure is transmitted into the brain vessels and the brain tissue, causing dizziness, lightheaded feeling and headache.

I recommend consulting with your attending physician for a careful physical examination, a resting ECG, a routine blood test, kidney and liver function tests, blood electrolytes and thyroid hormone levels to exclude other causes of high blood pressure.

You should take into consideration beginning an anti hypertensive therapy to lower your blood pressure.

Hope to have been of help!

Best wishes,
Dr. Iliri
