Can dizziness be a sign of blood pressure fluctuations?

Question

Hello doctor,

Last year, my father had a heart attack, and it was treated successfully. However, a year later, he feels dizzy, weak, and has fluctuating blood pressure. Why is this happening?

Please help.

Hello,

Welcome to icliniq.com.

I would like to explain that dizziness could be a sign of blood pressure fluctuations. Other possible causes to consider include an inner ear disorder or reduced blood flow to the brain (vertebrobasilar insufficiency). For this reason, I recommend consulting his attending physician and conducting further tests. These may include a cardiac ultrasound to assess heart function, a Doppler ultrasound of the carotid and vertebral arteries to evaluate blood flow to the brain, tests for thyroid hormone levels, complete blood count to check for anemia, blood electrolytes, fasting glucose, and kidney and liver function. Additionally, a head-up tilt test may be necessary to investigate orthostatic hypotension.

Regards.
