Hello doctor, Last year my father had a heart attack and well it has been treated well. But after a year he feels his head to be spinning, weak, and has fluctuating blood pressure. Why is it so?
Hello. I would like to explain that the head spinning could be a sign of blood pressure fluctuations. Other possible causes to consider would be an inner ear disorder or low blood flow to the brain (vertebro-basilar insufficiency). For this reason, I would recommend consulting with his attending physician and performing some further tests. A cardiac ultrasound to examine his heart function, a Doppler ultrasound of the carotid and vertebral arteries to examine the blood flow to the brain, thyroid hormone levels, complete blood count for anemia, blood electrolytes, fasting glucose, kidney, and liver function tests. A head-up tilt test is necessary to investigate for orthostatic hypotension.
