Dear Sir, This is Kiran from Hyderbad. My father has undergone bypass surgery 7months back and he is recovered. since 2days he is experiencing slight dizzyness. Could you please let us know what would be the cause for this. Do we need to consult a doctor immediately? Please help us. my email id is YYYY@YYYY Thanks & Regards, Kiran
Hello, I understand your concern and would explain that the dizziness does not seem to be related to the bypass surgery.  Coming to this point, I would recommend you to closely monitor his blood pressure values for possible fluctuations and perform a Doppler ultrasound of the carotid and vertebral arteries in order to check for possible narrowing and low blood flow to the brain.  If the Doppler results normal, I would recommend performing a cervical spine X-ray study for possible chronic degeneration and consulting with an ENT specialist.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
