Patient's question:
Originally, Dad was going to donate blood for free today, but he cannot donate blood for free because of high blood pressure. Why can high blood pressure prevent blood donation?Doctor's answer:
If you have high blood pressure, you should actively control your blood pressure. Lowering your blood pressure to a normal level should allow you to donate blood for free. If your blood pressure is already unstable, donating blood could potentially cause significant fluctuations in your blood pressure, leading to a recurrence of cardiovascular and cerebrovascular diseases. This would be counterproductive. Therefore, when donating blood, there will be certain recommendations to help prevent any unexpected incidents.
