Patient's question:
Here is the translation of the provided text into English:"They say that donating blood regularly without payment is beneficial for health. So, I would like to ask, can people with high blood pressure donate blood without payment?"
Doctor's answer:
If you have high blood pressure, you cannot donate blood for free. The cause of voluntary blood donation requires a healthy body. If you have high blood pressure and need to take oral medication long-term, you are especially prohibited from donating blood during the medication period. If you have high blood pressure, you also cannot donate blood. These are contraindications. If you need to recruit personnel, you must clearly state your physical condition to prevent other accidents.
