It is generally not recommended for hypertensive patients to donate blood, and blood donation does not have any benefits for hypertensive patients. Blood donation generally refers to non-remunerated blood donation, where healthy adults who meet certain physical requirements provide their own blood to blood collection and supply organizations in order to help patients who need life-saving blood transfusions due to various reasons. Blood donation requires an individual’s age, weight, blood pressure, pulse rate, etc. Hypertensive patients are among those who cannot donate blood. Even if hypertensive patients can donate blood, the disadvantages outweigh the benefits. Donating blood will cause the patient’s blood volume to drop, thus causing fluctuations in blood pressure. If the patient also suffers from coronary heart disease, the drop in blood volume after blood donation may also lead to ischemia in the narrowed lumen of the coronary artery, and in severe cases, myocardial infarction may even occur. Therefore, it is not recommended for hypertensive patients to donate blood. Hypertensive patients should follow the doctor’s instructions to adjust their lifestyles and regularly monitor the changes in blood pressure.
