winter is a high incidence of cardiovascular disease, especially in patients with hypertension, with blood pressure fluctuations, and a wave of rumors began to spread.
, how much have you heard?
ancestral old Chinese medicine bloodletting therapy.
high blood pressure is too much blood, put some of the blood out, blood pressure naturally down.
blood donation can lower blood pressure.
anemia will not get high blood pressure.

when it feels that the blood volume is reduced, it is contracted to narrow the lumen to compensate for the loss of blood volume. Only when a large number of blood loss is more than its ability to shrink, there will be a decline in blood pressure.
