Polycythemia is a disease which causes an excessive number of red blood cells to be produced. The disease is the result of a faulty gene. How would the flow of blood be affected by this condition?

The blood flow would be delayed, since the amount of red blood cells increases the total density of blood volume, which is why the greater the quantity of blood, the thicker the blood will be.

This, as a consequence, could cause thickening of the blood, thus becoming denser, affecting the continuous laminar flow inside the blood vessels, this means that the flow is not unidirectional, but when it is delayed, it produces a kind of micro whirlpools that hinder healing, circulation, oxygenation and stimulate the appearance of deep and superficial clots or thrombosis.

Explanation:

It is important to clarify that the polycythemia which we are talking about is very excessive, very noticeable, unlike the physiological polycythemia that the body does when faced with an increase in height and a decrease in partial pressure of oxygen.

This is important for you to know, because the body when we climb a mountain or climb, or the partial pressures of oxygen decrease in the atmosphere, takes as a compensation mechanism the increase of red blood cells to maintain the oxygenation of the body, but this being PHYSIOLOGICAL is not excessive.

Polycythemia due to genetic failure such as the one we are writing now is a pathology because we are facing an excessive EXCESS of red blood cells, where phenomena of jaundice and hemolysis can also occur due to the great imbalance that is generated in the entire body
