There is no specific value for how much high red blood cells are dangerous. The normal value of red blood cells is adult male (4~5.5) x 10^12/L and female (3.5~5.0) x 10^12/L. Red blood cell counts above the normal value may have the risk of increased blood viscosity, slowing down of blood flow, headache, and susceptibility to thrombus formation.
1. With a high red blood cell count, the blood will be in a viscous state, causing a serious burden on the cardiovascular system and predisposing to corresponding cardiovascular and metabolic diseases.
2. Excessive red blood cell count will slow down blood flow, affecting oxygen delivery and subsequently causing various pathologies.
3. Patients with erythrocytosis tend to suffer from headaches, which are caused by increased blood viscosity, impaired oxygen supply, and reduced oxygen supply to the brain.
4. High erythrocytes can also lead to the formation of blood clots. Due to the slowing down of blood flow, the increase in the number of erythrocytes and the change in the clotting function of platelets, people with high erythrocytes are more likely to form blood clots.
If you have high red blood cells, it is recommended that you go to the hospital in time to improve the examination and give targeted treatment or therapy.
