What is the reason for low reduced viscosity of whole blood

Low whole blood reduced viscosity may be related to factors such as anemia, blood dilution, and enhanced red blood cell deformability. Whole blood reduced viscosity is an important indicator reflecting blood fluidity, and when it is low, it needs to be comprehensively judged in conjunction with other examination results. Anemia is a common cause of low whole blood reduced viscosity. When the hemoglobin content decreases, the number of red blood cells in the blood decreases, and the viscosity of the blood decreases accordingly. Iron deficiency anemia, megaloblastic anemia, and other conditions may occur, and patients may experience symptoms such as fatigue and pale complexion. The state of blood dilution can also cause this indicator to be low, such as after drinking a large amount of water or physiological increase in blood volume during pregnancy. At this point, the proportion of water in the blood increases, leading to a decrease in viscosity. The enhanced deformability of red blood cells can also affect the test results. In some hereditary diseases with abnormal red blood cell membranes, red blood cells are more likely to deform and pass through microvessels, leading to an abnormal increase in blood flow. Long term use of anticoagulant drugs such as warfarin sodium tablets, aspirin enteric coated tablets, etc. may also alter the rheological properties of the blood. Some patients with liver diseases may also experience a decrease in blood viscosity due to reduced plasma protein synthesis.

It is recommended to complete blood routine, iron metabolism, liver function and other tests for those with low whole blood reduced viscosity. Daily intake of iron rich foods such as animal liver and lean meat can be supplemented in moderation to avoid blood dilution caused by excessive drinking after vigorous exercise. If accompanied by symptoms such as dizziness and palpitations, seek medical attention promptly and receive targeted treatment under the guidance of a doctor, avoiding the use of blood supplements on one's own.
