The biggest difference between thick blood and high blood lipids is that high blood lipids can cause thick blood. But blood stickiness can have other causes besides high lipids. Blood stickiness is an increase in the viscosity of the blood, and the patient develops hyperviscosity and is prone to thrombotic or embolic disorders. In clinical practice, there are various causes of blood stickiness, including the increase in the number of various blood cells, such as the increase in the number of red blood cells, the increase in the number of platelets, and the increase in the number of white blood cells, all of which may cause an increase in blood stickiness; the decrease in the deformability of red blood cells may also cause an increase in blood stickiness; changes in the various solute components in the plasma may also cause blood stickiness, including the increase in the concentration of blood lipids, which may cause blood stickiness; the increase in the concentration of blood lipids may cause blood stickiness; and the increase in the concentration of blood lipids may cause blood stickiness. Increased blood lipid concentration can cause blood stickiness; increased blood glucose concentration can also cause blood stickiness; increased fibrinogen concentration in plasma and increased immunoglobulin concentration can also cause blood stickiness. Therefore, thick blood includes a variety of causes, including increased lipids, which is only one of the possible causes of thick blood.
