June 2, 2025 - Hyperviscosity syndrome occurs when blood thickens so much that it doesn’t flow freely through blood vessels. This serious condition requires timely treatment.

June 12, 2025 - Normal plasma viscosity is between ... evidence of their underlying disorder. Those with myeloma will typically display a rouleaux formation on a peripheral smear and a large globulin gap, indicative of a significant paraprotein load....

April 27, 2025 - Learn what hyperviscosity is, what causes it, its symptoms, and how to treat it.

September 27, 2018 - Whole-blood hyperviscosity is seen in patients with extreme elevation of the red cell and white cell count. Phlebotomy of patients with primary and secondary elevation of the red cell count is a well-established therapy. Subjects: Clinical Trials and Observations, Lymphoid Neoplasia, Multiple ...

Confusion and mental status changes result from the increased viscosity of the blood and decreased cerebral blood flow. This sludging leads to segmental dilatation of retinal veins and retinal hemorrhages.

Recurring nosebleeds, headaches, and visual disturbances are common symptoms in patients with symptomatic hyperviscosity.16 Funduscopy is an important indicator of clinically relevant hyperviscosity. Among the first clinical signs of hyperviscosity are the appearance of peripheral and midperipheral ...

May 15, 2018 - Hyperviscosity syndrome is a condition in which blood is unable to flow freely through the arteries. This condition is most common in infants and children and can affect their growth by reducing blood flow to the vital organs. Read more about the symptoms and treatment of hyperviscosity syndrome.

September 1, 2023 - When blood becomes too thick, it can lead to clots and other complications. Here, learn more about why it happens and the effects.

Diabetes and kidney failure are chronic diseases that are associated with cardiovascular complications, while dyslipidaemia is a strong risk factor. Hyperviscosity is believed to be associated and managed with antiplatelet, but not routinely ...

Blood viscosity is increased by elevated concentrations of acute phase reactants and hypergammaglobulinemia in inflammation. These increase blood viscosity by increasing plasma viscosity and fostering erythrocyte aggregation. Blood viscosity is also ...

... Hyperviscosity syndrome is a medical emergency that requires prompt identification and treatment. · The classic triad of hyperviscosity syndrome is mucosal/skin bleeding, neurologic deficits, and visual disturbances. Although high serum viscosity leads to hyperviscosity syndrome, the ...

August 20, 2019 - An interesting theory proposes that watering down your blood can prevent heart disease. Don't overdo blood thinners.The old adage "Blood is thicker than water" makes sense for family ties. For the heart and circulatory system, though, thinner, more watery blood might be better.

This can cause red cells to stick together and form chains of several cells (rouleaux formation) within the microcirculation, which increases the blood viscosity. Because of the high interaction between the elements of blood when it is not flowing, a driving pressure significantly greater than ...

January 23, 2025 - Blood viscosity is determined by red blood cells and protein components in plasma. Measuring blood viscosity is highly valuable in assessing thrombotic disorders.

September 12, 2024 - Polycythemia vera is a rare blood disorder in which there is an increase in all blood cells, particularly red blood cells. The increase in blood cells makes your blood thicker. This can lead to strokes or tissue and organ damage.

Symptoms can include fatigue, chest pain, shortness of breath, and frequent headaches. If you're experiencing these symptoms, it could be a sign of an underlying cardiovascular issue, and it's crucial to seek medical ...

Blood viscosity is normally 1.5 cP, and once serum viscosity exceeds 4 cP, the hyperviscosity syndrome can manifest.19 In the case of Waldenstrom macroglobulinemia, this would generally correspond to an IgM level greater than 3 g/dL.18 · Patients present with bleeding, neurologic changes, visual changes, and constitutional symptoms as outlined in Table 1.20–22 The diagnosis is based on signs ...
