March 13, 2023 - Hyperviscosity syndrome (HVS) is an oncologic emergency that classically presents with the triad of neurological deficits, visual changes, and mucosal bleeding. Elevated blood viscosity results from either red blood cell shape deformity or a pathological increase in serum proteins, red blood ...

June 2, 2025 - Multiple factors can increase blood viscosity. Your blood may thicken if you have irregularly shaped red blood cells.

Because of their large size (molecular ... has signs or symptoms of hyperviscosity syndrome, though levels are often slow to be reported and erratic owing to a lack of standardization in most clinical laboratories.16 As such, serum IgM levels may be more expedient and relied upon. Patients typically become symptomatic at serum viscosity levels of 4.0 cp and above, which relate to serum IgM levels above 6000 mg/dL.124,125 Patients may be symptomatic at lower serum viscosity ...

Low flow states permit increased molecular interactions to occur between red cells and between plasma proteins and red cells. 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 ...

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 ...

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.

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

June 12, 2025 - Plasmapheresis may be used to decrease viscosity in the case of myeloma, whereas leukapheresis or phlebotomy may be employed in a leukemic or polycythemic crisis, respectively. Blood transfusions should be used with caution as they can increase serum viscosity.

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.

May 1, 2001 - Abstract. We planned a study to research the relations among blood pressure (BP), viscosity, and temperature in healthy subjects and among BP, viscosity, a

May 3, 2025 - Hypotension is characterized by a decrease in systemic blood pressure below normal values. As this condition is often asymptomatic, it may go undiagnosed. Normal blood pressure is typically considered to be between 90/60 and 120/80 mm Hg, with values below 90/60 mm Hg classified as hypotensive ...

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.

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 ...

September 27, 2018 - Plasma hyperviscosity is a rare complication of both monoclonal and polyclonal disorders associated with elevation of immunoglobulins. Asymptomatic patient

June 19, 2025 - Diseases of the circulatory system are more common than heart disease and cancer, accounting for almost 40% of deaths. Learn more.

Hyperviscosity syndrome (HVS) refers to the clinical sequelae of increased blood viscosity. Increased serum viscosity usually results from increased circulating serum immunoglobulins and can be seen in such diseases as Waldenström macroglobulinemia and multiple myeloma.

February 1, 2014 - OBJECTIVE. Blood viscosity (BV) is higher in diabetic patients and might represent a risk factor for the development of insulin resistance and type 2 diabe

Whole blood is a non-Newtonian fluid, which means that its viscosity depends on shear rate. At low shear, blood cells aggregate, which induces a sharp increase in viscosity, whereas at higher shear blood cells disaggregate, deform and align in the ...
