Hyperviscosity

Hyperviscosity is a medical condition characterized by an increase in the viscosity, or thickness, of the blood. This can lead to a variety of symptoms and complications, including bleeding, blurred vision, and neurological disorders.

Causes

Hyperviscosity can be caused by a number of different conditions, including polycythemia vera, multiple myeloma, and Waldenstrom's macroglobulinemia. These conditions can cause an increase in the number of red blood cells, white blood cells, or proteins in the blood, leading to increased blood viscosity.

Symptoms

The symptoms of hyperviscosity can vary depending on the underlying cause and the severity of the condition. Common symptoms can include fatigue, headache, shortness of breath, and blurred vision. In severe cases, hyperviscosity can lead to stroke or heart attack.

Diagnosis

Diagnosis of hyperviscosity typically involves a combination of physical examination, medical history, and laboratory tests. These tests can include a complete blood count (CBC), blood viscosity test, and serum protein electrophoresis.

Treatment

Treatment for hyperviscosity typically involves addressing the underlying cause of the condition. This can include treatments such as chemotherapy, plasmapheresis, or blood transfusion. In some cases, medications may be used to reduce the viscosity of the blood.
