Thick blood or hypercoagulability is a condition where the blood is thicker and stickier than usual. When a person has hypercoagulability, they are prone to excess blood clots. The condition is the result of an abnormality in the clotting process. Among abnormalities that cause thick blood is an imbalance of proteins and cells responsible for blood clotting. Thick blood can obstruct the movement of oxygen, hormones, and nutrients in the body, preventing them from reaching tissues and cells.
APDeF yahoo. Complications of chronic hypoxia, including erythrocytosis, hyperviscosity, abnormalities of hemostasis, cerebral abscesses, stroke, and endocarditis, are among the most common consequences of cyanotic heart disease in adults. Treatment of hyperviscosity secondary to erythrocytosis in cyanotic heart disease is controversial. Data is limited but suggest that phlebotomy has the potential to increase exercise capacity, reduce the symptoms of hyperviscosity, and reduce the potential risk of vasoocclusive disease in selected patients with polycythemia secondary to cyanotic heart disease. Unfortunately, repeated phlebotomy can quickly lead to iron deficiency, resulting in microcytic erythrocytes that induce higher viscosity than normocytic erythrocytes, which may increase the risk for venoocclusive events. There are limited data on the use of hydroxyurea to suppress erythrocytosis in this patient population.
Is blood like your waistline - the thinner, the better?
Hyperviscosity syndrome HVS is a combination of clinical signs and symptoms related to increased blood viscosity. HVS can also be secondary to increased cellular components due to leukemia or myeloproliferative disorders. The classic triad of symptoms includes neurologic abnormalities, vision changes and mucocal bleeding.
If you're at all concerned about heart health, you probably have a good understanding of cholesterol and blood pressure, and likely know your numbers. But there may be another critical blood-related issue to consider — blood viscosity, or blood thickness. According to a health report from Harvard University, people with thicker, more viscous blood may be at a greater risk for a heart attack or for developing heart disease. Despite living a healthy, active lifestyle, she had a heart attack at age Her doctors suspected blood thickness shouldered part of the blame.
