The role of blood viscosity in the development and evolution of a variety of health conditions is often overlooked. Blood flow is necessary for delivering oxygen and nutrients to cells as well as clearing metabolic wastes. When blood flow is impaired, disease follows. Impairments in blood viscosity and flow are seen in atherosclerotic vascular diseases such as cardiovascular disease cerebrovascular disease. Studies also highlight relationships between blood viscosity and diabetes, metabolic syndrome, and cognitive impairment. This page allows our visitors to explore the connection between blood viscosity and these diseases, in addition to many others.
