Hematocrit is the most powerful determinant of blood viscosity and is determined by plasma volume and red cell mass.  Blood viscosity is under homeostatic control via regulation of hematocrit.  The regulatory pathway is as follows:  increased blood viscosity increases total peripheral resistance (...

Important evidence for the link between blood viscosity and cardiovascular events was provided by the Edinburgh Artery Study in a random population of 1,592 men and women aged 55 to 74 years, who were followed over a mean period of 5 years. After adjustment for age and gender, mean values for both...

Cardiovascular disease is the number one cause of death in the industrialized world. Despite the fact that over the past twenty-five years significant advances have reduced the frequency of this killer, the etiology, or root cause, of cardiovascular disease remains elusive. It increasingly appears...

Study Shows That Prehydration Attenuates Rise in Blood Viscosity Due to Dehydration Research published in the journal Aviation, Space, and Environmental Medicine demonstrated that dehydration increases systolic blood viscosity by 9.3% and diastolic blood viscosity by 12.5%. The results are from a...

Last year, 64% of women and 50% of men who died suddenly of a heart attack had no prior knowledge of their heart disease. Forty to fifty percent of all heart attack patients have a “normal” cholesterol profile. As NDs, we recognize that cholesterol – even abnormally high cholesterol – is not...

I am an internal medicine physician who has been practicing hospitalist medicine for 5 years now. I have been interested in nutrition and alternative medicine ever since meeting my wife during medical school who is a naturopathic doctor. One night while listening to the documentary Forks Over...

Increasing evidence supports the importance of hemodynamic forces that are directly related to the work of the heart as the primary triggering event of atherosclerosis and atherothrombosis. The factors that primarily determine the work of the heart include systolic blood pressure (BP), blood...

A quick search on the PubMed database reveals nearly 1,000 scientific papers linking blood viscosity to cardiovascular disease events and risk factors. In fact, increased blood viscosity is the only biological parameter that has been linked with all of the other major cardiovascular risk factors,...

A study conducted at the University of Pittsburgh and published in Clinical Hemorheology and Microcirculation demonstrated on average 62% higher systolic blood viscosity and 25% higher diastolic blood viscosity in men over premenopausal women.  Premenopausal women have lower hematocrit and improved...

Arterial Stiffening Increased arterial stiffness accelerates atherosclerosis by increasing peak arterial blood velocity, increasing Reynolds number, which indicates the propensity for a flowing fluid to develop pools and eddy currents in association with changing arterial geometry. In the normally...
