Healthy blood flow is vital for human wellbeing. This article lists some factors that affect normal blood flow the the human body.


Blood is one of the important body fluids which accounts for 8 percent of a human being's weight. It supplies essential substances to the cells. It also removes waste from the cells. Normal blood flow through the human body is necessary for healthy existence. Blood flows to a particular organ based on the need. Blood vessels are designed in such a way that they can change their diameter, there by regulating the blood flow. This is made possible by the vasoactive substances which are released by the cells surrounding the blood vessels. These substances constricts or dilates blood vessels based on the need.

Factors that affect normal blood flow

Here are some factors which affect normal blood flow in a human being:

Vascular dementia: This common form of dementia is an after effect of stroke or a series of strokes. Vascular dementia occurs when blood supply to the brain is interrupted by damaged vascular system. As a result of this the brain is deprived of oxygen and other nutrients. Patient suffers from thinking and memory related problems, confusion, dizziness, balancing problems, slurred speech etc.

Raynaud's disease: This disease results in brief periods of vasospasm (narrowing of the arteries), there by affecting the blood flow. Arteries carry blood from the heart to the different parts of the human body. This disease affects blood supply to fingers and toes. It is also known to affect blood flow to lips, ears, nose and nipples. But these are rare. During what is called as "Raynaud's attacks", the skin may turn white and then blue for a short time.

Use of marijuana: Research results have proved that use of marijuana affects blood flow to the brain. The velocity of blood flow was higher among the marijuana users. This is the reason why marijuana users find it difficult to think and remember. The study was conducted by American Academy of Neurology.

Hypertrophic cardiomyopathy: Also referred to as HCM, this disorder results in thickening of hear muscles. This obstructs blood flow there by affecting normal functioning of the heart.

Atherosclerosis: This disease is one of the main causes of death all over the world. Arteries of the person suffering from this ailment are hardened due to build up of fatty or mineral deposits (plaque). This leads to further complications like blood pressure and heart attack. Atherosclerosis if the primary cause of Coronary Artery Disease (CAD). Smoking, high fat diet, physical inactivity and stress can cause this disease.

Excessive use of caffeine: Studies have found that caffeine reduces the human body's ability to increase blood flow to the heart muscles on demand.

Diabetes: Patients affected by diabetes suffer from increase in blood sugar levels. The body converts these sugars into triglycerides (fatty substances). Triglycerides mix with the blood making it thicker and stickier. As a result blood flow slows down, delaying oxygen to various parts of the body.

Adherence to healthy diet and regular exercises keep the blood flow normal in the human body.
