RAYNAUD'S DISEASE

Post by pmmutiti on Tue Jun 24, 2008 5:32 pm

Raynaudís phenomenon is characterized by periods of disrupted blood flow in the fingers caused by exposure to cold or stress. The condition s relieved by warming the affected parts. It is estimates that about 4 % of the US. Population suffers from the primary form of this phenomenon, the so-called Raynaudís disease. Secondary Raynaudís phenomenon occurs in association with connective tissue disease (progressive systemic sclerosis)

Researcher at Albany medical college now report that supplementation with marine oils significantly reduces the symptoms of Raynaudís disease (primary Raynaudís Phenomenon) but has no beneficial effects in Secondary Raynaudís Phenomenon.

Peter Mwaura Mutiti : Teaching old blood cells new tricks:
When you hear someone mention circulation you probably think of the heart and major arteriesóand for good reason. Circulatory disorders such as hypertension (high blood pressure) and atherosclerosis (hardening of the arteries) are major risk factors for heart disease, heart attacks, and stroke.

But thereís more to it than that. With all the attention on the heart and arteries, itís easy to overlook serious health problems affecting the smallest components of the circulatory systemómicroscopic blood vessels called microcapillaries, where the critical exchange of oxygen and nutrients actually takes place. If blood isnít flowing through this web properly, it can trigger all sorts of health problems, many of which may not seem related to circulation at all.

A number of factors contribute to poor circulation as we age. Arteries and veins become stiff and congested as cholesterol and calcium plaques accumulate and restrict blood flow. Spasms in the smooth muscles surrounding the circulatory arteries and veins can also choke off circulation. These same processes also occur in our microcapillaries, reducing microcirculation and impairing the critical exchange of nutrients and gases in tissues and major organs.

This problem only gets worse as we get older because of changes in the composition and structure of blood cells. As you reach middle age, the blood starts to thicken and congeal as platelets and blood proteins make cells sticky. Plus, the spleenóthe organ that removes old, damaged blood cells from circulationóbegins to slow down with age, which means new, healthy blood cells are replaced at a sharply reduced rate. And to make matters even worse, as blood cells age, they become stiff and no longer appear round and evenly shaped. This makes it harder for them to pass smoothly through the capillaries. In fact, the angular, jagged shape of the old cells can damage the fragile microcapillaries even further.

Eventually, these age-related changes take their toll on the microcapillaries, reducing circulation to the tissues and blocking the flow of nutrients and oxygen. Removal of carbon dioxide and other metabolic waste products is also hindered. This leads to a slow buildup of metabolic garbage that can gradually bury the cells in their own waste products. In time, the cells, poisoned by their own metabolic byproducts, begin to waste away and ultimately cease to function altogether.

The combined effect of poor circulation and old blood contributes to a host of symptoms, including deep fatigue, fuzzy thinking, frequent infections, and lowered sex driveóall conditions usually considered just ďnormal parts of aging.Ē

If circulation doesnít improve, it can lead to more serious conditions, such as high blood pressure, heart attack, stroke, diabetes, and arthritis. But giving your body a fresh supply of healthy blood may target all of these problems and more.
