A condition in which blood flow to the body's tissues is reduced by a malfunction of the nerves that regulate the constriction of blood vessels.When attacks occur as part of a disease (as in scleroderma), it is called Raynaud phenomenon.

∙ 12y agoIntermittant ischemia (deficient blood flow) of the fingers or toes, sometimes also affecting the ears and nose.
The phenomenon in which, a disorder causing discoloration of the fingers, toes, and occasionally nose and earlobes is discussed; is known as Raynaud's Phenomenon.
The classic cause is cold atmosphere; but sometimes mental stress and/or nervousness are the triggers as well.
When patient's body is exposed to cold temperatures,
the blood vessels of affected area starts to constrict.
Once the vessels are reduced in size, the blood flow decreases.
As a result, the skin turns pale or white, because of lack of blood (vasoconstriction).
If the vasoconstriction is more severe the tissues from respective organs, don't get enough oxygen.
So, the nails and/or skin turns blue in colour (hypoxia).
In sever cases, (or in extreme cold atmosphere), the blood/oxygen supply decreases markedly,
this lack of oxygen causes tingling feeling to move on to to become painful feeling.

Can Raynaud's phenomenon cause Secondary vasculitis?
Raynaud's phenomenon can cause Secondary vasculitis
What usually precedes Scleroderma?
Raynaud's phenomenon
How is Raynaud's disease classified?
Raynaud's disease can be classified as one of two types: primary (or idiopathic) and secondary (also called Raynaud's phenomenon).
What kinds of Raynaud's syndrome are there?
Raynaud's syndrome can be classified as one of two types: primary, or idiopathic (of unknown cause) disease; and secondary, which is also called Raynaud's phenomenon.
What happens in Raynaud's phenomenon?
In Raynaud's phenomenon, the affected extremities turn white, then blue, and red as the blood supply is cut off. The color changes are accompanied by numbness, tingling, burning, and pain.
What is the difference between Raynaud phenomenon and Raynaud disease?
When attacks of Raynaud's occur in the absence of other medical conditions, it is called Raynaud disease. When attacks occur as part of a disease (as in scleroderma), it is called Raynaud phenomenon.Answer 2:The phenomenon in which, a disorder causing discolouration of the fingers, toes, and occasionally nose and earlobes is discussed; is known as Raynaud's Phenomenon.Raynaud's Disease, or "Primary Raynaud's", is diagnosed if the symptoms are idiopathic, that is, if they occur by themselves and not in association with other diseases.Raynaud's Syndrome, also called as Raynaud's Secondary is the name for the condition when it is result of an underlying problem.
What term describes intermittent attacks of paleness cyanosis and redness of the fingers and toes?
This is known as Raynaud's Phenomenon. It can start in puberty and goes to the age of 30. Mostly it affects women and is due to family history.
Is raynauds fatal?
almost always, at least according to doctors and science
What are some symptoms of Raynaud's phenomenon?
The most common symptoms of Raynad's phenomenon are often cold feet and hands and can often be mixed up with frostbite. But it should be known that Raynad's phenomenon is not the same as frostbite!
A peripheral arterial occlusive disease in which intermittent attacks are triggered by cold or stress?
Raynaud's Syndrome.
What is a good science fair title dealing with raynaud's phenomenon?
A good title for a scientific work should be descriptive of that work, without including unnecessary information. Think about what you are trying to show, and state it plainly. Depending on the exact content of your project, the name could vary. One example is: An Introduction to the Physiology of Raynaud's Phenomenon
What are some things that cause Raynauds disease?
The cause of Raynaud's phenomenon is not completely understood. It is known that the constriction of blood vessels in affected areas (known as vasospasm) can be brought on by exposure to cold and excessive stress, temporarily limiting blood flow. Some researchers are also studying if genetics is related to Raynaud's phenomenon.Conditions and factors which cause secondary Raynaud's phenomenon include:SclerodermaLupusRheumatoid arthritisSjogren's syndromeMixed Connective Tissue DiseaseDermatomyositisPolymyositisRepetitive stressSmokingCertain medicationsHypothyroidism
