Raynaud's

Reduced blood flow in response to cold or emotional stress, causing discoloration of the fingers, toes, and occasionally other areas. May also cause nails to become brittle.

About Raynaud's

Raynaud's is a rare disorder that affects the arteries. Arteries are blood vessels that carry blood from your heart to different parts of your body.

Raynaud's sometimes is called a disease, syndrome, or phenomenon. The disorder is marked by brief episodes of vasospasm (VA-so-spazm), which is a narrowing of the blood vessels.

Vasospasm of the arteries reduces blood flow to the fingers and toes. In people who have Raynaud's, the disorder usually affects the fingers. In about 40 percent of people who have Raynaud's, it affects the toes. Rarely, the disorder affects the nose, ears, nipples, and lips.

Overview

There are two main types of Raynaud's—primary and secondary.

In primary Raynaud's (also called Raynaud's disease), the cause isn't known. Primary Raynaud's is more common and tends to be less severe than secondary Raynaud's.

Secondary Raynaud's is caused by an underlying disease, condition...Read more about Raynaud's

Prazosin for Raynaud's phenomenon in progressive systemic sclerosis

Scleroderma is a connective tissue disease causing fibrosis and commonly affects the skin and internal organs such as the GI tract, lungs, kidney and heart. Most people with scleroderma also have raynaud's phenomenon (RP). RP is defined as vasospasm of arteries or arterioles causing pallor and at least one other colour change upon reperfusion such as cyanosis or redness. Primary RP occurs in the absence of causes such as connective tissue disease. Secondary RP occurs in people with underlying diseases that affect blood vessels especially scleroderma and lupus. The RP that occurs in scleroderma is often more severe in that there is not only vasospasm but also a fixed blood vessel deficit with intimal proliferation and therefore narrowing of the blood vessels. Raynaud's phenomenon may also be accompanied by digital ulcers which are possibly secondary to ischemia.

Ketanserin is a drug that has been studied in the treatment of Raynaud's phenomenon and associated conditions. It is not widely used however.

Raynaud's phenomenon is a disease that causes decreased blood flow and circulation to the extremeties. Symptoms include discolouration, pain, and in some severe cases ulceration of the hands and feet. It is most often triggered by cold, stress, and emotional discomfort. Primary Raynaud's phenomenon has no underlying disease associated with it. Secondary Raynaud's phenomenon is most often associated with scleroderma, but may also be related to systemic lupus erythematosus, mixed connective tissue disease, Sjorgen's syndrome, dermatomyositis, or rheumatoid arthritis. Scleroderma is a connective tissue disease causing hardening and commonly affects the skin and internal organs such as the GI tract, lungs, kidney and heart.

Terms to know

Arteries
A blood vessel that carries blood from the heart to tissues and organs in the body.
Blood Vessels
Tubes that carry blood to and from all parts of the body. The three main types of blood vessels are arteries, capillaries, and veins.
Rheumatologist
Doctors who diagnose and treat diseases of the bones, joints, muscles, and tendons, including arthritis and collagen diseases.
Systemic Circulation (Blood Circulation)
Systemic circulation is the part of the cardiovascular system which carries oxygenated blood away from the heart to the body, and returns deoxygenated blood back to the heart.
