Raynaud Syndrome and Raynaud Phenomenon

Alternate Names : Raynaud Disease

Overview, Causes, & Risk Factors | Symptoms & Signs | Diagnosis & Tests | Prevention & Expectations | Treatment & Monitoring

Raynaud syndrome is a condition that causes repeated episodes of tightening, or constriction, of the blood vessels called arteries. The tightening of the arteries interrupts the blood flow to the fingertips or toes. Raynaud phenomenon is a related condition that is linked to an underlying health problem.

What is going on in the body?

In both Raynaud syndrome and Raynaud phenomenon, the blood vessels that supply an area constrict. During an attack, little or no blood flow reaches affected areas, which become cold and pale. Attacks may last a few minutes or as long as several hours. They may be mild or severe. Rarely, the tissue of the fingers can die from complete blockage of a blood vessel.

What are the causes and risks of the condition?

Raynaud syndrome may be triggered by several factors, including the following:

  • cold
  • mental stress
  • repeated vibrations, as in workers who use power tools
  • smoking
  • strong emotion
  • Raynaud phenomenon is linked to underlying health problems, such as:

  • atherosclerosis, or blockage and hardening of the arteries
  • autoimmune disorders, such as scleroderma
  • Berger disease, which is marked by pain in the fingers or toes and occurs in some heavy smokers
  • carpal tunnel syndrome, a condition caused by pressure on the median nerve at the wrist
  • hypothyroidism, a condition caused by an underactive thyroid gland
  • injuries
  • Certain medicines can cause Raynaud phenomenon. These include:

  • beta-blockers used to treat high blood pressure
  • ergotamine used for migraine headaches
  • narcotics
  • over-the-counter cold medicines
  • Raynaud syndrome is five times more common among women than men. The disorder is usually diagnosed before age 40. In fact, 75% of the cases of Raynaud syndrome occur in women who are 15 to 40 years old. It occurs more often during the winter and in cold climates.
