Complete Guide to Reynaud Disease Part 1

Reynaud disease also known as Reynaud’s disorder, Reynaud’s syndrome or Reynaud phenomenon is a very rare condition that generally affects arteries. Arteries are blood vessels that are responsible in supplying blood from the heart to various parts of the body. With Reynaud disease, the arteries found in the skin will narrow thus resulting to limited blood circulation to fingers and toes. Aside from skin and toes, it may also affect the nose, ears and lips.

Due to lack of blood supply, the affected area may turn to white then bluish in color. As blood supply gradually returns, the person may feel numbness.

This rare condition is often seen living in those places that have colder climate and more women are at risk of developing this disorder. However, there are some cases, where a person with Reynaud may not also be able to stand in rooms with cold air conditioning or cannot even hold a cold glass of water.

Clinically, there are two classifications: the classified primary Reynaud and the secondary Reynaud. Between the two, primary is more common and less severe than secondary.

  • Severe cold temperature. When body is exposed to severe cold temperature, the blood supply to the fingers and toes are lesser in order to preserve the body temperature. However, with Reynaud, the body’s reaction to cold weather is overly exaggerated.
  • Stress is another possible culprit of the attack. When a person with Reynaud is under stress, the body reaction is also exaggerated thus leading to symptoms of Reynaud.
  • Injuries to hands and feet like frostbite or fracture can also be another cause.

  • Rheumatoid arthritis is often related to secondary Reynaud. Oftentimes, the appearance of Reynaud is the initial sign of inflammation of joints
  • Sjogen syndrome can also be underlying cause. Some cases of Sjogen syndrome also feel bothersome symptoms of Reynaud phenomenon.
  • Lupus, an autoimmune disease, is often a common cause of Reynaud. Most cases of lupus also suffer from the secondary Reynaud.
