Types of Raynaud's

There are two major types of Raynaud's: Primary Raynaud's and Secondary Raynaud's.

Primary Raynaud's

Also known as Raynaud's disease, this condition occurs on its own and is not accompanied by other diseases. It is most commonly seen in young women in their teens and young adulthood. Although primary Raynaud's is thought to be hereditary, it is uncertain whether it is actually genetic or merely more readily recognised within families of people diagnosed with the disease.

Secondary Raynaud's

Also known as Raynaud's phenomenon, this type of condition occurs in less than 10% of cases. It develops as a secondary effect to other causes, including connective tissue disorders such as lupus (an autoimmune disease), scleroderma (a condition which causes hardening and thickening of the skin) and arthritis, along with other conditions such as carpal tunnel syndrome and obstructive arterial disease. Certain drugs may also cause secondary Raynaud's as a side effect, for example, decongestants, beta-blockers, anti-migraine medication, and occasionally, the contraceptive pill.

Raynaud's may sometimes result from a physical injury such as fractures or frostbite, or it may affect people who use their fingers and hands more than usual, such as typists or pianists.
