Raynaud’s Disease
The constriction of blood vessels is a natural protection against the cold. The system in patients with Raynaud’s disease, however, is too sensitive and constrictions are too intense. Severe constriction of the small arteries causes a collapse of blood circulation in the affected body part. As a consequence, the limbs undergo unwanted physical changes.
The first obvious reaction is a waxy skin. If the attack continues, the lack of oxygen in the tissue causes blue skin color and the patient experiences tingling sensations and painful throbbing. Such an attack can last for several hours. Finally, the condition fades and blood will flow back into the arteries, causing a reddening of the skin. The disease can progress further, resulting in a prolonged or permanent interruption of the blood flow. The affected body parts, most notably the fingers, become permanently thin and shiny white. To make matters worse, nicotine and certain drugs or medication constrict blood vessels further, intensifying the symptoms.
Doctors generally recommend self-
Named after a French physician, the disease is a disorder that affects the blood vessels in extremities such as fingers, toes, ears, lips and nose. The vessels constrict spasmodically, thereby interrupting the blood flow to the relevant body part. In extreme cases, the blood flow almost stops. This can cause death and decay of body tissue (gangrene).
Low temperatures and emotional stress are common triggers of Raynaud’s disease. But it can also manifest itself as a secondary symptom to skin disorders such as lupus and sceloderma. Some users of vibratory tools, such as pneumatic hammers and chain saws, can develop the disease – especially when the tools are handled in cold conditions.
