Serious Causes Linked To Poor Circulation

Raynaud's Disease

Raynaud's disease reduces circulation in the hands and feet, and the syndrome is most common in women and in those who live in cold climates. Patients with Raynaud's disease usually experience color changes in their hands and feet in response to cold or stress, and they may also have numbness and tingling. These symptoms normally come in episodes that may last for several minutes. After the patient has warmed up or resolved a stressful situation, it can take roughly fifteen minutes for normal circulation to return. To diagnose Raynaud's disease, doctors may examine the patient's nails under a magnifying glass to check for deformities in the capillaries. Blood tests could be needed to determine whether the patient's symptoms are caused by an underlying autoimmune disease or not. To treat this syndrome, doctors may prescribe vasodilators and calcium channel blockers, and some patients find exercise, stress management, and avoidance of rapidly changing temperatures all help improve their symptoms.
