BlogDo cold hands and feet mean a serious venous problem?
Cold hands and feet are NOT related to vein problems. This condition is related to an abnormal response of the small arteries in the hands, feet, fingers, and toes to cool temperature. These small arteries normally spasm down in cold weather to retain body heat. As a consequence, the hands and feet get cold. In some people, this response is abnormally strong, and the arteries spasm down in normal temperatures, causing the hands and feet to feel cold much of the time. In extreme cases, this disorder is called Raynaud’s Syndrome, and in addition to feeling cold, the fingers and toes can turn red, blue, or white and can become numb.
Keeping the hands and feet warm with socks, gloves, and pockets is the best treatment. It is also important to keep the body warm. Rarely, a calcium channel blocker medication is prescribed to help prevent arterial spasm.
