Cold, bluish-purple feet can indicate poor circulation, but it is just one of several potential causes for the condition, the medical name for which is cyanosis. While cold and discolored feet and hands may mean you suffer from poor circulation, that situation is actually uncommon, the University of Alabama-Birmingham reports.
What Happens
Your feet feel cold and appear purple in color because of a lack of properly oxygenated blood. Oxygenated blood appears red in color, but blood lacking ample oxygen is bluish-red and can look purple through the skin.
Cyanosis From Poor Circulation
When cyanosis develops because of poor circulation, it typically results from an underlying medical condition such as heart disease or congestive heart failure. In these cases, the feet and other extremities become cold and discolored because the body sends available blood to the vital organs. People who suffer from the condition also may experience such symptoms as fluid buildup in the legs and feet, decreased urine output and mental confusion. These symptoms can indicate acute heart failure and require medical evaluation.
Other Causes
Poor circulation is only one of many causes for cold and discolored feet. Some causes are temporary and no reason for concern. For example, being exposed to cold temperatures or cold water can cause cyanosis, MedlinePlus reports. Other potential causes include abnormal hemoglobin levels, blood clots, toxins such as cyanide and various lung conditions that affect how blood becomes oxygenated.
When to Seek Treatment
Cold, purplish feet resulting from being exposed to cold typically resolve quickly on their own. However, when the condition does not resolve, you should seek medical treatment to have the condition assessed. Cyanosis accompanied by breathing difficulties, chest pain, fever, mental confusion or a cough producing dark-colored mucous requires immediate medical attention. Otherwise, schedule an appointment with your medical practitioner to discuss your condition.
