If your feet are always cold, there may be an underlying medical condition to blame. There are many different conditions that can make it hard to keep your feet warm. Many of these diseases make your hands cold as well. Some are serious conditions that can be life-threatening. If you have this symptom, talk to a doctor who can determine what is causing your feet to feel cold.
Raynaud's Phenomenon
The condition called Raynaud's phenomenon occurs when cold temperatures or stress make the blood vessels in your feet and hands constrict, says the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Less blood is getting through vessels which can make your feet feel cold. Your toes may become pale or turn red or blue. Once the blood vessels open up again, your skin color and temperature will usually return to normal. This condition can occur by itself or be a symptom of another disease. When Raynaud's phenomenon occurs by itself, there is usually no known cause.
Diabetic Peripheral Neuropathy
If you have diabetic peripheral neuropathy, it means that high levels of blood sugar in your body have caused damage to the nerves and blood vessels that supply the feet. This will prevent your body from properly regulating temperature. According to the National Diabetes Information Clearinghouse, you may also have pain, numbness and tingling sensations in your lower extremities.
Peripheral Artery Disease
Peripheral artery disease, or PAD, is a condition in which the arteries in the legs become narrowed and blocked. This usually occurs due to plaque buildup. Because of the restriction in blood flow, the temperature of your feet will be much cooler then the rest of your body. If the affected arteries are just in one leg, then there will be a temperature difference between both feet as well. If you think you have PAD, the American Heart Association recommends also being on the lookout for leg pain and cramps that get worse with activity, and cuts or sores on your feet that do not heal properly.
Hypothyroidism
If your thyroid gland is not producing enough hormone, your metabolism may slow down. This includes circulation. This can lead to feeling cold all over, even in your feet. If you have hypothyroidism, the Hormone Foundation says that you will also feel tired, sluggish, experience weight gain and many other symptoms. This condition can be diagnosed through a blood test. There are medications to help treat hypothyroidism.
