What causes cold feet?
Cold feet can be a symptom of several conditions, including nerve damage (called peripheral neuropathy), sometimes seen in diabetes (a chronic disease that affects your body’s ability to use sugar for energy), chronic alcohol abuse, or in certain vitamin deficiencies. Cold feet can also be a symptom of poor circulation of the blood to these distant, or peripheral, parts of the body.
Circulatory causes of cold feet
Cold feet may be caused by peripheral artery disease (PAD), also called peripheral vascular disease, (PVD), which is a narrowing or blockage of arteries due to a buildup of fat and cholesterol on the artery walls, a condition which limits blood flow to the extremities.
Neurologic causes of cold feet
Cold feet can also be caused by nerve damage (peripheral neuropathy) caused by:
- Certain vitamin deficiencies
- Chronic alcohol abuse
- Diabetes (chronic disease that affects your body’s ability to use sugar for energy)
