Yes, there may be an underlying reason why your feet are always cold. If you find that you consistently have cold feet even when the weather isn’t too chilly, you may want to see a doctor for an evaluation and recommendations.
The reason we normally have cold feet and hands is the body’s thermoregulation. The nervous system redirects blood away from the periphery and towards the core body and major organs. This is a survival mechanism and is normal.
However, should you develop consistent and specific patterns of cold feet that aren’t related to weather or activity, you should get a podiatrist to evaluate your feet to make further recommendations. Things to note prior to an appointment could include: changes in skin appearance (discoloration, swelling, hair loss, or even sores), persistent coldness in mild temperatures, numbness/tingling, or leg discomfort when walking.
Some medical conditions that can cause cold extremities include peripheral vascular disease or even Raynaud’s phenomenon. Peripheral vascular disease has been discussed here before, but in short, it occurs when arteries become narrowed or blocked, limiting blood flow to the lower extremities. Usually, we see this manifest in the foot with hair loss, painful/slow-healing ulcers, or leg pain with activity. Raynaud’s phenomenon is commonly due to a vascular spasm, which drastically reduces blood flow in response to cold or stress.
Other causes of cold extremities include low thyroid function (hypothyroidism). This is commonly when your thyroid doesn’t produce enough hormones, slowing down metabolism. This leads to colder extremities commonly. Other causes can be vitamin B12 deficiency or even anemia. These conditions affect your blood’s ability to carry oxygen, which leads to cold extremities.
Overall, those at risk include smokers, people with diabetes, those with autoimmune disorders, and those with poor circulation due to cardiovascular disease. Once evaluated by your doctor, recommendations will be made, such as blood tests, imaging, or even referral to a vascular specialist.
Treating cold feet may involve conservative measures. This includes treating blood pressure, diabetes, high cholesterol, dieting, exercise, or taking medications. If one smokes, cessation is critical. Other treatments can include surgery, such as an angioplasty, to improve blood flow.
It is important to pay attention to your body and notice changes. Should you develop consistently cold feet and have any questions or concerns about having any of the above conditions, see us at Marvel Foot and Ankle, and we will be happy to make recommendations.
