It’s not just the cold weather. Cold feet can occur for many reasons including poor circulation in the lower legs and feet.
Cold sensations to the feet can come from poor circulation, disorders of the nervous system, cold exposure injuries such as frostbite, and decreased metabolism from a low thyroid condition (hypothyroidism or underactive thyroid).
If your feet are cold all the time, your thyroid may not be working properly, and it may not be producing enough hormones to regulate your metabolism (hypothyroidism). Your body’s ability to generate heat is affected and that’s why your hands and feet are always cold. Other side effects of hypothyroidism can be fatigue, weight gain and possibly hair loss.
Depending on the cause of the symptoms, coldness in the feet can be accompanied by other symptoms, including pain, numbness, changes in skin colour, or a “pins and needles” tingling sensation. Other diseases that can cause cold feet symptoms include diabetes, peripheral vascular disease, Raynaud’s phenomenon, and neuropathy of any cause.
Conditions such as PVD (Peripheral Vascular Disease) in which blood flow is limited due to arterial blockage or narrowing, can give the foot a numb and/or cold feeling. Other conditions that may cause cold feet include certain medications or nerve conditions.
