Cold feet can occur for many reasons, including poor circulation, hypothyroidism, cold exposure injuries, nervous system disorders, diabetes and Raynaud’s phenomenon, says Melissa Conrad Stöppler, M.D., on MedicineNet. Some conditions that cause cold legs include acanthocheilonemiasis, aortic coarctation, Leriche’s syndrome and mansonella ozzardi infection, says Right Diagnosis.
Cold exposure injuries, such as frostbite, cause long-term blood vessel damage. Individuals who suffer with diabetes and have elevated blood sugar may experience narrowing arteries that weaken the blood supply. This causes cold feet, says Melissa Conrad Stöppler, M.D. Raynaud’s phenomenon is a narrowing of blood vessels due to nerve sensitivity to cold temperatures.
