Men with cold feet should be alert to lower extremity arterial embolism, peripheral nerve dysfunction, venous embolism and endocrine system diseases. 1. Lower extremity arterial embolism: when lower extremity arterial embolism occurs, the blood in the blood vessels of the lower extremity is not filled smoothly, resulting in cold lower extremities. 2. Peripheral nerve dysfunction: If the distribution of peripheral capillaries is less or the capillaries are not developed, it can cause peripheral nerve dysfunction. 3. Venous embolism: when venous embolism occurs, venous blood return is blocked, resulting in lower limb temperature reduction. 4. Endocrine system diseases: when peripheral vascular disease occurs in diabetic patients, the lower extremity blood vessels will be narrowed or occluded; hypothyroidism, the body’s metabolism is slowed down, which can also cause cold hands and feet and other conditions. When the male feet cold, please go to the regular hospital in a timely manner, to clarify the cause of the disease, follow the doctor’s instructions for treatment.
