If your legs and feet always feel cold, you can consider the following reasons: lower extremity circulatory disorders, hypothyroidism, and hypokinesia. 1. Lower extremity circulatory disorders: this is the most common cause of cold legs and feet, which can be seen in lower extremity vascular valve closure insufficiency, thrombotic occlusive vasculitis, arteriosclerosis occlusive disease, etc., which can cause stagnation of blood in the lower extremities, insufficient blood supply, resulting in tissue ischemia and hypoxia, thus feeling cold legs and feet. 2. Hypothyroidism: When the thyroid gland is hypothyroidized, the metabolic function of the body is reduced, and the symptoms of cold legs and feet may appear. 3. Hypothyroidism: when hypothyroidism occurs, the body’s metabolic function decreases, which can lead to symptoms of cold legs and feet. When the legs and feet feel cold all the time, and the symptoms continue to be unrelieved, it is recommended to consult a doctor in a timely manner, to clarify the diagnosis and receive appropriate treatment.
