Restless Leg Syndrome
Iron deficiency anemia has been associated with restless legs. It is characterized by a strong and uncontrollable urge to move your legs while resting. It can also cause itchy sensations or unpleasant crawling in the legs and feet. It usually gets worse at night, meaning that affected people may strive to get much sleep. The causes of this syndrome are not fully known. However, it is believed that iron-deficiency anemia can be one underlying cause of restless leg syndrome in up to 20 to 25% of people, and the lower the levels of iron in your red blood cells, the more severe will be the symptoms.
