Other Symptoms
Iron deficiency anemia can cause some other less common symptoms. The lack of oxygen to different tissues and muscles in the body might lead to anxiety. Fortunately, it can be improved when the levels of iron recover. Another sign is the unusual craving for non-food objects or strange foods, such as chalk, paper, dirt, or ice. Cold feet and hands can also occur when these parts lack necessary oxygen. Lastly, the immune system would not receive sufficient oxygen to fight against foreign invaders. This makes you more vulnerable to infections. [8]
