Iron is an essential nutrient for your body which you can get from your food. It is needed for your mental and physical health and to keep your energy levels up. Sometimes your body's demand for iron can outstrip supply, and this can lead to iron deficiency. Iron deficiency causes many symptoms including fatigue, dizziness, and shortness of breath. If you are experiencing symptoms it is important that you talk to your doctor so that they can investigate what is causing them. If tests show that your iron levels are low, your doctor may recommend iron therapy.
