Many people don't get enough iron in their diet, which can cause all kinds of symptoms.
Iron is needed to make hemoglobin, which enables red blood cells to carry oxygen around the body.
If your body doesn't have enough hemoglobin your tissues won't get enough oxygen to allow them to function properly, which leads to a condition called anemia.
