The US Food and Drug Administration (FDA) has approved a new medication to treat anemia.

Iron deficiency has been associated with autism in past studies, such as one published in Pediatrics in 2012. And children of mothers who have too little iron during pregnancy may also have a higher risk of getting this condition.

Iron can reduce fatigue and prevent anemia. Now, women may have another reason to add more of the mineral to their diet: to ease PMS symptoms.

Women who lose a lot of blood while giving birth may end up with acute postpartum anemia. A blood transfusion can help them feel a little less tired but may not be necessary.
