The symptoms of mild, easily treated anemias, respond quickly to treatment and improve in just a few days.  The symptoms of chronic anemias, such as sickle cell anemia, come and go. Anemia associated with a chronic disease usually improves or worsens as the disease improves or worsens.

Follow your doctor's instructions. Take your medicine as prescribed.

The prevention of anemia depends on the cause. If your anemia is caused by a deficiency in your diet, eating foods rich in the missing nutrient will help to prevent a recurrence.  It is important not to get dehydrated (that is, not to lose too much body fluid) during hot weather, exercise, or illness. Dehydration can trigger a sickle cell crisis. Genetic counseling is important for families with inherited anemia.
