Pernicious anemia means that you do not have enough red blood cells. It happens when your body can't absorb vitamin B12 from food.
Your body needs vitamin B12 to make red blood cells. Red blood cells carry oxygen around your body. Vitamin B12 also helps your nerves work well.
Your doctor can treat this problem with vitamin B12 shots. You may also take vitamin B12 by pill or nasal spray.
