Anemia is more common in woman and woman who are pregnant. It is also more common in older adults who are sick and infants less than 2 years old.
Other factors that may increase the risk of anemia include:
Poor diet low in iron, vitamins, and minerals
Blood loss may be due to periods, surgery or injury
Chronic or serious illness
Family history of inherited anemia such as sickle cell anemia and thalassemia
Anemia may cause:
Shortness of breath
Coldness in the hands and feet
Rapid or irregular heartbeat
You will be asked about your symptoms and health history. A physical exam will be done. Blood tests will show how many RBCs there are and if they are healthy. Other tests may be needed to look for causes.
The goal of treatment is to increase healthy RBCs. The exact steps will depend on the cause. Underlying causes will be treated. Options to help increase the level of RBCs include:
Foods rich in iron, vitamin C, vitamin B12, and folate may be recommended. Vitamins or iron supplements may also be added.
Medicine may help to increase the amount of RBCs the body can make.
Healthy blood from a donor may be needed. It will increase RBCs quickly.
The effect will not last if the cause of anemia is not treated.
Bone Marrow or Stem Cell Transplant
RBCs are made in the bone marrow. Problems with the bone marrow can cause anemia. A transplant would help to grow new healthy bone marrow.
This procedure carries risk. It is only done in severe cases of anemia.
A diet rich in iron and vitamins may help to prevent some types of anemia.
