Risk Factors
Anemia is a condition in which a person has a lower-than-normal red blood cell count. People who are most at risk for anemia include those who:
Have a chronic illness: People who have chronic illnesses, such as kidney disease, HIV/AIDS, cancer, or heart failure, are more likely to be anemic. These diseases can cause the body to not produce enough red blood cells, or can cause the body to break down red blood cells more quickly than normal.
Have a poor diet: People who do not consume enough iron, folate, or vitamin B12 in their diets are more likely to develop anemia. Iron is found in foods such as lean red meats, poultry, fish, legumes, and nuts. Folate and vitamin B12 are found in foods such as leafy green vegetables, eggs, dairy products, and fortified cereals.
Have a blood disorder: People who have certain blood disorders, such as sickle cell anemia or thalassemia, are more likely to be anemic. These disorders cause the body to not produce enough healthy red blood cells.
Are pregnant: Women who are pregnant are at an increased risk of developing anemia due to the increased demands on their body.
