Anemia Fact Sheet

  Printer Friendly PDF  

Anemia is a blood cell condition in which there is a deficiency of oxygen-rich red blood cells. A low level of hemoglobin, the iron-rich protein that carries the oxygen in red blood cells, signals the condition. Anemia can be chronic or it can be a temporary condition caused by other health issues, including treatments for cancer, hepatitis C, and HIV/AIDS. Anemia frequently remains undiagnosed because it is an underlying condition of other health issues, including cancer, cardiovascular disease, diabetes, HIV/AIDS, inflammatory bowel disease, chronic kidney disease, and rheumatoid arthritis.

At risk groups include:

  • Infants with inadequate amounts of iron
  • Children undergoing periods of rapid growth
  • Pregnant women
  • Pre-menopausal women

Statistics

  • One in 10 people age 65 and older has anemia.
  • Half of people in nursing homes have anemia.
  • Eight in 10 chemotherapy patients have severe anemia.
  • Half of patients in intensive care units have anemia, and three in four extended-stay seriously ill patients are anemic.
  • One in five pregnant women in the United States is anemic.
  • More than three-quarters of people with AIDs have anemia.
  • More than 40 percent of cardiac patients in the hospital have anemia.

Risk Factors

  • Low amounts of iron and certain vitamins caused by an iron-deficient diet
  • Loss of blood
  • Serious illnesses, including cancer, diabetes, heart failure, HIV/AIDS, inflammatory bowel disease, kidney disease, liver disease, rheumatoid arthritis, and thyroid disease
  • Long-term infections
  • Family history, including sickle cell anemia and thalassemias

Symptoms

  • Fatigue is the main symptom of most types of anemia
  • Weakness, dizziness
  • Irritability
  • Rapid or irregular heartbeat
  • Chest pain, shortness of breath
  • Headache
  • Paleness of the skin
  • Depression, loss of sexual drive, decreased work performance
  • Brittle fingernails
  • Cold hands and feet
  • Unclear thinking, inability to concentrate
  • Odd food cravings

Treatments
Anemia treatment increases the amount of oxygen in the blood. The exact treatment depends on the severity and type of the disorder, but can include:

  • Dietary and nutritional changes or supplements, including intake of B12, folic acid, and vitamin C. Iron can be replenished through foods like eggs, fish, meat, poultry, beans, green-leaf vegetables, and fruits
  • Medication, such as antibiotics or hormones
  • Procedures such as blood transfusions, blood and marrow stem cell transplants, or surgery
