Aside from joint symptoms, anemia is the most common problem for people with rheumatoid arthritis.2,3 Studies show as many as 60% of people with rheumatoid arthritis are anemic.1
What causes anemia in people with rheumatoid arthritis?
There can be many reasons a person with rheumatoid arthritis experiences anemia. One cause is inflammation associated with rheumatoid arthritis. Inflamed tissues secrete small proteins that have effects on iron metabolism, bone marrow, and erythropoietin production by the kidneys (a hormone that controls production of red blood cells). Hemoglobin is carried by red cells, but when there are not enough red cells, your body’s organs do not get enough oxygen. In addition, many people with rheumatoid arthritis do not have enough iron available to get into red blood cells. This iron deficiency is usually caused by menstrual bleeding, digestive tract bleeding or a problem getting the iron from within the bone marrow into the red blood cells. Drugs used to treat rheumatoid arthritis (nonsteroidal anti-inflammatory drugs, prednisone and other drugs) are some of the causes of bleeding from the digestive tract.1-31-3
What are the effects of untreated anemia in people with rheumatoid arthritis?
Studies show people who have both rheumatoid arthritis and anemia tend to have more severe arthritis than people without anemia. They are more likely to have serious joint damage and to need anti-inflammatory drugs.4
How do I know if I have anemia?
The best way to determine if you have anemia is to discuss your blood counts and changes in hemoglobin and hematocrit with your doctor. Symptoms usually develop when anemia is moderate to severe, and can include fatigue, weakness, pale skin, chest pain, dizziness, irritability, numbness or coldness in your hands and feet, trouble breathing, a fast heartbeat, and headache. It is important to see your doctor on a regular basis in order to be tested for possible anemia.
What treatments are available to help me?
Studies show rheumatoid arthritis drugs can effectively reduce symptoms of anemia and that drugs which stimulate red blood cell production can reduce certain symptoms of rheumatoid arthritis, including pain and swollen joints.5-7 One study found that in certain patients, combined treatment of iron and a red blood cell–stimulating drug improved quality of life, increased muscle strength, and decreased fatigue.8 Close communication with your doctor will help him or her provide the treatment that is best for you based on what is causing the anemia.
*Normal Lab Values: Normal hemoglobin >12 g/dL for women, >13 g/dL for men; normal hematocrit >36% for women, >39% for men
