Causes of Arthritis
Hemorrhagic ArthritisHemorrhagic arthritis is caused by blood getting into the joint and causing inflammation. Several conditions that can lead to hemorrhagic arthritis include:
- Hemophilia, including hemophilia A and hemophilia B
- Sickle cell anemia
- Pigmented villonodular synovitis.
Are These Arthritis Causes -- Or Risk Factors?
Certain factors have been shown to be associated with a greater risk of arthritis. These factors do not guarantee that a person will develop arthritis -- they just increase the chances of developing arthritis. The more risk factors a person has, the greater his or her risk.
While some of these arthritis risk factors are modifiable, others are not.
Non-modifiable Risk Factors
- Age: The risk of developing most types of arthritis increases with age.
- Gender: Most types of arthritis are more common in women; 60 percent of all people with arthritis are women. Gout, however, is more common in men.
- Genetics: Specific genes are associated with a higher risk of certain types of arthritis, such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE or lupus for short).
Modifiable Risk Factors
- Being Overweight or Obese: Excess weight can contribute to both the onset and progression of knee osteoarthritis (see BMI Calculator to find your ideal weight).
- Joint Injuries: Damage to a joint can contribute to the development of osteoarthritis in that joint.
- Infection: Many germs can infect joints and potentially cause the development of various forms of arthritis.
- Occupation: Certain occupations involving repetitive knee bending are associated with osteoarthritis of the knee.
