Osteoarthritis
What is it:
Osteoarthritis is a type of arthritis that is caused by the breakdown and eventual loss of the cartilage of one or more joints. Cartilage is a protein substance that serves as a "cushion" between the bones of the joints.
Who has it:
27 Million Americans.
Osteoarthritis affects 13.9% of adults aged 25 and older and 33.6% of those 65+.
Obesity increases the risk for osteoarthritis of the knee and hip. Obesity causes osteoarthritis by increasing the mechanical stress on the cartilage. Next to aging, obesity is the most powerful risk factor for osteoarthritis of the knees.
Consequences:
Osteoarthritis accounts for 25% of visits to primary care physicians and half of all NSAID (Non-Steroidal Anti-Inflammatory Drugs) prescriptions. If the medical management is ineffective, joint replacement surgery may be required. Individuals with very painful osteoarthritis may require surgery such as fragment removal, repositioning bones, or fusing bone to increase stability and reduce pain. Maintaining ideal weight, or losing excess weight, may help prevent osteoarthritis of the knee and hip or decrease the rate of progression once osteoarthritis is established.
