How does obesity affect the pain of osteoarthritis (OA)? It may sound like a simple question, but this article reports on a study that sought to determine whether patients with a higher body mass index (BMI), a measure of weight in relation to height, experienced greater pain than their less-obese friends and neighbors who also suffered with osteoarthritis.
Some key points:
- The heavier you are, the more likely you are to develop osteoarthritis.
- Osteoarthritis is not necessarily more prevalent today than it has been in the past.
- Patients with a higher BMI reported more pain, regardless of the severity of their joint damage.
- For each level of arthritis severity, pain scores were higher among obese patients than among non-obese patients.
- Hormones associated with obesity may affect the severity of knee arthritis and pain.
- A decrease in body weight could decrease arthritis pain.
