When asked what health problems are directly attributed to obesity, the most common answers are hypertension, heart health, and diabetes, but obesity has a large affect on another condition – arthritis.
One out of five Americans has been diagnosed with arthritis, but according to the Centers for Disease Control and Prevention (CDC), that number nearly doubles among those considered obese. Obesity not only raises the risk of getting a certain type of arthritis; but for those who already have arthritis, obesity makes the condition worse.
Here’s a look at what fat does to arthritis, as well as some tips to put you on the road to losing weight.
Osteoarthritis (OA) is the most common type of arthritis, affecting approximately 27 million Americans. It is characterized by the breakdown of cartilage – the flexible but tough connective tissue that covers the ends of bones at joints. Age, injury, heredity and lifestyle factors all affect the risk of OA.
OA has a logical link to obesity: The more weight that’s placed on a joint, the more stressed the joint becomes, and the more likely it will wear down and be damaged.
Every pound of excess weight exerts about 4 pounds of extra pressure on the knees. So a person who is 10 pounds overweight has 40 pounds of extra pressure on his knees. If a person is 100 pounds overweight, that is 400 pounds of extra pressure on the knees, causing those who are overweight to be at greater risk of developing arthritis in the first place. Once a person has arthritis, the additional weight causes even more problems on already damaged joints.
