Osteoarthritis post #5 Prevention

Can a person prevent osteoarthritis? 

We cannot change some risk factors such as our genes and our age.  We can work to keep our weight within a normal limit.  If this was easy, most of us would be there.  Millions of Americans struggle with the weight issue.  (Remember I’m a weight watcher achiever, for the third time.  See Feb 10, 2011 post.) 

However, we do need to know that every extra lb of weight adds 4 lbs of pressure to our knees and 6 lbs of pressure to our hips.  On the other side of the logic, if a person loses even 10 lbs the pressure on his hips and knees decreases and the risk of developing OA decreases.
