The more weight obese and overweight individuals lose, the better it could be for their knee joints, new research suggests.
Being overweight or obese can place extra pressure on joints and cartilage, causing them to wear away. In addition, people with more body fat may have higher blood levels of substances that cause inflammation in the joints, raising the risk for osteoarthritis.
“For this research, we analysed the differences between groups with and without weight loss,” said the study’s lead author Alexandra Gersing from the University of California, San Francisco, US.
“We looked at the degeneration of all knee joint structures, such as menisci, articular cartilage and bone marrow,” Gersing said.
