Overseas medical insurance customers might want to keep an eye on their weight as a side effect of obesity has been highlighted.
Research presented at the Annual Meeting of the American Academy of Orthopaedic Surgeons showed that obesity contributes to additional complication and pain from knee osteoarthritis.
Indeed, even after losing weight, patients were shown to be struggling with knee problems, suggesting that the damage done could be permanent.
Following the study, professor Alan Silman, medical director of the medical research charity Arthritis Research UK, remarked upon the fact that overweight people are usually advised to lose weight before they undergo surgery on their joints.
"Joint replacements in obese people were ten times more likely to fail after seven years, compared to replacement rates in people of healthy weight," the healthcare expert explained.
