Osteoarthritis

Osteoarthritis causes joint pain and stiffness. Every extra kilogram of body weight puts 4 kilograms of pressure on your knees. Weight loss is one of the most effective treatments for reducing joint pain.

OA is characterised by progressive cartilage loss, subchondral bone changes, and synovial inflammation. Obesity is the strongest modifiable risk factor, with each unit increase in BMI above normal increasing knee OA risk by 35%.

Weight loss of 10% can reduce knee pain by 50% and delay or avoid the need for joint replacement surgery.
