Answer
Yes, obesity can cause knee pain because excess body weight places continuous mechanical stress on the knee joints. Since the knees are primary weight-bearing joints, increased load accelerates cartilage wear and joint degeneration over time.
1. Increased Joint Pressure
Every extra kilogram of body weight adds several times more force on the knees during walking, stair climbing, and standing, leading to faster joint strain.
2. Risk of Osteoarthritis
Obesity is one of the strongest risk factors for knee osteoarthritis, as excess load gradually damages protective cartilage.
3. Inflammatory Effect
Fat tissue releases inflammatory chemicals that can worsen joint inflammation and pain, even without major injury.
4. Reduced Mobility Cycle
Pain caused by obesity often reduces activity levels, weakening muscles and further increasing knee stress and stiffness.
