Answer
Yes, obesity can cause joint problems. Excess body weight places increased mechanical stress on weight-bearing joints, especially the knees, hips, and lower spine. Over time, this added pressure accelerates cartilage wear, leading to pain, stiffness, and reduced mobility.
1. Increased Joint Load
Every extra kilogram of body weight adds multiple times more force across joints during walking or climbing stairs, speeding up joint degeneration.
2. Risk of Osteoarthritis
Obesity is a major risk factor for osteoarthritis, particularly in the knees, as continuous overload damages joint cartilage.
3. Inflammation Factor
Fat tissue releases inflammatory chemicals that can worsen joint inflammation and pain, even in non-weight-bearing joints.
4. Reduced Mobility Cycle
Joint pain caused by obesity often reduces physical activity, which further weakens muscles and worsens joint stiffness and dysfunction.
