Low Back Pain and Obesity
Low back pain is more common and more disabling in people with obesity, and losing even a modest amount of weight can significantly improve it.
Plain English
Patient-Friendly Explanation
Low back pain is more common and more disabling in people with obesity, and losing even a modest amount of weight can significantly improve it. Excess weight increases the load on the lower spine, and fat tissue also promotes low-grade inflammation that can make pain worse. Losing about 5 to 10 percent of body weight is enough to reduce pain and improve mobility for many people.
Medical
Clinical Definition
Obesity is an independent risk factor for chronic low back pain, lumbar disc degeneration and related disability. Biomechanically, excess weight increases compressive and shear forces on lumbar intervertebral discs and facet joints, while visceral adiposity contributes a systemic pro-inflammatory state — with elevated cytokines such as interleukin-6 and tumour necrosis factor-alpha — that may sensitise pain pathways. Randomised and cohort evidence indicates that weight loss of approximately 5 to 10 percent, particularly when combined with exercise, produces clinically meaningful reductions in pain intensity and functional disability, and marked improvement in back pain has been reported after bariatric surgery.
Key Insight
Why It Matters
Many patients believe back pain means they should rest more, but when excess weight is a driver the opposite is often true. Safe, gradual weight loss with appropriate activity is a central part of how we approach this problem.
