title: [Evolution of low back pain after bariatric surgery].
abstract: Although frequently called to mind by physicians, the relationship between overweight and low back pain is poorly understood and remains controversial. The present study aims to evaluate the evolution of low back pain in 65 patients planned for a bariatric surgery. The patients were enrolled prospectively. 54 patients (80%) could be evaluated 5 months after the procedure, and 47 patients (72%) were evaluated 22 months after surgery. Mean weight loss was 19 ± 9 kg (P < 0.001) at 22 months post-op. Patients demonstrated a statistically significant improvement of the NRS, Oswestry and SF-36 scores. This study suggests that low back pain might be reduced following bariatric surgery. However, the lack of dose-response effect is against a causal relationship between low back pain and obesity. Larger randomised controls are needed to determine a causal relationship.
