Weight Loss Eases Back Pain
Low-back pain and sciatica are common among obese patients. Research shows that having a high BMI can slow your rate of recovery from low-back pain and increase your risk of common causes of sciatica like lumbar disc degeneration. 2-3 Decreased space between the spinal discs can lead to nerve impingement and sciatic pain.
This new study included 30 morbidly obese patients who had undergone bariatric surgery. 4 As patients lost weight, the space between the discs in the lumbar spine increased, easing pressure on irritated nerves. Patients also experienced a significant reduction in low-back pain and radiating leg pain.
For patients concerned with the potential costs and risk of surgery, non-invasive weight loss could be a viable option. A 2012 literature review concluded that exercise and physical therapy can significantly reduce back pain in obese patients without the risks of surgery. 5 Weight loss has also been shown to relieve knee pain in obese patients.
