This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is following people who have weight loss surgery to see how losing a significant amount of weight affects back pain. Researchers will use imaging tests like MRI scans to look at changes in the spine and fatty tissue buildup that may compress nerves and cause pain. The goal is to understand which patients benefit most from weight loss surgery in terms of back pain relief.
Many people with obesity experience back pain, and doctors have noticed that even after weight loss surgery, some patients still have back and leg pain. This study exists to figure out exactly what happens to the spine and nerves when weight drops significantly, and to identify what factors determine whether pain gets better or stays the same.

As a participant, you would visit the hospital at set intervals over one year following your weight loss surgery. At each visit, researchers will ask you about your back pain, perform physical exams, and take imaging scans (X-rays and MRI) to measure changes in your spine alignment and nerve compression. The study team will track your weight loss progress and correlate it with any changes in your pain symptoms.
