Yes, obesity is a risk factor for spinal stenosis, a condition that occurs when the spinal canal narrows, potentially pinching nerves. Obesity can contribute to spinal stenosis through biomechanical changes that damage the spine, such as:
Degenerative disc disease
Being overweight or obese can speed up the process of disc wear and tear, which can reduce their ability to cushion the spine.
Increased compression forces
Adiposity in the trunk of the body can increase compression forces on disc surfaces.
