Does a beer belly cause back pain?
Beer belly, pot belly or belly fat can and does cause back pain with some people. This is because the excess weight, especially in the belly, strains the back muscles and ligaments resulting to a periodically back pain as a result of the back pulling out of normal alignment when we gain extra weight.
Our normal posture is meant to be upright with our chest out, stomach tucked in and our lower back keeping our hips straight. With weight gained, every part of our body becomes heavier leaving our spine to bear the burden of the weight. This is another way which weight gained can cause back pain.
