Depends. Not that I am aware of; most patients experience some adjustment to there new way of eating; and some post-op scarring but i would expect as weight loss occurs that back pains resolve. Best to as this question to those who have undergone the procedure; or to those who perform the procedure routinely. If i hear anything different i'll 're-tap'. Cheers!
Usually better back. Most patients have much improved back symptoms. However, a herniated disc will usually remain a problem. In many cases, a surgically correctable cause for back pain becomes more reasonable after the weight loss.
