July 24, 201115 yr If your band has slipped, you will struggle to keep liquids down and any food will come back up. Not sure it is painful so much as just constantly being sick as there is no room in the bottom pouch for anything, If this is the case, get to A&E right away, you might be able to have it resited or it will be removed.
How do you know if there is slippage? Is it painful?
