Yes, it is possible.  However, keep in mind that there will be only a small gastric remnant if a sleeve has already been performed, as opposed to having a large gastric remnant with a gastric bypass is performed as the initial operation.  Without a gastric remnant, should problems arise with the gastric bypass, the options for solving the problem are more limited without having a large gastric remnant.

These symptoms are more than we would expect two months out. I would recommend that you call your surgeon's office and schedule an appointment to further evaluate this issue. 

StomaphyX is mostly off the market as it was not that effective. It has been replaced by the Apollo endosurgical procedure. This is a way to reduce the size of the stoma or opening from the gastric pouch. There is another method called Sclerotherapy that uses an injection by scope to shrink the stoma. What revision you need depends on what is wrong. Some of these new techniques are not covered by insurance. Call me if you have any questions, or you can can call the office for appointment if you want.
