Band obstruction
At my surgery the doctor placed a primer fill in my band... the next day I drank the liquid shake they give you at the hospital and it wouldn't go down easily .. they released me and I went home and started to sip water and it would come back up.. it was vomitting it just would come right back out.. I called my doctors office they had me come back into the office as an emergency and they removed the primer fill.. they were a little unhappy the hospital released me because the test is drinking the small amount of protein shake .. Anyways you need to call the doctor ASAP.
Alot of doctors place a primer fill and some are more sensitive than others and the stomach because swollen so that primer fill needs to be removed. Even now when I get a regular fill at the doctors office I get very swollen and have to be on liquids for two days...
Good Luck
