Is it vomiting?

It's an acronym for "Productive Burp" which is what many call it when, once you have restriction, you take a bite of food that is too large or not well chewed or for whatever reason will not go through a lap band stoma and on into the stomach below. Not strictly traditional "vomiting" (because there is no stomach acid etc) the term was coined to describe that specific type situation. It is usually accompanied by excessive mucous production which is referred to as "slime". You can "slime" without "PB'ing", because sometimes the food goes on through. It is not comfortable and is a good motivator to chew chew chew and take small bites. A few people will PB anyway but usually it is because of the reasons I've listed, or because the band is filled too tightly.

Terrific answer--very clear and comprehensive--thanks!!!

You are very welcome! Nice to know I'm coherent this late on a Sunday night!

for me when i hear the words "productive burp".... burping is not what happens for me even though i know i'm PB'ing.

i can feel the food lodged right under the breast bone. it's a lump that won't go away... and it hurts.

i stand and lean from the waist over the toilet, cough twice and the piece of stuck food comes right out.

usually if i'm burping that tells me the food is going down okay.

Same most of the time I will have the slimy burps or just a reguritate slightly as the stomach is trying to move the lodged food. If after about 30 minutes of this excruciating sensation it wont move I then generally will throw it up (only what was stuck in the stoma). However my doctor said that projectile vomitting is very bad and can cause band slippage so I generally try very hard to avoid the throwing up.

I am four weeks out from surgery and go for my first fill on Friday (2 days). There are times I can eat a "normal" size meal - so I don't think I'm too tight and probably need a fill. Other times, I take one or two bites and PB/vomit cups of slime. Doesn't seem to matter what I'm eating - once something hits all that mucus - up it comes.

Have lost 25# including during the pre-op diet but no weight loss in two weeks. Sound normal/ok??
