I have lost a little over 50 pounds and had the band since Dec so I should not be asking this totally newbie question BUT, in the beginning, I did A LOT of PB, only needed one fill (which was sort of aggressive and I had to go back to take some out). I didn't tell the dr I was having a lot of PB but now, I realize, that is why I needed so little fill to get restriction. I think. Now I am finding I have little restriction (back to post op level) Could it be that it took about a month of careful eating (so I have no pb at all) to reduce all the swelling? I only have about 2.5 cc now. Is that what happened or is something else going on?

That is quite possible what has happened. When you were constantly pbing your stomach remained irritated and swollen. As you stopped, your swelling went down. Now that you are pb-free, you may want to consider a small fill. Take it slow, and I am sure you will not hesitate to return if it is too tight. Good luck

As you lose weight the fat pad around your stomach is also losing fat thus making your band looser. Every two months or so I would go from the perfect restriction to needing a little top off.

Wow! I recently lost some weight (FINALLY) from around my middle. That is interesting. I also didn't think of my stomach swelling. I was thinking more esophagus. Thanks all!
