My experience differs with the other answers to this question based on my experience. Basically, your individual situation will dictate what the best course of action will be.-Your abdomen will be tighter after surgery and this can increase the feeling of fullness and restriction from your band. If you are currently "tight" or have any history of getting things like bread or meat "stuck" then I suggest emptying the band.-You may develop nausea or vomiting after surgery from the anesthesia or pain meds. This can be a problem and cause swelling of the stomach around the band. I have seen this issue several times and it can take a while to settle down.-You will need increased calories after surgery to promote healing, especially if you are considering a more extensive procedure. A tight band can interfere with you getting your nutrition in, plus the meds you will be taking.-Interestingly, when I have emptied bands there is often less fill than the bariatric surgeon or patient believed. Probably because of slow leakage of saline or a "miss" during the fill procedure. Unfill gets you a chance to reset your adjustments.Tummy tuck is also a chance to reseat the port, as it often becomes loose after weight loss.BestDr L
