When I saw my surgeon on Day 6 post-op, he informed me that my wrap would become increasingly more swollen over time, peaking at approximately two weeks or so, with some variation. This swelling generally begins going down at some point after it peaks. How fast the swelling reduction occurs, is an individual and unique experience. Every body heals in its own sweet time.
I assume you can't burp at all, so whatever you're eating that produces gas can't escape out the hatch, but must wait until it goes through your whole digestive tract, and that's not fast enough to avoid painful bloating.
The wrap creates a flap that covers the entrance of the esophagus, to keep stomach contents where it belongs. Very often, the wrap will be able to open enough to let some of the excess gas out, which helps protect from paintful bloating. Swelling can interfere with this. (I expect that your GI doc is waiting for the swelling to subside.) Also, a tight wrap can relax a bit with time...making it easier for air to escape. When your stomach gets too full with food/liquid/gas, it presses against the wrap/flap, and won't allow the escape of gas. The result is painful bloat.
I assume with your bloating issues you're remembering to stay away from gassy foods. Each person's trigger foods are unique. Some people can eat one thing without a problem, while that same food can trigger terrible gas in another. Here's a list of possible gas producing foods I found online. When I read it, I wondered what it left for us to eat?!! I would think it would be trial and error.
Milk and dairy products
Starchy foods like potatoes and pasta
Wheat and oat bran
Foods sweetened with artificial sweeteners, such as soda, gum, and hard candy
Bananas, peaches, apricots, pears, and raw apples
Raisins and melons
Prunes and prune juice
Colas and fruit drinks sweetened with fructose
Beans and lentils
Onions, green peppers, shallots, and scallions
Cauliflower, broccoli, Brussels sprouts, and peas
Corn, celery, artichokes, asparagus, and carrots
Of course, carbonated beverages and straws are out. They both cause increased gas. I found BEANO (about three chewable tablets immediately before eating veggies that can cause gas) to be helpful. I used it a lot during my recovery, and only very occasionally now (5 and a half years post-op).
I know bloating is uncomfortable and can be painful as well. It is hard to wait for your body to heal enough to resolve your problem. I wish there was a shortcut to healing, but there isn't. It can be frustrating and hard to trust that you will ever overcome the problem, but you will! It's likely that it will be one of those quirks that takes it's time to go away, but go away it will.
Hang in there!
