Hi mello!I can't remember if I already did this, but just in case I haven't, welcome to the Healing Well
Wrapped Club!
Alcie's suggestion that you call your surgeon is a good one. It's possible that you might just be told to listen to your body.
If you're one who tends to eat too much, then regret it because it creates discomfort, I'd suggest that you continue to measure your food intake, but just increase it gradually until you reach a point where you're at a comfortable level.
I didn't actually do any measuring. Instead I ate very slowly, took small bites, and chew, chew, chewed my food until it was a liquid consistency. Eating slowly allowed my brain to receive the "full" signal in plenty of time to avoid over-stuffing.
You are right to be aware of the fact that you don't want to over fill your stomach and put undue pressure on your healing wrap. You can have some real discomfort if you do, and it takes time for it to empty enough to find relief.
After a Nissen you'll always want to eat more slowly, and chew your food more carefully. You've had an unnatural barrier constructed to keep your stomach contents where they belong. You're used to eating with a much too relaxed LES, which is why you needed the surgery. You'll have to get used to the resistance your new wrap will present.
The possibility of bloating is also increased--especially during recovery. Sometimes your fullness is related to gas that can't escape up the esophagus any more. Be sure to watch your eating of gassy foods. I found BEANO helpful with vegetable gas. I chewed three tablets just before eating things that are known gas-producers.
Good luck finding that perfect balance! You can do this!
Happy healing,
Denise
