Welcome to the
At six months post op, you could definitely be getting irritation. While probably 80% or so of healing has occurred, you've got more healing and adjusting to do. It's way too soon to panic over your wrap failing!
Many people take a full year or more to put their "quirks" and discomforts behind them. Around here we tell people it takes a full six months for most of the healing, and a year for the rest. It's pretty much the standard for any surgery. I had intermittent dumping throughout the first year, and figured I'd always be dealing with it, but sometime during the second year, it disappeared.
Certain foods can irritate the wrap/base of esophagus, and create reflux-like symptoms. I couldn't eat entree salads or many raw veggies during my first year or two. It always irritated my wrap and made it uncomfortable. I found Carafate suspension helped when I irritated my wrap, and made it more comfortable as it healed.
In addition, keep in mind that you can get reflux even after the Nissen surgery. There are still some triggers that can cause stomach flares, and some reflux. Surgeons don't go for zero reflux, or you wouldn't be able to get food through the wrap and into your stomach. Rather, their goal is go get reflux down to "normal" levels...the type that most people get occasionally. It's a possibility that you got a little reflux and irritated things, so they have to calm down and heal. Your stomach/wrap/esophagus have been through a lot. It is a big adjustment, so little problems can be more painful.
I remember getting fairly frequent irritation during the first year or so. I'm five years post op now, and I can eat pretty much anything without a problem. Still, it's possible to get an occasional irritation even now. The wrap is an unnatural barrier, and food has to push through. It's always important to take smaller bites and chew, chew, chewing your food thoroughly. Even 5 years post-op, if I don't, I can get food held up at the wrap site a bit.
Try to be patient. Remember what it was like before your surgery! Be sure to be very easy on your wrap for a while, until it gets feeling better. Make sure that you stay away from spicy, acidic foods, rough foods that don't chew to a liquid/creamy consistency, and alcohol, until you get things feeling better. It will take time to get it healed, but it will get better. You'll have some ups and downs as you get through all this, but if you can keep a positive attitude, and try to be patient, you'll do fine. Don't panic. It will all work out!Happy healing!
