Hi Sam,That is definitely a world-class DeMeester score, so I'm not a bit surprised that you're scheduled for surgery. If GERD is your only troublesome symptom, you will find a new lease on life once you've made it through your early recovery period. You'll look back at your pre-Nissen life and wonder how you managed, and why you didn't get the surgery sooner!
It is important to select a surgeon who is highly experienced in doing the Nissen procedure. If you've done that, you're good to go, and can expect a great outcome.
Here's a link to my early recovery journal. It provides a glimpse into one person's recovery experience. I had lung issues caused by reflux (and asthma/allergies), so disregard the references to those.
