The reality is that the posts you're going to see on this forum about complications from the surgery are a very small minority of cases. So many people get the surgery and move on with their lives, and don't even think twice to come back and post about their results, or share them.
With respect, I would disagree with this.
The Nissen is major surgery that takes a long time to recover from. The first few months are like a rollercoaster ride and you get a lot of severe and misleading symptoms (including reflux) that convince you the surgery has failed.
People seek help as most surgeons seem incapable of telling the patient up front what the journey will be like. Instead we have to find out for ourselves and seek help and information from support groups like this.
Maybe surgeons don't tell their patients the severity of the surgery as "a positive frame of mind aids recovery" - well this fails when months later you still wake up with chronic reflux, cannot eat, miss work as you cannot stand up straight, and have pain from your chest to your groin.No doubt it is a serious, involved surgery that entails a long, trying healing process. That said, I still feel it's disingenuous to imply that complications or poor outcomes are anything but a small minority of cases.
Months or years later people may be glad they had the surgery and celebrate having no or reduced reflux, but I don't hear of people who have this surgery and just "move on with their lives". It is major surgery and your body will react appropriately.
Of course you don't hear of them - they aren't posting to message boards about
their problems because they're out living their lives instead. I have many chronic illnesses, and a great deal of experience with illness-specific forums. It's incredibly important to remember that most of the complications and negative outcomes you will see in forums are the minority of patients whose problems are so difficult or trying that they seek out assistance or information from others. It's a confirmation bias.
It is important to understand what will happen, and what can go wrong - but I think it's wrong to ignore the many, many majority of patients that are successful with no major complications.
