Glad to say that I am now >10 years post Nissen and I'm still going strong
I had my Op in the North East of England back in October 2003 when I was aged 35.
Haven't had heartburn (apart from a small occurrence lasting a few days when I had shingles - any lurking medical students want to try to explain that one???) or a single PPI in all that time and still have no problems to report.
Had a "tight" wrap so still can't burp or vomit, but to be honest I really don't notice this as an issue anymore and just eat and drink what I like when I like - though I still chew more but I don't have to think about this anymore, I just do it subconsciously.
I do have to take an occasional ant-acid or wind-eze (gas-x in the uk) if I over eat, but that's no different to anyone else who hasn't had the Op.
Thought I'd post a positive story to give hope to anyone suffering as I was back then and worrying about the risks that there are a lot of success stories out there too (and the success rate is way higher now than it was 10 years ago!).
Here's to the next 10 years of looking forward to Christmas dinner and not worrying about the after effects.
All the best.
