I recently had the Nissen Fundo for my 13 year battle with reflux, and the Barrett's Esophagus that surfaced over the past couple years. Had the surgery 6 weeks ago. Prior to the surgery I spoke to 4 people personally that had the surgery. 2 of them, one a doctor friend of mine, said that they did low carb first and really found relief. One decided to go ahead with the surgery because esophagus cancer runs in his family and he wanted the added extra protection. He still swears by the low carb, as does the doctor.
I still decided to have the surgery due to Barrett's and the fact that meds were just not doing the trick. Also, I can only do low carb for so long - life long constipation and low carb always makes mine worse. At the 6 week point I am having reflux symptoms, so I purchased a book recently regarding low carb eating for GERD. I see my surgeon again in a couple weeks, but I figure it cannot hurt to give the diet a try. I think it is by Dr. Norm? Can't remember. I am waiting on it to arrive. Good luck!!
