Hi Nancy,
I too was diagnosed with Barretts about 6 months ago, I am 52 years old and had been suffering from GERD/heartburn for over 20 years. I was freaking out and depressed until I ran into this forum, I know much more about Barretts now.
I had fundoplication surgery in Sep 12 and have had no heartburn since. I am hoping that this will help my Barretts condition. I have modified my diet somewhat and with my surgery I am hopefull in combating Barretts, my surgeon does not recommend an endoscopy until 12 months after surgery.
I don't know if the surgery is an option for your husband, for me it seems to be working like a champ. Your husband may want to discuss the surgery option with his GI doctor.
