I too had the Nissen procedure performed May 5, 2022. The surgeon did a full 100% wrap of the hiatel hernia and told me I would not have acid reflux anymore and should be able to eat normally in 4 weeks or so. He did remind me that with my advanced age, (83) the healing process would be considerably slower because it takes longer for inflammation to subside. Five days after the 1st procedure, I had so much pain they went back in with plans to cut the stiches to open the wrap to 75% which they couldn't do because of the inflammation obscuring their view and they weren't able to see it, so, they inserted a G-tube out of my stomach which I had in for 131 days. EVERYTHING I had for nourishment and water had to be fed thru the tube. Since the tube removal on the 31st of August, I still am struggling with eating and the overfull feeling and periodically acid reflux during the night. (I have the head of my bed raised 8-9 inches which does help some) Time is slowly helping me to eat and drink a little better every day, but I doubt if I will ever be 100%. That said, I have opted out of having a reversal of the Nissen Fundoplication because I just don't want to go thru all of this again and then not be able to sleep because of increased acid reflux. I guess patience is the key word. Good Luck!
