Nissen Fundoplication Complications/Questions

Welcome to the forum.

Sorry your fiance is having pain. I would recommend he see his surgeon or gastroenterologist.

Pain might be just gas, or just the constipation, or it might be something that needs to be checked out. Gas can build up because most of can't burp for a while after the surgery. I had gas pain for at least 6 months. Eventually it eased up and went away. My treatment for it was to eat only non-gassy foods (see google).

If he can look through his journal and identify at least a few of the foods that seem to always cause pain, then he can google them adding the words food allergy or food intolerance. That's how I came up with my food triggers. It took me several months of keeping my diary/journal/log and even then I kept finding more foods. I started in 2007 and even this year have added a couple of foods. Fortunately for me my trigger not like peanut allergy, where a tiny bite can cause a reaction. I have to consume a moderate amount. But each person reacts differently, and to different triggers.

For constipation I use a half capful of Miralax (the generic is cheaper) in my morning coffee. There are many other products. I wouldn't recommend the products that cause gas, like some of the fibers. Wheat dextrin is OK. Some people take docusate stool softener. I react to the sulfite in it. Constipation can cause chest pain because the colon runs up and across the abdomen and it seems like it's in the chest.
