Has anyone here who suffers from GERD undergone or considered Nissen fundoplication?

Here’s my journey with bb. It has been on and off for about five years. Here’s a list of what I’ve tried to find a cure:

1.Sinus surgery - I was free from bb for a maximum of two months.

2.Dentist visits - I saw four different dentists to be sure, and they all confirmed that my teeth weren’t the cause.

3.Gastroscopy + Colonoscopy - Esophageal sphincter dysfunction, no H. pylori

4.Tonsillectomy - I was free from bb for three weeks afterward.

5.Wellness Center - This place used a simplified gas chromatograph to determine the root cause, which turned out to be from my stomach, not my mouth.

6.Urea breath test - I just wanted to recheck if I have H. pylori, but the result is still negative

I still suffer from GERD, and I think it might be because my esophageal sphincters aren’t closing properly, which causes my bad breath. However, due to many disappointments, I just want to hear about others’ experiences and opinions before deciding to go through with it.
