Before she was diagnosed, my daughter's gurgling could be heard across the room. A pediatrician suggested, while she was on an antibiotic for a bacterial infection, that she take yogurt.
The yogurt dramatically reduced the gurgling (yes, it did turn out to be a stricture). Then, once she was diagnosed, we found out about the SCD diet and made our own yogurt. She is in college, living in the dorms, but faithfully makes her own yogurt.
I'm having that exact same problem with noise. Losts of gurgling and at times it can keep me awake at night. Mine is due to a stricture which today im going into hospital to have a operation ( Resection ).
Don't worry to much about the noise because I can say I've had that going on for a few years. But with the added feeling its really uncomfortable enough is enough.
I wish you well.
