Which part of the digestive system is most acidic?

Mouth🤪, If it is bad see a doctor, maybe for Omeprazol or ranitidine.

Mouth🤪, as we get older, stuff wears out! smile.Try mints, not gum, chewable type. sitting up in bed.

Mouth🤪, yeah, me too! as far as I can tell it is because the valve between your osephagus and stomach doesn't really close properly.

I have acid reflux a lot since I got my thyroid removed that is.

Player #53553731, FYI ... The human stomach does not "grind" our food; however, it does "mix" and "churn" it. The organ that "grinds" food is called a gizzard, which humans do not have.
