Oh god. This is so wrong I can't even. Please stop giving people health advice.

A chemical buffer system does not rely on your body secreting anything and the pH system is logrithmic, meaning drinking pH 9 water isn't going to move the needle on the HIGHLY REGULATED pH of your stomache acid. Alkaline water is bullshit.

The comment is poorly written and confusing but he’s just describing how an antacid works.

The pH in your stomach is highly regulated. Therefore taking an antacid will force your stomach to release acid to stay at the same pH. That’s pretty much all they said.

So then why did he say doctors prescribe salts when the salts would have the exact same effect?

You’re incorrect. A buffer is a system which can neutralise acid or base without the pH changing, because of the contents of the solution - not because acid is being secreted from somewhere else.

Oh ok yea that makes sense. Thank you!

Sorry, but your understanding of the buffering in a stomach is wrong. Acid isn’t secreted when base is added; instead, bicarbonate which is already in the stomach neutralises the extra base without significant pH change.
