A member asked:

How long after a meal does it take to for the stomach to return to it's original ph before you put nutrition into it?

A doctor has provided 1 answer

Around 4 hr: Normal stomach emptying after a meal is about 4 hours to completely empty. Since food buffers acid, i would expect the ph to drop back down to 1-2 within 4 hr.
