Answer 1

Typically, no. The environment in the stomach is far too hostile to yeast to allow for the time required to ferment.

That said, there is a condition known as Auto-brewery syndrome where the stomach does not kill off the yeast fast enough and they _do_ ferment some of the sugars, producing alcohol.
