all organs grow when you grow up - but stomach has ability to shrink and expand depending on how much you eat, how big are your portions. (e.g anorexics have stomach in size of a small fist)

A lot of people seem to get a bigger gut as they age because their activity level decreases and their food intake remains the same.

It does not get bigger, just more elastic. You can stretch it more because you lose more muscle around your stomach as you get older.

It gets bigger because we sit around more and we don't burn many of the calories that we take in.

your stomach distends. with time, the muscles weaken and become longer, and everything sags.....its scary and gross...

when u find out let me know.. lol
