Thinking... Is it a gas-powered boat?

I'm really worried about the gas buildup in my stomach.

Sometimes, even without eating a lot, I feel bloated and my stomach feels full.

If it's because you ate a lot, you wouldn't even feel upset!

Sometimes, without any reason, my stomach becomes bloated to the point that it interferes with my daily life.

Will I get gas if I drink a lot of coffee?

I'm wondering if not drinking enough water also has an effect.
