Will eating too fast eventually become detrimental in any way?

I know this sounds like a no brainer but I have been eating to fast for the past 6 months, just here and there, like 5–8 times a week I will eat my meals to fast to the point where my stomach kind of hurts afterwards. But I always feel better within 20 minutes.

And so I ask, can doing this cause any long term, and I guess short term problems with my body? and if so, what?
