What Causes Constant Gurgling Sound In Chest?

I have never burped, at least never in my adolescent and adult life. I ve asked my parents about when I was a baby but they couldn t give me a definite answer. Anyway, instead of burping, I get these gurgling, growling noises in my chest and throat. I can t stop them, quiet them, or avoid them (by not eating certain foods, etc...). I have searched for similar cases but have not found any. I am hoping someone can help me or at the very least, someone is somewhat familiar with this situation. Thank you for your time.
