I pushed hard on my upper abdomen when i heard a loud sound of air (moving / escaping) i then had a lot of stomach gurgling noises and alot of burping. what could this mean? what happened?

Gut flora: Depending on the diet, individuals may experience periods of gassiness where imbalanced gut flora are producing more gas due to increased fiber or other undigestibles. The gas is freely moveable within the intestines and can be expelled through the esophagus (burp) or anus (flatulence). Try taking a probiotic to help with balancing your gut flora.
