Why do our stomachs sometimes rumble?

Filled under:






 If sometimes has passed since our most recent meal, the stomach is empty or, to be more precise, it contains only gastric juices and swallowed air. The otherwise silent, slow and regular contractions of the stomach walls become stronger and produce a gurgling sound. However, these hunger contractions subside as soon as we eat something. The intestines can produce similar noise when the food pulp and gas it contains are being moved steadily down its length.
