Which embarrassing, but usually minor, medical condition is technically called "Borborygmus"?
We're all familiar with that rumbling sound, whether from ourselves or others, and know its perverse tendency to appear as if on cue in silence or a solemn situation.
It derives more immediately from the French "Borborgyme" and ultimately from the ancient Greek, where it appears to be merely onomatopoeia, proving the point that onomatopoeia does not always work well in translation!
The condition is, in most cases, not a serious one, and can be easily remedied by adapting one's diet, but in some instances, if severe, it can be a symptom of lactose intolerance, diverticulitis, or coeliac disease.
In fact, in some instances, the chronic absence of rumbling can be more potentially worrying than its presence, as it points to potential intestinal blockages.
