Why is diarrhea preceded with a physical ‘rumbling’ in one’s body, often to the point of being audible?

Question

I know that diarrhea is when the intestines don’t absorb enough water back out of one’s food, but how is this related to the ‘rumbling’ you experience, both in terms of feeling your body do that and the fact it happens loud enough to be heard?

Answer 1

It’s called peristalsis, and it’s your gastrointestinal muscles moving waste and gas down toward your anal sphincter. It’s the exact same mechanism and sound that occurs when you’re very hungry and you hear/feel your stomach rumbling.
