Gut

Gurgly gut
Gurgles in the gut mean you need to move more. Just read in a clickbait article search result (didn't even click it) that "the more you move, the quieter your gut will be". Gurgling gut? Try doing some yoga or something.

But in my opinion milk will also cause this in me. Maybe the lactose, because I didn't have a gurgling gut when I was only drinking lactose-free milk and not eating much (if any) other dairy.
