Are you one of the many people who find that once they start doing some exercise, particularly vigorous stuff like running, you get a sudden urge to open your bowels? More often than not it’s a runny motion too. Why does exercise give you diarrhoea? Is there such a thing as exercise-induced poop? It’s so annoying, can be really inconvenient (think crouching in the bushes) and actually put you off being active in the first place. It’s a very common problem so I thought I’d answer it for my #QuickQuestion this week.
