Do you sometimes suddenly have to go to the toilet halfway through your run? It's not a sexy topic of conversation, but it's not crazy at all. While running you stimulate your intestines.
The main cause is the jerking movement of your body while running. It puts pressure on your stomach and intestines. You may experience abdominal pain, or you may feel that you suddenly need to go to the toilet. The blood flow probably also plays a role in intestinal complaints while running. During running, the blood flow in the gastrointestinal tract decreases, so it can do its job less easily.
