Sometimes your body decides that it needs to get rid of whatever is in your bowels NOW. It can be due to illness. It can be due to physical distress such as bloating or irritation. Whatever the reason your body can and will trigger the muscles in your intestines/colon to go in to emergency evacuation mode. Normally when you digest food it takes time and the body can slowly draw the moisture out. The reason diarhhea is more liquid is because there wasn’t enough time for that to happen plus the body may be releasing extra liquid in to your digestive track to help facilitate the evacuation of your bowels. Thats why its a good idea to rehydrate, your body has just wasted a bunch of water it normally wouldn’t.
