why does drinking coffee make me dookie?!

Best Answer - Chosen by Voters

caffiene is a diuretic

From wisegeek

Coffee and other caffeinated drinks, such as certain types of tea and soda, can cause diarrhea. The reason is because caffeine can cause contractions in the large intestine. Consuming a lot of caffeine each day can commonly cause this problem. According to Rice University, this problem is known to affect athletes, but it can really affect anyone.

Another one of the concerns with coffee is that it is highly acidic. People who suffer from acid reflux disease may find that coffee is a trigger for them. It commonly causes nausea and vomiting for them. Irritable bowel syndrome (IBS) sufferers may experience nausea, vomiting, and diarrhea due to coffee consumption. If you suffer from stomach ulcers, you may also find that coffee is an irritant for you.

I feel ya! It happens to me every time I drink coffee in the morning. Usually it only happens if I drink it too fast, or I let it sit and get cooled down after being hot.

"Coffee is said to prevent constipation. While coffee is known to be a laxative in this capacity, it can also produce excessively loose bowel movements which could lead to diarrhea."
