Does caffeine make you constipated

I think it has a bad effect on your digestive system. :( I'm a coffee drinker and I recently stopped drinking coffee because I have been badly constipated, I think being off of coffee has helped a lot. I read a lot of articles on WebMD, and all of them say to stay away from caffeine, they don't say why, but coffee most likely does not help constipation rather makes it worse. I'm sure though if you drink plenty of water, eat the right foods with plenty of fiber, and exercise you can get by with drinking coffee.
