Bad cramps before I go to the bathroom? Help..?

If you find it hard to do # 2 it could be constipation. If the 2 is loose than you have the runs. Either one can be cause by things you eat or drink. If it's do to things you eat and drink, changing your eating habits will make it go away. How to know if it's do to that is, if the problem only happens when you eat or drink certain things that day.
