When you are constipated it is like a dam, when the dam gets unblocked there can be a lot of feces in you needing to come out. Especially if you use laxatives.

Hi. I have the same issue. It was diagnosed as IBS with constipation. I would be stuck fo fourvor five days then a potty jogger for 2 days. When it broke free, the pain would be so bad I would vomit.
Although Celiac disease was ruled out, the symptoms have lessened in intensity from laying off breads, dairy, and soda and a big let up in caffiene.
I hope you feel better soon.
