Is it normal to poop not long after eating?
Yep.Totally normal
Yes, it’s normal to need to poop soon after eating. A meal can trigger your gut to move along stool that was already there; the food you just ate isn’t passing straight through you.
Your gut has a built-in “make room” response called the gastrocolic reflex: when your stomach fills, it can prompt your colon to move. So needing the bathroom after a meal—often breakfast—is common, and people’s timing varies.
