Hey, Dr. Ken Brown here.

If stores seem to trigger your gut, here’s why it can happen.

Your colon has a reflex called the gastrocolic reflex. Basically, your gut can start moving when your body gets signals like food, movement, stimulation, or stress. Research also shows this reflex can be stronger in people with IBS or sensitive guts.

So when you walk into a big store, you may be stacking triggers: walking, bright lights, cold air, stimulation, maybe coffee or food beforehand, and a little “where’s the bathroom?” anxiety.

That’s the perfect setup for urgency.

Here’s how to control it:

Use the bathroom before you go in.

Be careful with coffee, greasy food, carbonated drinks, or big meals before shopping.

When the urge hits, slow your breathing and don’t panic; stress can make the gut louder.

And if this happens often with cramping, diarrhea, bloating, or sudden urgency, start tracking it. Your gut may be overreacting to normal triggers.

The goal is simple: know your triggers before your colon chooses aisle seven.
