The gastro-colic reflex is one of those medical phrases that sounds more important than it is. Roughly, it means: when the stomach fills, the colon wakes up. For many people, coffee — particularly on an empty stomach — triggers the same response.
This is not universal. It is not a disorder. It is a variation. In our product data, roughly 38% of users who log patterns at all have some form of this one, with a noticeable family pattern on the maternal side.
Why does it matter? Because knowing it means you can plan the morning. It means you don't avoid coffee; you avoid coffee on empty. It means when your daughter starts drinking coffee at sixteen, you can tell her: "This runs on my side. Expect the bathroom about fifteen minutes after, if you don't eat first."
That sentence is what DB.Life is for.
