The form and consistency of a bowel movement is one of the most immediate, externally visible signals of how digestion is working, and it can shift within a day or two of a change in diet, hydration, or routine. Here is what the Digestive Pattern measures and how to read it.

Throne sorts every bowel movement into four plain-language bands, based on how firm or watery it is:

Over time, the mix of those bands becomes a picture of how steadily digestion is running.

Much of what determines stool consistency traces back to one thing: water. As stool moves through the colon, the colon reabsorbs water from it. How much it removes depends on how long the stool spends there — a measure called transit time.

When stool moves through quickly, the colon has less time to extract water, so it comes out looser or liquid. When it moves through slowly, more water is reabsorbed, leaving it harder and drier. Form, in other words, is largely a readout of speed, which is why a hard stool and a watery one point to opposite patterns upstream.

Throne's four bands group the Bristol Stool Form Scale, a seven-type classification developed at the University of Bristol and the most widely used clinical reference for stool form. It is relied on because form is such a dependable proxy for transit time.[1][2] Types 3 and 4 — smooth and sausage-shaped — are considered the physiological ideal, which is what Throne labels Healthy.

In everyday use, the scale's weak point is that it usually depends on people noticing, remembering, and correctly recording their own stool form, which research has shown is frequently inaccurate. Throne classifies each bowel movement automatically and objectively, removing that source of error and producing a consistent record from one day to the next.

The Digestive Pattern view lays out three consecutive 30-day windows so they can be read side by side. The useful question isn't whether a given day was perfect — it's which direction the mix is moving.

A rising share in the Healthy band over the months generally points to balanced hydration, fiber, and transit working together.

There is no single correct result for everyone. What matters is the individual baseline, and whether anything has meaningfully shifted away from it. A pattern that stays mostly in the Healthy band over time suggests digestion has settled into a steady rhythm.
