Wisdom in the waste: Why tracking your poop Is key to your health
Most of us diligently track our steps, calories, sleep, or heart rate these days. But there’s one health metric which is the single biggest predictor of long term health we literally flush away without a second thought: our daily poop.
Yes, we’re going there…your poop.
In this article, I’ll explain from my perspective as Chief Science Officer at Throne, why checking your poop (and pee) is one of the most underrated health habits you can develop, and how new technology can help turn this “taboo” into actionable health insights.
The overlooked health metric: your daily poop
When it comes to your health, poop is essential. What comes out of your body can tell a lot about what’s happening inside. In fact, doctors often ask about bowel habits for this very reason. Changes in your stool’s appearance, frequency, or smell can be early warning signs of dietary issues or even medical conditions. Persistent black stool, for example, might signal internal bleeding; green stool could reflect dietary changes or gut transit speed; unusually foul odors might indicate malabsorption.
Fluctuations in your stool reflect changes in your diet, hydration, mood, and activity level, and sometimes they can even be a warning sign of a serious medical condition. In short, your daily bowel movement is like a report card from your gut and ignoring it means missing out on vital information.
To drive home how much you can learn from your waste, here are just a few health insights your poop can reveal:
Hydration and fiber status
Hard, lumpy stools or infrequent bowel movements often suggest not enough fiber or fluids in your diet (a sign of constipation). Conversely, very loose or watery stool may indicate too much fluid and not enough fiber. Your poop’s consistency is a direct reflection of how well you’re nourishing and hydrating your body.
Digestive speed and balance:
The form of your stool (classified by the Bristol Stool Scale) correlates with gut transit time. Types 1-2 (hard pellets or lumpy sausage) mean things moved too slowly (constipation), whereas Types 6-7 (mushy or entirely liquid) mean things moved too quickly (diarrhea). Ideally, Type 3 or 4 (smooth, soft, snake-like stool) is the gold standard of healthy digestion
Internal bleeding or disease:
The color of stool can be a red flag. For example, black, tarry stool can indicate gastrointestinal bleeding and should never be ignored. Bright red streaks might point to hemorrhoids or bleeding in the lower tract. Pale, clay-colored poop can signal liver or gallbladder issues due to lack of bile. Simply glancing at stool color can provide clues about conditions that might otherwise go unnoticed.
Chronic gut conditions:
Long-term patterns in your bowel movements can help monitor or even predict conditions like irritable bowel syndrome (IBS), inflammatory bowel disease (e.g. ulcerative colitis), or even colorectal cancer. Researchers have found that analyzing waste can aid in tracking these chronic conditions; sometimes flagging issues before you experience severe symptoms. For instance, an unexplained shift toward persistent diarrhea or constipation could warrant a check-in with your doctor sooner rather than later.
Diet and lifestyle effects:
Your poop also reflects day-to-day lifestyle factors. Sudden changes when you travel or experience stress? Noticing you always have a bowel movement after your morning coffee? That’s your gut’s internal clock at work. Most people have a fairly regular “poop schedule” (anywhere from three times a day to three times a week is normal). Everyone’s routine is different, but if you completely lose your normal pattern, it may indicate something is off in your diet or routine. The bowel is wired to our circadian rhythms…in fact, colonic motility follows a daily rhythm, with most people going in the morning and rarely at night. Disruptions to this rhythm (like shift work or jet lag) often result in temporary constipation or diarrhea. By tracking your habits, you can quickly spot when life’s changes are throwing your gut out of balance.
As you can see, there’s a lot of “wisdom in the waste.” Your stool provides both qualitative data (color, shape, texture, smell) and quantitative data (frequency, timing, duration of bowel movement) that together paint a comprehensive picture of your gut health. The key is to observe trends over time rather than fixate on any single bowel movement.
One odd poop isn’t cause for alarm (we all have the occasional “what was that?” moment), but a trend of changes is worth noting. Are your stools gradually getting harder each week? Are you going from clockwork regularity to unpredictable timing? Such subtle shifts from your baseline can be predictive of issues before bigger symptoms manifest. For example, creeping towards constipation…say, going from daily to every other day, with stool form moving from Type 4 to Type 2…might let you intervene early (by upping fiber or water) before you end up terribly bunged up. Small deviations from your personal norm are often the earliest clues that something in your gut health needs attention.
Turning taboo into tool: How technology helps you track (without the ick)
By now, you might be thinking, “Okay, it makes sense that poop is important…but do I really have to inspect the toilet bowl every day?” Thankfully, modern technology is stepping up to make this much easier (and less icky) than it sounds. In the age of wearable health trackers like WHOOP® bands giving us insights on sleep and recovery, it was only a matter of time before someone figured out how to quantify our bathroom habits. After all, your toilet sees more about your health than your doctor ever could.
This is where smart toilet devices come in…and it’s exactly what we’re building at Throne. Rather than being a whole new toilet, Throne One is a small AI-powered device that clips onto your existing toilet. It uses sensors and a downward-facing camera (don’t worry, it only sees what’s in the bowl, nothing else) to automatically analyze your poop and pee each time you go.
Think of it like having a personal lab technician in your toilet bowl, turning your waste into health insights. Our physician-trained AI can identify your stool form (using the Bristol Stool Scale categories), stool color, even metrics like how long your “session” took and how often you’re going…all without you having to log anything manually. On the urine side, it can gauge your hydration level (via urine color and osmolality) and even measure urine flow rate (useful for monitoring prostate health in men). All this data is sent securely to an app on your phone, where you can see trends and get personalized feedback.
What’s revolutionary here is the combination of quantitative trend tracking with qualitative analysis, done automatically. Monitoring bowel movements can provide valuable insights into digestive health and nutrient absorption, and even give early warning signs for more serious conditions…and now you don’t have to rely on memory or messy charts to do it. The Throne device will establish your baseline metrics (e.g. your personal Gut Health Score, average stool type, typical frequency and time of day, Hydration Score, etc.), and then alert you to deviations or gradual changes. It’s like having a smart coach for your gut: if you’re drifting toward constipation or your hydration is trending low, you’ll get a nudge to take action before it becomes a problem.
Over time, you can correlate how changes in diet, stress, or routine affect your outputs, taking the guesswork out of phrases like “I feel off my gut game lately.”
Crucially, by making this fully automated and private, we hope to make the taboo less taboo. No one really likes talking about poop, let alone analyzing it. But when a device can do the observing for you and present it in clean, digestible (no pun intended) charts, it normalizes the whole process.
We’ve ignored this huge predictor of health until now and Throne fixes that gap by integrating gut metrics into your everyday health tracking.
The result is that checking your digestive health can be as routine as checking your step count or heart rate. Early beta users have found it liberating: instead of awkward bathroom selfies or vague recollections, they get concrete data. And with AI-driven pattern recognition, we can even suggest science-backed tips: for example, increase fiber intake if stool is consistently on the harder side, or maybe adjust your meal timing if your circadian poop rhythm is off. It’s actionable, “science-backed” guidance derived from your own body’s signals.
Not just “how often” but how well you poop
Counting trips (“three a day” vs “three a week”) is quantitative data. Useful, yes…but incomplete. Gut health lives in the qualitative details of each bowel movement. Think of it as moving from “step count” to gait quality in running: frequency matters, but form tells the deeper story.
Here are the qualitative metrics that matter; the stuff you can’t track reliably in your head, but your Throne device either can do today and will be able to in the coming months:
- Form (Bristol Stool Form Scale); consistency over time
- Aim for Type 3–4 (smooth, soft, log-like).
- Drift tells you more than any single reading: creeping toward Type 1–2 = slowing transit/constipation risk; toward Type 6–7 = speeding transit/irritation.
- What Throne captures: automated BSS classification per event + variance week to week.
- Ease of passage; the “effort index”
- A healthy BM (bowel movement) is easy to start, easy to finish: minimal straining, little breath-holding.
- Practical proxy: time on the toilet. <5 minutes, no straining = green. Prolonged sits or repeated attempts = yellow/red.
- What Throne captures: session duration, repeat visits, pattern recognition for “stop-start” days.
- Completeness; do you feel “done”?
- Incomplete evacuation is common in low-motility states or pelvic floor disfunction.
- What Throne infers: return-within-30-minutes events + short, clustered sessions.
- Urgency & timing: circadian rhythm fidelity
- Stable “go window” most mornings is normal; new urgency or nocturnal BMs are flags.
- What Throne trends: time-of-day heatmaps, regularity score, nocturnal events (rare = normal).
- Color & sheen; chemistry in plain sight
- Brown is bile doing its job. Very pale (acholic) can signal bile flow issues; black/tarry needs medical attention; red may be hemorrhoids or lower-GI bleeding.
- Oily sheen or persistent floating can suggest fat malabsorption.
- What Throne captures: color classification and surface optics (sheen/reflectance) for patterns over time.
- Fragmentation & shape
- Pebbles, cracks, or “cornflake” edges = dehydration/slow transit.
- Ragged, unformed edges = rapid transit or irritants.
- What Throne maps: edge integrity + fragment count as qualitative texture metrics.
- Wipe load (yes, really)
- A “single-wipe clean” is a decent proxy for good form + complete evacuation.
- What Throne can estimate: paper use proxy (session duration)
- Odor character (pattern, not perfume notes)
- Sudden, persistent acrid odor shift can follow antibiotics, infections, or diet changes.
- What Throne notes: event-level flags (user-reported) linked to dietary or medication changes for correlations.
- Hydration echoes in stool + urine
- Hard pellets + concentrated urine signal under-hydration; loose output with very pale urine suggests the opposite.
- What Throne couples: stool form with urine color/osmolality proxy to coach fluid intake.
Quality beats quantity. The gold standard is smooth, soft, easy to pass, minimal wiping, under five minutes, at your usual time.
From Qual → Quant: a Bathroom Habits Score
Just like athletes track recovery, we combine form, ease, completeness, timing, and stability into a single Bathroom Habits Score. It’s not a one-off snapshot; it’s trend-aware. Small, repeated nudges away from your baseline (harder form, longer sits, later timing) are often early signals…letting you course-correct with fiber, fluids, meal timing, or stress management before symptoms explode.
Why a device beats memory (and shame)
You can’t accurately remember last Tuesday’s stool edge integrity…and you shouldn’t have to. Passive, private, objective capture removes guesswork and the awkwardness. Throne establishes your personal normal, then watches for micro-migrations:
- Gradual shift from Type 4 → 3 → 2
- Time on toilet creeping from 3 → 7 → 10 minutes
- Morning “go window” sliding later (circadian drift)
- More “not quite done” returns
Those micro-trends beat macro-surprises. It’s the gut equivalent of catching a sleep-debt build-up on ŌURA or a recovery dip on WHOOP before you feel wrecked.
A new era of gut health awareness
By shedding the awkwardness and embracing this information, you can become proactive about your gut health, catch potential issues early, and optimize your wellness in ways you might never have considered. We live in an age where data from sleep apps, heart-rate monitors, and DNA tests are all used to personalize our health; it’s high time we include the data from our daily bathroom visits as well.
By routinely checking in on your bowel habits (whether manually or with the help of a smart device) you’ll develop a finely tuned sense for when your body is in balance and when it might need some help.
So let’s make poop-checking less taboo and more routine. Pay attention to the signals your gut is sending. Maybe that means glancing in the bowl an extra second or using a high-tech helper to do it for you…whatever works! Your future self (and your doctor) will thank you for the vigilance.
In the end, listening to your gut is more than just a figure of speech. By tracking your poop, you’re literally listening to your gut’s data…and that could be a game-changer for your health.
Remember: Don’t flush away the wisdom in your waste. It might just save your butt (literally and figuratively) in the long run.
