Functional Gut Health

The Functional GI Metrics Your Doctor Cares About

Great gut health means regular, healthy poops. The Bristol Stool Scale and stool frequency have been the clinical standard for nearly 30 years — but research shows patients accurately recall their bowel habits only about 30% of the time after just one week.

Throne's approach

Throne's AI was trained by gastroenterologists to classify every stool on the Bristol Stool Scale. Frequency is captured automatically, no input required. You also have the option to log sessions manually when you're away to keep a complete history of your digestive pattern.

What you can learn

This is where the data becomes personal. Throne connects the dots between what you eat, how you live, and how your gut responds. See the before/after of a new diet. Track how travel disrupts your baseline. Notice that stress affects your digestion days before you feel it. Patterns emerge over time, so you can understand what's normal for your body and catch changes early.

Why do stool form and frequency actually matter?

Stool form and consistency are among the most validated signals in digestive health science. Throne reads them automatically, every single day.
Hydration

See Dehydration Before You Feel It

Doctors don’t measure hydration by asking how many glasses of water you drank. They measure urine concentration. Urine osmolality is the clinical gold standard because it reflects how hydrated your body actually is — regardless of intake. Even mild chronic dehydration impacts kidneys, cognition, and physical performance.

Throne's approach

Throne estimates clinical osmolality testing using optical urine color analysis. Every bathroom visit produces a hydration reading, no test strips, no lab, 
no effort.

What you can learn

See your real hydration trend throughout the day. Almost everyone is dehydrated when they wake up, and because dehydration shows up in your urine before you feel thirsty, most people don't realize it until the effects have already set in. Throne catches what your body won't tell you in time. Half of Throne Users see improved hydration in their first two weeks.

Bathroom Habits

Bathroom Habits That Matter

How long you sit matters. A 2025 Harvard-affiliated study linked prolonged sitting to a 46% higher risk of hemorrhoids. Time to evacuation reveals urgency and constipation patterns, signals rarely measured outside the clinic.

Throne's approach

Throne's sensor captures exact timestamps for session start, first evacuation, active window, wrap-up time, and completion. Ground-truth data, every session, automatically

What you can learn

Most people have no idea how long they spend on the toilet or whether their urgency patterns have shifted. Throne makes these invisible timelines visible — giving you a picture of bathroom habits that are clinically significant and within your control. Throne also sends gentle reminders when you've been sitting too long, so you can build better habits without thinking about it.

Prostate Health

Your Prostate Health Baseline

If you're a man over 40, your urologist cares about your flow rate. It's a foundational measurement for assessing prostate health. But most men never get a baseline reading — flow rate is typically only measured in the clinic once symptoms have already appeared.

Throne's approach

You can hear the difference between a strong stream and a weak one. Throne can measure it. Using acoustic analysis of standing sessions, Throne reconstructs your flow pattern at every visit — allowing you to see trends in your urinary health that were previously invisible.

What you can learn

Understand how your flow changes over time and spot early shifts that may be linked to prostate health, with clear data you can share with your doctor.

We track our steps, our sleep, our heart rate but one of the biggest predictors of long-term health has been ignored… until now. Throne fixes that gap.
Dr. David Rubin is one of the world's foremost experts on inflammatory bowel disease, serving as Chief of Gastroenterology at the University of Chicago Medicine. With over 600 published articles and 31,000 academic citations, he literally wrote the guidelines — including the 2025 American College of Gastroenterology standards for ulcerative colitis. He chairs the International Organization for the Study of IBD and has received the Sherman Prize, one of the most prestigious honors in the field. Dr. Rubin has dedicated his career to advancing early detection and prevention of serious GI disease, bringing world-class clinical science to everything he touches.
Throne’s innovative approach holds great promise to empower patients and non-patients with knowledge about their health. It has the potential to improve the accuracy and efficiency of clinical research as well.
Dr. Suzelle Moffitt has been practicing medicine since 1986. With nearly four decades at the intersection of clinical care, health law, and patient advocacy, she built a career spanning full-time medical practice and time as general counsel for a regional health system, before returning to frontline patient care — bringing a uniquely whole-picture perspective to medicine that few physicians can match.

She is also the mother of Throne's CEO, Scott Hickle — and in many ways, the spark behind the company itself. In the summer of 2023, Scott called her with a simple question: "Is there any medical utility to what's in people's waste?" What followed was a 45-minute conversation. In the field of geriatrics, Dr. Moffitt explained, it's well understood that gut motility slows with age — and patients become acutely aware of it. "I no longer give my patients my phone number," she told him, "because they'll send me so many pictures of their poop." She was the first to tell Scott that what he was building wasn't just interesting — it was genuinely needed.
When Scott first called me asking about health insights in people’s poop, I couldn't have imagined it would have ended up here. I'm biased (of course!), but I love the product and use it every day.
Dr. Vipul Jairath holds the McDonald Endowed Chair in IBD Clinical Research at Western University and trained at Oxford, where he earned his DPhil in clinical medicine. He's one of the world's leading experts on how to design clinical research that actually measures whether a gut health treatment works — the person research teams turn to when the stakes are high. With nearly 800 published studies and 16,000 citations, his work shapes the global standards by which digestive disease therapies are evaluated. Dr. Jairath brings some of the most rigorous scientific thinking in gastroenterology to everything he advises on.
Throne has the potential to change IBD research by improving data collection methods and endpoints, especially compared to patient recall.
Dr. Satish Rao holds the Harrison Distinguished Chair in Gastroenterology at Augusta University and is one of the rare physicians recognized as an outstanding researcher, distinguished educator, and master clinician — all three. With over 500 published papers, 20,000 academic citations, and 4 patents, he's a global authority on the gut-brain connection and how the digestive system actually moves. He pioneered several diagnostic techniques now used worldwide and has been named to "America's Top Doctors" for more than 25 consecutive years.
Throne is potentially helpful for monitoring bowel symptoms in constipated patients over longer time frames.
Dr. Mark Pimentel is the scientist who changed how the world understands IBS. As Executive Director of the MAST Program at Cedars-Sinai, he developed the first blood test to diagnose irritable bowel syndrome — proving once and for all that it's a real, organic disease, not "all in your head." He also pioneered the connection between gut bacteria, SIBO, and digestive symptoms that underpins modern microbiome medicine. With over 150 peer-reviewed papers and research featured in the New England Journal of Medicine, Dr. Pimentel has spent his career turning gut science into answers patients can actually use.
Throne has the potential to both improve IBD patient care today and speed up valid clinical research in the coming years.
