Digestion

Your poop is talking.
Are you listening?

Your stool is one of the most responsive indicators of what's happening inside your body. It reacts to what you eat, how you sleep, your stress levels, even that extra glass of wine last night.

That's what makes it so powerful.

Your stool can reveal:

  • Diet impact. See how different foods affect your digestion within days, not months

  • Stress response. Your gut is often the first place stress shows up in your body

  • Fiber and hydration levels. Consistency and frequency tell you more than you think

  • Early warning signs. Changes in color, shape, or pattern can signal issues worth investigating

Hydration

Your pee holds clues you're probably missing.

Most people think of urine as just a hydration check. Yellow means drink more water, clear means you're good. But that's barely scratching the surface.

Your pee can tell you about so much more—including things most people don't think about.

What your urine can reveal:

  • Hydration level: Yes, but with actual trends over time, not just a single glance

  • Urinary function: Flow rate, frequency, and patterns can indicate how well your urinary system is working

  • Prostate health: For men, changes in urinary patterns are often the earliest sign of prostate issues

  • Kidney function indicators: Color and consistency changes can signal issues worth discussing with your doctor

Throne tracks these patterns passively, so you can catch changes early—without ever having to think about it.

How does using my HSA/FSA account save me money?

HSA/FSA accounts were created so individuals could use pre-tax money to pay for expenses used to treat, mitigate, or prevent a diagnosed medical condition. Because HSA/FSAs use pre-tax money, you’re getting more purchasing power for your dollars. Rather than pay taxes on income and then spend it on health items, qualified customers can use pre-tax funds to invest in their health. An individual can contribute up to $4,150 pretax to their HSA per year, or $8,300 for a family (plus an additional $1,000 if you are at least 55 years old. Individuals can contribute up to $3,200 pretax to their FSA per year (with an additional $500 in employer contributions allowed).
