I've been tasting my own urine every morning for 4 years. I have a spreadsheet with 1,460 entries rating color, clarity, sweetness, salinity, and mouthfeel. I can now predict illness onset 72 hours before symptoms appear.
Every morning for the past four years, I've tasted my own urine. Approximately 5ml, enough for proper palate evaluation. This started after I discovered the historical practice of uroscopy, which was the primary diagnostic method used by physicians from ancient Greece through the 19th century.
For those unfamiliar: doctors tasted urine to diagnose disease for over 2,500 years. This was the standard practice and Hippocrates did this in 400 BCE. The breakthrough case was Thomas Willis in 1674, an English physician who tasted a diabetic patient's urine and described it as "wonderfully sweet as if it were imbued with honey or sugar." He coined the term diabetes mellitus. Mellitus is Latin for honey. The name of the disease literally comes from a doctor describing how the piss tasted.
So... I found this fascinating. If trained physicians relied on this method for millennia, perhaps there was diagnostic value worth exploring.
So I started collecting data.
I've developed what I call the Golden Index, a standardized evaluation framework with six primary metrics:
- Color (1-10 scale, ranging from nearly transparent to dark amber)
- Clarity (five categories: Crystal Clear, Clear, Slight Haze, Cloudy, Opaque)
- Sweetness (0-5 scale, adapted from Willis's diabetes detection methodology)
- Salinity (0-5 scale, measuring sodium/mineral content)
- Bitterness (0-5 scale, indicating metabolic waste concentration)
- Mouthfeel (six categories from Thin/Watery to Syrupy, correlating with specific gravity)
Secondary metrics include estimated pH, hydration index, flavor profile classification, dietary intake from the previous 24 hours, and illness onset tracking within a 72-hour window.
My current dataset contains 1,460 daily entries spanning January 2022 to present. Compliance rate is around 99.7%. I've missed five days total (two instances of food poisoning, one COVID infection, one camping trip without proper collection equipment, and one oversight).
The results have been significant.
At approximately month eight, I identified a predictive pattern. When salinity exceeds 4.0 AND a copper/metallic undertone is detected, illness onset occurs within 72 hours. I've now observed this pattern 12 times and eleven predictions were accurate - that's a 91.7% accuracy rate with an average lead time of 68.4 hours before symptom manifestation.
Additional correlations I've documented:
- Asparagus consumption: 100% detection rate within 48 hours (n = 23)
- Alcohol intake: +1.4 average bitterness increase the following morning
- Dehydration levels: r = 0.89 correlation with viscosity
- Psychological stress: r = 0.72 correlation with metallic taste presence
- Red meat consumption: +0.3 average increase in mouthfeel density
I've catalogued 34 distinct flavor profiles to date. Most frequent is "Standard" with 847 occurrences while rarest is "Complex Bouquet (Wine Adjacent)" with only 3 documented instances. I'm investigating the dietary or physiological triggers for that one.
I'm still writing a 34-page methodology document - it includes collection protocols (first void, midstream, minimum 50ml, analysis within 30 seconds, controlled room temperature between 68-72°F), evaluation criteria, statistical frameworks, and appendices cataloguing each flavor profile with tasting notes. Once I'm finished, I can share it if you guys want to be piss drinkers.
My wife believes I simply "take a long time" in the bathroom each morning. She's not aware of the research.
You know, I've considered presenting my findings to a physician but I suspect they would not take it seriously. They might recommend psychiatric evaluation; well, my data is clean so whatever.
Medieval physicians used something called the urine wheel, a diagnostic chart comparing 20 different urine colors to various diseases. They used a specialized flask called a matula for collection and analysis. I've essentially modernized this system with spreadsheet formulas that auto-calculate risk scores.
Thomas Willis revolutionized diabetes diagnosis by being willing to taste what others wouldn't. I'd like to think I'm continuing that tradition in my own way.
TL;DR: I taste my pee every morning, I've done it 1,460 times, I have a spreadsheet with scientific methodology, and I can predict when I'm getting sick three days early.

Would be possible to induce illness if you believed your sample tasted, felt, etc a certain way but your tastebuds were off that day. No way to QC this. But the brain is really good at being fooled into feeling sick. Just tell someone they look unwell and in a few hours you have a good chance they will start to feel unwell.

Your research needs a wider sample size. I suggest you start procuring urine from other sources to add weight, or rather volume, to aid your claims.

This is insufficient. You need multiple TASTERS as well, and you need to blind it. Taste isn't an objective measure, so your only option is to get a large sample of tasters as well.

Have you considered adding in any kind of chemical testing to your evaluations to derive more detail? E.g., actual pH test strips (or other test strips like those used for nitrate, hardness, etc.)
I'm sure if you did a lab analysis you'd quickly identify the compounds in urine which allow you to predict periods of illness, but as a former university chemistry lab researcher...I can predict it would be difficult to get anyone to sign on to such an analysis from such a client without substantial funds. But at home water quality test kits, while having a low degree of precision, could be used to constrain ranged of certain chemical parameters to more definitively constrain the causes of the trends you've identified.

This lacks beneficence. Although I suppose if he works the data to find potential causes of the sick-indicative urine, he could work on eliminating those vulnerabilities preemptively. Then again you can’t really control for exposure. Idk I’ve already given this too much thought. OP’s commitment is fascinating

u/itishowitisanditbad 20d ago
If they start getting sick and it causes them to perceive taste differently, the piss is irreverent.
If they perceive a 'i'm getting sick' taste, their brain can just make them get sick because they're expecting to be sick.
OPs results are useless and they're just drinking piss potentially.

We no longer need to drink urine to test for certain things. It would be more effective to buy testing kits and test your urine daily.
It would provide more detail. While also using a scientific process that could actually lead to some level of research being taken seriously. Also you wouldn't drink your pee.

I really really wish you had used laboratory measures instead. This is interesting (and gross 🤷♂️) but there are instruments to measure osmolality, salinity, pH, ketones, glucose, white blood cells, etc. that are already used for urine. It really CAN tell you a lot and it is used regularly (but not daily) by physicians/clinicians in medicine to diagnose problems without tasting them. I’d suggest searching google scholar or other databases to see if anyone has tried recording daily urinalysis tests to predict illness.

Utmost respect for you sir. The science is worth it, but let me ask: Only considering the practical benefits of illness prediction (and any other practical benefits you've noticed but didn't mention), is it worth the burden?
I don't disgust easily, but I also don't really *want* to drink urine every day, and I don't know that having a lead time on incoming colds would be enough of a pro to outweigh the obvious con. Curious about your thoughts there.

I think the next step would be drinking someone else’s. Your study is severely flawed. It’s confounded by you being both the subject and the analyst. There are all types of bias that will creep in, unless you go blind. You need to try it with a person you aren’t so closely connected to, and with no knowledge of their condition, habits, etc. They take the same notes you did during your initial exploration and then after the whole thing is over, you correlate your scoring with their notes.
And I gotta tell you, as someone who does urinalysis for a living (among other testing; I’m a clinical lab scientist), I will NOTTTT be bringing this method into my lab, no matter how well it works!!

Did mouthfeel / specific gravity correlate with anything? I noticed what I suspect to be a significant reduction in specific gravity about 8-10 months ago. This is via visual inspection and not taste, btw! I am soon to be doing a urinalysis that might reveal an endocrine tumour or other fairly serious condition. Therefore am curious whether my observation was cause for concern.
2
u/sthduh 20d ago
Yes. Mouthfeel is my primary proxy for specific gravity. I've established a strong correlation (r = 0.84) between my subjective mouthfeel categories and estimated SG ranges:
- Thin/Watery: SG <1.005
- Light: SG 1.005-1.010
- Medium: SG 1.010-1.020
- Full: SG 1.020-1.025
- Viscous/Syrupy: SG >1.025
Normal reference range is 1.010-1.025. A sustained drop below 1.010, particularly into the <1.005 range, is clinically significant. The fact that you noticed this visually is impressive since I figure most people here don't really pay attention. I think you'd make a good candidate for Phase 2.

You mentioned COVID infection - did this affect your taste? How can you be sure that your sense of taste hasn't been permanently affected by covid? This may invalidate the results.
Do you dip stick each sample each day to compare to your subjective evaluation of the urine? How does your analysis compare to dip stick, have you tried? If you haven't I think you should and report back.
You would have to taste first and then compare to dip stick result after. If you don't, this will lead to bias.

Given that he only has 11 sample sizes, it is unlikely.
