LIVE ESTIMATE
850,274,891
people worldwide are living with kidney disease right now — about 1 in 10 adults.
A live estimate from global prevalence data (ISN / GBD), not a diagnosis counter. We show it for one reason: a diagnosis can feel isolating, and you are far from alone. Hundreds of millions are learning to live well with kidney disease.
TWO WAYS IN
Where would you like to begin?
The same evidence, told two ways — plain and reassuring for patients, fast and citable for clinicians.
FOR PATIENTS & FAMILIES
Newly diagnosed?
Start here, gently.
No jargon, no fear. Understand what your diagnosis means, what your lab numbers say, and what to ask at your next appointment.
- Understand what your diagnosis actually means
- Make sense of your eGFR, creatinine and other labs
- A checklist of questions for your next appointment
- Everything in your language, written plainly
FOR CLINICIANS & TRAINEES
Bedside-ready,
fully referenced.
Guideline summaries, calculators and dosing you can trust at the point of care — every claim linked to its KDIGO, ADA or ACC/AHA source.
- Concise, staged guideline summaries
- Validated calculators and risk tools
- Drug selection and dosing in reduced kidney function
- Every statement linked to its primary source

WHY YOU CAN TRUST IT
Written by a doctor. Anchored to the evidence.
Every guide is written and kept current by Dr. William Rivero, a practising nephrologist — one clinician, one voice, no committee and no sponsor. When guidelines change, the library changes with them.
Made to read alongside your doctor — never instead of one.
Physician-written
Authored and maintained by a nephrologist — not a content team, sponsor or algorithm.
Guideline-anchored
Every recommendation traces back to KDIGO, ADA or ACC/AHA guidance.
Always free
No ads, no paywall, no account required. Open to every patient, everywhere.
