Dr. Bismah Irfan, MD holds an active Arizona medical license and works with Arizona patients by video visit. She is a board certified nephrologist who spends the first appointment on one question most Arizona patients have never been asked: what started the damage, and how much of it can still be moved.
From Phoenix and Tucson out to the smaller communities where the nearest nephrologist is an hour of highway away, the whole thing runs by video visit.
The dry heat matters more than most people are told. Chronic low-grade dehydration concentrates urine, which pushes both stone formation and extra strain on kidneys that are already struggling. Arizona also has a large retirement population, and kidney function that slips quietly after 60 is usually written off as normal aging when something else is driving it.
Patients come to us from Phoenix, Tucson, Mesa, Chandler, Scottsdale, Gilbert and the rest of Arizona.
Functional medicine gets a lot of loose claims attached to it. This is the conventional training underneath it.
Internal Medicine and Nephrology, both through the American Board of Internal Medicine, plus Lifestyle Medicine (ABLM).
Nephrology fellowship at Albert Einstein College of Medicine in New York, internal medicine residency at the University of Illinois.
Former assistant professor at Cleveland Clinic Lerner College of Medicine.
Trained through the Institute for Functional Medicine after her own rheumatoid arthritis diagnosis, and built the HEAL protocol around what she found.
Every one of these has causes underneath it. That is where the work starts.
Slowing progression and protecting the function you still have.
The most common driver of CKD, and the one where root-cause work pays off fastest.
Blood pressure damages kidneys, damaged kidneys raise blood pressure. We work on both ends.
Genetic, but the rate of progression is not fixed.
Autoimmune kidney involvement, managed alongside your rheumatology care.
What to do after an injury so it does not become chronic.
Dehydration is the lever almost nobody pulls properly. Concentrated urine drives stone formation, and repeated stones leave scarring behind. In a state where you sweat out fluid without noticing, hydration strategy is a real part of the plan and not a throwaway line.
Worth reading next: how stone prevention is built into a kidney diet.
Every step below happens without you leaving Arizona. Arizona does not change its clocks, so Phoenix is two hours behind the Houston clinic in summer and one hour behind in winter. Appointment times are confirmed in your own time zone.
The qualification form asks about your stage, your history and what you have already tried, so the first conversation is not spent on paperwork.
No pressure and no diagnosis on this call. It exists so you can ask what the program involves and decide whether a full consultation makes sense. If you already know, you can skip it and book the consultation.
A 150 minute review with Dr. Bismah Irfan of your labs, imaging, medication list, diet and history. This is the appointment where you get an answer to why the damage started.
Testing that goes past the standard kidney panel: toxin load, infections, immune and metabolic markers, nutrient status. Collection is done near you or by kit at home.
A personalized plan covering nutrition, targeted supplementation, detoxification and the medical side, with scheduled follow-ups so it gets adjusted as your numbers move.
Some of what we offer has to be done in a room: EBOO, IV chelation, hyperbaric oxygen and stem cell and exosome therapy. Patients fly into Houston for a concentrated block of treatment and continue by video from home. Phoenix to Houston is about two and a half hours in the air.

“You are a nephrologist and a functional medicine doctor, which we had been looking for. We did not find one that combines both.”

Yes. Dr. Bismah Irfan holds an active Arizona medical license, so Arizona residents can be seen by video visit anywhere in the state.
No, and most patients do not. Functional nephrology runs alongside conventional care. We look for the causes behind the numbers, your existing team keeps doing what it does, and nothing in your medication plan changes without your physicians in the loop.
You send your records ahead of time, then meet Dr. Bismah Irfan by secure video. Lab draws and imaging are done locally near you and the results come back to us. The only reason to travel is if you want the in-clinic therapies that have to be done in person.
Chronic kidney disease at every stage, diabetic and hypertensive kidney disease, polycystic kidney disease, lupus nephritis, proteinuria, recurrent stones and recovery after acute kidney injury. If your case is not a fit, we will tell you on the call rather than after you have paid for a program.
Late stage is harder. It is still worth doing. The goal shifts toward protecting the function you have left, taking load off the kidneys and improving how you feel day to day. What is realistic for your stage is something Dr. Bismah Irfan will tell you honestly on the consult.

The qualification form is short. If your case is not a fit for this kind of care, we will say so.
