What does a nephrologist do?
A nephrologist is a kidney specialist — a physician with years of advanced training in how the kidneys work and what to do when they don’t. Beyond the kidneys themselves, they manage the many things the kidneys touch: fluid balance, blood pressure, minerals and electrolytes, anemia, bone health, and the filtering of waste from your blood. When something points to a kidney concern, your primary care doctor usually refers you to a nephrologist to take a closer look.
It helps to know how a nephrologist differs from a urologist, because the two are easy to confuse. A nephrologist treats the kidneys medically — managing disease, blood pressure, and chemistry with medication and monitoring. A urologist is a surgeon who treats the urinary tract: removing stones, and caring for the bladder and prostate. The two often work side by side, and for kidney stones in particular, we focus on the medical side — preventing new stones — and coordinate with urology for any procedure.
Because kidney care is a long relationship rather than a single visit, the team you start with stays with you as your needs change — through monitoring, medication, and every later stage if it’s ever needed.
What conditions does a nephrologist treat?
Nephrologists care for a wide range of conditions — some that clearly start in the kidneys, and many that affect the kidneys from elsewhere in the body:
- Chronic kidney disease (CKD) — long-term loss of filtering ability, at every stage
- High blood pressure — both as a cause of kidney damage and a result of it, including pressure that’s hard to control
- Diabetes-related kidney disease — the leading cause of CKD nationwide
- Electrolyte & mineral problems — sodium, potassium, calcium, and phosphorus imbalances
- Blood or protein in the urine — often the earliest sign of kidney trouble
- Glomerular diseases — inflammation of the kidney’s filters, such as IgA nephropathy or lupus-related kidney disease
- Polycystic & inherited kidney disease
- Recurrent kidney stones — metabolic prevention, coordinated with urology
- Acute kidney injury — a sudden drop in function that needs evaluation and follow-up
- Kidney failure — including the medical care that comes with dialysis and transplant
For the conditions you’re most likely searching for, we have dedicated guides on chronic kidney disease and on high blood pressure & kidneys, along with our CKD management program for slowing kidney disease over time.
When should you see one?
Common reasons to be referred to Georgia Nephrology include:
- A low or falling filtering number (eGFR), or protein or blood in the urine
- Diabetes or high blood pressure that’s affecting the kidneys
- Blood pressure that’s hard to control
- Repeated kidney stones, or an electrolyte imbalance
- A family history of kidney disease
- An episode of acute kidney injury that needs follow-up
A good rule of thumb: earlier is better. Seeing a specialist sooner — rather than waiting until kidney function is very low — consistently leads to better outcomes.
If your primary care doctor has suggested a referral, it’s worth understanding that this is a positive, practical step — not a sign that something has gone badly wrong. Many people are sent for early evaluation or simple monitoring, and catching a kidney concern early is exactly what makes it most treatable.
What to expect at your first visit
Knowing what’s coming makes a first appointment far less stressful. Plan for it to run about an hour — longer than a routine visit, because your nephrologist is getting to know you. Generally, they will:
Review your full history
Current conditions — especially diabetes and blood pressure — family history of kidney disease, and every medication and supplement you take.
Ask how you’ve been feeling
Changes in urination, fatigue, swelling, sleep, appetite — because your experience matters as much as your labs.
Examine you
A focused physical exam — blood pressure, heart and lungs, and checking for swelling in the legs or feet — to read signs the labs can’t show.
Run tests
Typically blood work and a urine test, sometimes an ultrasound. Your doctor orders labs to be completed at one of our on-site labs about a week before your next visit, so results are ready to review when you’re seen.
Explain it in plain language
What your numbers mean, the likely cause, and the plan from here — so you leave knowing the next step.
How to prepare, and what to bring
A little preparation goes a long way. Bring:
- A list of all medications and supplements (or the bottles)
- Any recent lab results or records, if you have them
- Your insurance card, photo ID, and any required referral
- What you know of your family kidney history
- A written list of questions — easy to forget in the moment
- If it helps, a family member or friend for a second set of ears
Questions worth asking
- What’s causing my kidney issue, and what stage am I at?
- What can I do to protect my kidneys?
- Which of my medications affect my kidneys?
- How often will I be seen and tested, and what symptoms should prompt me to call?

Request an AppointmentHow we explain your results
Kidney numbers can look like a foreign language at first — eGFR, creatinine, uACR, potassium. Part of a good first visit is translating them. Two numbers tell most of the early story: your eGFR (how well your kidneys filter — higher is better) and your urine albumin, or uACR (how much protein is leaking into your urine — lower is better). We’ll tell you what yours are, what they mean together, and how we’ll track them over time.
You should leave your appointment knowing your numbers, what’s likely behind them, and the one or two things that matter most to do next.
Our aim is that you walk out understanding your own kidney health well enough to explain it to someone at home — not buried in jargon. To learn what the key numbers mean before you come in, see our chronic kidney disease guide.
Do I need a referral?
Many patients are referred by their primary care doctor, and some insurance plans require a referral to see a specialist. If you’re not sure, call us at 404-645-7150 and we’ll help you understand what your plan needs.
When you’re ready, you can find a location near you or meet our providers to see who you might see.
