What Does a Nephrologist Do—and When Should You See One?

A nephrologist is a physician who evaluates kidney disease, difficult blood pressure, fluid balance and related blood-test problems. Seeing a kidney specialist does not mean you need dialysis.

Three things to know

  • Kidney care often starts with reviewing blood and urine results.
  • Your primary-care physician and nephrologist can work together.
  • Early evaluation can clarify the cause and guide monitoring.

What a kidney specialist evaluates

Common reasons for a nephrology consultation include reduced kidney function, persistent protein in urine, repeated kidney stones, abnormal potassium or sodium, and blood pressure that remains difficult to control. The reason for the appointment matters more than whether you have symptoms: early kidney problems may not make you feel ill.

How nephrology and Internal Medicine connect

Diabetes, blood pressure, heart health and medicines can all affect the kidneys. Internal Medicine looks at the broader adult medical picture; nephrology adds a focused kidney assessment. Your clinicians may divide responsibilities for testing, prescriptions and follow-up so that recommendations stay coordinated.

What happens at the first visit

Expect a discussion of your medical history, family history, medicines, supplements and laboratory trends. Bring earlier results as well as the latest report. Depending on the concern, an examination, repeat blood or urine testing, or imaging may be needed. Telehealth may suit some records-based discussions, but cannot replace every examination.

Nephrologist or urologist?

A nephrologist usually focuses on kidney function and medical kidney conditions. A urologist treats many structural urinary problems and performs procedures, including removal of obstructing stones. Some people need both. Blood in urine should be evaluated rather than assigned to one specialty without assessment.

Questions to bring to your visit

  • What finding prompted my referral?
  • Which tests should I bring?
  • Who will manage my medicines and follow-up?

Common questions

Do I need a referral?

AspireMed accepts direct consultation requests. Your insurance plan may still require a referral or authorization.

Can a kidney visit be virtual?

Some consultations can begin virtually when clinically suitable. An office examination or additional testing may be needed.
