Dr. Banshi M. Rathi, MD

Dr. Banshi M. Rathi, MD Nephrologist and Kidney Care

Dr. Banshi M. Rathi, MD, is a board-certified nephrologist who provides specialist care for adults with kidney disease, difficult-to-control high blood pressure, electrolyte imbalances, fluid retention, and conditions that may require dialysis. His professional background includes training in internal medicine followed by a fellowship in nephrology.

Patients may consult Dr. Rathi after abnormal kidney blood tests, protein or blood in the urine, recurring swelling, reduced kidney function, or concerns related to diabetes and high blood pressure.

Seeing a nephrologist does not automatically mean that dialysis is needed. Many patients are referred early so the cause of kidney changes can be identified and further loss of function may be slowed.

Clinical specialties	Nephrology and internal medicine	Adult kidney and general medical care

Dr. Rathi completed medical school at Maulana Azad Medical College before undertaking internal medicine residency training at Rochester General Hospital. He later completed fellowship training in nephrology through New York Medical College.

Internal medicine training provides broad experience with adult medical conditions. This is important in nephrology because kidney function may be affected by diabetes, heart disease, blood pressure, infection, autoimmune disorders, medication, and liver disease.

Nephrology fellowship training adds focused preparation in kidney disease, dialysis, electrolyte disorders, hypertension, kidney biopsy findings, and the medical care of patients with kidney failure.

Board Certification and Professional Credentials

Dr. Rathi is listed as a board-certified nephrologist.

His professional credentials include:

• MD, meaning Doctor of Medicine
• Residency training in internal medicine
• Fellowship training in nephrology
• Board certification in nephrology
• Experience in outpatient and hospital kidney care
• Professional involvement in medical education and kidney disease research

Board certification is different from medical licensing. A medical license permits a physician to practice, while certification reflects specialist education, supervised training, and professional assessment.

What a Nephrologist Does

A nephrologist is a physician who diagnoses and treats diseases affecting the kidneys.

The kidneys perform several essential tasks. They remove waste and extra water from the blood, help balance minerals, support blood pressure regulation, activate vitamin D, and produce signals connected with red blood cell production.

Kidney problems can therefore affect more than urination. They may contribute to swelling, anemia, bone weakness, blood pressure changes, heart strain, muscle problems, or abnormal potassium and sodium levels.

A patient may be referred to a nephrologist when:

• Creatinine levels are elevated
• Estimated kidney filtration has decreased
• Protein appears in the urine
• Blood is found in the urine
• Blood pressure remains difficult to control
• Swelling continues without a clear cause
• Diabetes has affected kidney tests
• Kidney function changes after illness or surgery
• Electrolyte levels remain abnormal
• Dialysis may be needed
• Another doctor suspects an inflammatory kidney disease

Chronic Kidney Disease

Chronic kidney disease means the kidneys have ongoing damage or reduced function that continues over time.

Diabetes and high blood pressure are common causes, but kidney disease may also result from autoimmune conditions, inherited disorders, repeated infections, blood vessel disease, medication, or diseases affecting the kidney filters.

Early chronic kidney disease often causes no noticeable symptoms. Blood and urine testing may therefore identify a problem before the patient feels unwell. Two commonly used measurements are estimated glomerular filtration rate and urine albumin.

Possible symptoms in more advanced disease include:

• Swelling in the feet or ankles
• Unusual tiredness
• Reduced appetite
• Nausea
• Changes in urination
• Muscle cramps
• Shortness of breath
• Dry or itchy skin
• Difficulty concentrating
• Weakness

These symptoms can also occur with other medical conditions. Laboratory testing and clinical assessment are needed to determine whether the kidneys are involved.

Kidney Function Testing

Kidney health is often evaluated with a combination of blood tests, urine tests, physical examination, and imaging.

Blood Testing

A blood creatinine test helps estimate how effectively the kidneys are filtering.

The result may be used to calculate estimated glomerular filtration rate, commonly written as eGFR. The number is interpreted together with age, medical history, urine findings, and changes over time.

One abnormal result does not always confirm chronic kidney disease. Dehydration, infection, medication, recent illness, muscle-related factors, and temporary changes can affect creatinine.

Urine Testing

Urine testing may check for:

• Albumin
• Protein
• Blood
• Infection
• Glucose
• Abnormal cells
• Crystals

Protein in the urine may be an early sign that the kidney filters are damaged, even when blood-test results remain close to the expected range.

Imaging

Kidney imaging may include ultrasound, CT, MRI, or vascular testing.

Imaging can help identify:

• Kidney size
• Cysts
• Stones
• Urinary blockage
• Structural differences
• Blood-flow concerns
• Changes linked with long-term disease

Diabetic Kidney Disease

Diabetes can gradually damage the small blood vessels within the kidneys.

Patients with diabetes may need regular monitoring that includes:

• Kidney filtration testing
• Urine albumin testing
• Blood pressure measurement
• Blood sugar review
• Medication assessment
• Potassium monitoring
• Cardiovascular risk management

Kidney damage can develop without pain or obvious urinary symptoms. Regular testing is therefore important even when diabetes appears stable.

Treatment may focus on improving blood sugar and blood pressure control, using kidney-protective medication when appropriate, reducing cardiovascular risk, and reviewing medicines that could place additional strain on the kidneys.

High Blood Pressure and Kidney Disease

High blood pressure can damage the kidneys, while reduced kidney function can make blood pressure harder to control.

This creates a cycle in which each condition may worsen the other.

A kidney-focused blood pressure assessment may include:

• Home blood pressure readings
• Medication timing
• Sodium intake
• Kidney function
• Potassium levels
• Fluid retention
• Sleep concerns
• Other cardiovascular risks
• Possible secondary causes of hypertension

Patients should bring several days of home readings when possible. Each record should include the date, time, blood pressure, pulse, and whether medication had already been taken.

Medication should not be increased, reduced, or stopped without direct medical advice.

Protein or Blood in the Urine

Protein in the urine may indicate that the kidney filters are allowing substances to pass through that would normally remain in the bloodstream.

Blood in the urine may be related to:

• Kidney inflammation
• Stones
• Infection
• Urinary tract conditions
• Prostate concerns
• Medication
• Injury
• Other kidney or bladder disorders

Visible blood should be assessed, but blood found only during laboratory testing may also need follow-up.

The evaluation may involve repeat urine testing, imaging, blood tests, or referral to a urologist when the suspected cause involves the bladder, prostate, or urinary tract.

Glomerular Disease

The glomeruli are tiny filtering structures inside the kidneys. Diseases affecting these filters may cause protein leakage, blood in the urine, swelling, high blood pressure, or declining kidney function.

Glomerular disorders may be connected with:

• Autoimmune disease
• Infection
• Diabetes
• Inherited conditions
• Certain medicines
• Conditions affecting blood vessels
• An unknown cause

Evaluation may include:

• Urine protein measurement
• Blood testing
• Autoimmune testing
• Infection testing
• Kidney imaging
• Kidney biopsy in selected cases

A kidney biopsy removes a very small sample of tissue for examination. It may help identify the specific disease and guide treatment when laboratory and imaging results do not provide enough information.

Glomerular disease can sometimes progress quickly, which is why increasing swelling, reduced urination, breathing difficulty, or rapidly changing kidney tests require prompt attention.

Acute Kidney Injury

Acute kidney injury is a sudden reduction in kidney function.

It may develop over hours or days because of:

• Severe dehydration
• Major infection
• Low blood pressure
• Heart problems
• Urinary blockage
• Surgery
• Contrast material
• Medication
• Severe inflammation
• Major injury

Treatment depends on the cause. It may involve fluids, medication adjustment, infection treatment, relief of a blockage, hospital monitoring, or temporary dialysis.

Some patients recover much of their kidney function, while others are left with chronic kidney disease. Follow-up testing after hospital discharge can help determine whether kidney function has returned to its previous level.

Fluid Retention and Swelling

Swelling may occur when the kidneys cannot remove sodium and extra fluid effectively.

It may be noticed in the:

• Feet
• Ankles
• Legs
• Hands
• Face
• Abdomen

Swelling is not always caused by kidney disease. Heart conditions, liver disease, vein problems, medication, pregnancy, and other medical concerns can produce similar symptoms.

Dr. Rathi may review kidney function, urine protein, heart history, medication, sodium intake, and recent weight changes before determining the likely cause.

A rapid increase in weight over a few days may indicate fluid buildup rather than body-fat change.

Electrolyte Disorders

The kidneys help balance important minerals in the bloodstream.

These include:

• Potassium
• Sodium
• Calcium
• Phosphate
• Bicarbonate
• Magnesium

Abnormal levels may affect muscle function, heart rhythm, blood pressure, thinking, and general strength.

Potassium changes can be especially important because very high or very low levels may affect the heartbeat.

Patients should not begin potassium, magnesium, salt substitutes, or electrolyte supplements without checking whether they are suitable for their kidney function and medication.

Kidney-Related Anemia

Healthy kidneys produce a hormone that helps the body make red blood cells.

When kidney function declines, the body may produce fewer red blood cells, leading to anemia.

Possible symptoms include:

• Tiredness
• Weakness
• Shortness of breath
• Reduced exercise ability
• Dizziness
• Headaches
• Pale skin
• A rapid heartbeat

Anemia in a patient with kidney disease may also be caused by iron deficiency, bleeding, vitamin deficiency, inflammation, or another medical condition.

Treatment may include iron, vitamin replacement, medicine that supports red blood cell production, or treatment of another underlying cause.

Bone and Mineral Health

Kidney disease can change how the body manages calcium, phosphate, vitamin D, and parathyroid hormone.

Over time, these changes may affect bone strength and blood vessels.

Monitoring may include:

• Calcium
• Phosphate
• Vitamin D
• Parathyroid hormone
• Alkaline phosphatase
• Bone health history

Treatment may involve dietary changes, phosphate-binding medicine, vitamin D-related treatment, or adjustments to dialysis.

Patients should not assume that an over-the-counter calcium or vitamin D supplement is automatically suitable for advanced kidney disease.

Medication Safety and Kidney Function

Some medicines are removed from the body through the kidneys. Reduced kidney function may therefore require dose adjustments.

Medication review may include:

• Prescription medicines
• Over-the-counter pain relievers
• Antibiotics
• Diabetes medicines
• Blood pressure medicines
• Diuretics
• Vitamins
• Herbal products
• Contrast exposure
• Supplements

Certain anti-inflammatory pain relievers can increase the risk of kidney injury, especially in patients with kidney disease, diabetes, high blood pressure, dehydration, or heart conditions.

Patients should tell Dr. Rathi about every medicine and supplement they use, including products taken only occasionally.

Dialysis Assessment

Dialysis replaces part of the kidneys’ filtering work when kidney function becomes severely reduced.

A dialysis discussion may include:

• Whether dialysis is currently necessary
• How quickly kidney function is changing
• Symptoms caused by kidney failure
• Hemodialysis
• Peritoneal dialysis
• Treatment at home or in a center
• Vascular access planning
• Lifestyle and work considerations
• Kidney transplant evaluation
• Conservative kidney care

The decision to start dialysis is not based on one laboratory number alone. Symptoms, fluid control, potassium levels, nutrition, overall health, and the patient’s goals may all influence timing.

Doctiplus includes dialysis assessment among its kidney-related services.

Hemodialysis

Hemodialysis uses a machine and filter to remove waste and extra water from the blood.

Blood travels from the body through the dialysis system and is then returned.

Long-term hemodialysis usually requires reliable access to the bloodstream. This may involve:

• An arteriovenous fistula
• An arteriovenous graft
• A temporary or permanent catheter

Access planning may begin before dialysis is urgently needed so there is time for the selected access to heal and become usable.

Hemodialysis supports kidney function but does not cure permanent kidney failure.

Peritoneal Dialysis

Peritoneal dialysis uses the lining inside the abdomen to filter waste and fluid.

A soft catheter is placed in the abdomen, and dialysis solution is moved in and out according to the treatment schedule.

This option may allow more treatment to be completed at home, but it requires training, clean technique, storage space, and regular monitoring.

The choice between hemodialysis and peritoneal dialysis depends on medical needs, home support, lifestyle, previous abdominal surgery, personal preference, and the ability to manage treatment safely.

Kidney Transplant Coordination

A kidney transplant may be an option for some patients with advanced kidney failure.

Evaluation may consider:

• Heart and lung health
• Infection risk
• Cancer history
• Medication use
• Ability to follow long-term care
• Available support
• Living or deceased donor options
• Other medical conditions

A nephrologist may help identify when referral to a transplant center is appropriate and continue kidney care before and after transplantation.

Transplant recipients normally need long-term medication to reduce the risk that the immune system rejects the donated kidney.

Patients can also review another kidney specialist profile on Doctiplus or use the directory to find doctors by specialty.

What Patients Can Expect During an Appointment

The consultation usually begins with a review of symptoms, medical history, medicines, and previous laboratory results.

Dr. Rathi may ask:

• When did the kidney-test changes begin?
• Is diabetes present?
• How well is blood pressure controlled?
• Has swelling developed?
• Has urination changed?
• Have kidney stones occurred?
• Has blood or protein been found in the urine?
• Has the patient recently been hospitalized?
• Are anti-inflammatory pain medicines used?
• Is there a family history of kidney disease?
• Have contrast scans recently been completed?
• Which medicines and supplements are being taken?

The examination may include checking:

• Blood pressure
• Pulse
• Weight
• Swelling
• Heart and lung sounds
• Hydration
• Skin changes
• Signs of anemia
• Circulation

The next step may involve blood testing, urine testing, imaging, medication adjustment, dietary guidance, dialysis planning, or coordination with another specialist.

Preparing for the Appointment

Patients can prepare by bringing:

• A complete medication list
• Medication dosages
• Supplement information
• Allergy details
• Recent kidney blood tests
• Urine-test results
• Home blood pressure records
• Blood sugar records
• Hospital discharge documents
• Kidney ultrasound or CT reports
• Dialysis records
• Earlier biopsy reports
• Insurance information
• Referral documents
• Written questions

Patients should also record whether swelling, shortness of breath, nausea, itching, or urination changes have developed.

A list of previous creatinine and eGFR results can help the doctor understand whether the change happened gradually or suddenly.

Questions to Ask Dr. Rathi

Patients may consider asking:

• What is causing the change in my kidney function?
• Is the condition temporary or chronic?
• What stage of kidney disease do I have?
• Is protein leaking into my urine?
• Which medicines may affect my kidneys?
• Should any medicine dosage be changed?
• How often should blood and urine tests be repeated?
• Should I limit sodium, potassium, or phosphate?
• Is a kidney biopsy necessary?
• How can further kidney damage be slowed?
• When should dialysis planning begin?
• Which dialysis method may suit my needs?
• Should I be referred for transplant evaluation?
• Which symptoms require urgent attention?
• When should I return for follow-up?

Patients should ask for written instructions when the plan includes medication changes, dietary limits, laboratory testing, or fluid restrictions.
