Comprehensive Care for Kidney Health

Nephrology is the medical speciality focused on the diagnosis, treatment, and management of diseases affecting the kidneys and related systems. Healthy kidney function is important for removing waste from the body, maintaining fluid balance, regulating blood pressure, and supporting overall health.

At K & K Super Speciality Hospital, Nephrology care focuses on the early identification and management of kidney-related conditions, monitoring kidney function, controlling associated health problems, and providing appropriate treatment according to each patient's needs.

What is Nephrology?

Nephrology deals with the prevention, diagnosis, and treatment of kidney diseases and conditions that affect kidney function.

A nephrologist may manage conditions involving:

• Kidney function
• Chronic kidney disease
• Acute kidney injury
• Kidney-related blood pressure problems
• Electrolyte and fluid imbalances
• Protein or blood in the urine
• Certain kidney infections
• Kidney failure
• Dialysis-related care

Kidney problems can develop gradually without obvious symptoms, making appropriate medical evaluation important for people at increased risk.

Common Kidney Conditions

Nephrology services may help manage conditions such as:

• Chronic kidney disease
• Acute kidney injury
• Kidney failure
• Proteinuria
• Blood in the urine
• Electrolyte abnormalities
• Fluid retention
• High blood pressure associated with kidney disease
• Certain kidney infections
• Diabetic kidney disease
• Kidney disease related to other medical conditions

Treatment depends on the underlying cause, severity of kidney impairment, and the patient's overall health.

Chronic Kidney Disease

Chronic kidney disease (CKD) occurs when kidney function is reduced or kidney damage persists over time.

Common risk factors include:

• Diabetes
• High blood pressure
• Cardiovascular disease
• Certain inherited kidney conditions
• Recurrent kidney problems
• Long-term use of certain medicines
• Other medical conditions affecting the kidneys

Early-stage kidney disease may cause few or no noticeable symptoms. Regular testing can therefore be important for people at higher risk.

Symptoms of Kidney Problems

Kidney disease does not always cause symptoms in its early stages.

When symptoms occur, they may include:

• Swelling of the feet, ankles, or face
• Changes in urination
• Foamy urine
• Blood in the urine
• Fatigue
• Nausea
• Reduced appetite
• Itching
• Breathlessness due to fluid accumulation
• Changes in blood pressure

Persistent or unexplained symptoms should be medically evaluated.

Acute Kidney Injury

Acute kidney injury (AKI) is a sudden reduction in kidney function that can develop over a short period.

Possible causes include:

• Severe dehydration
• Serious infections
• Low blood pressure
• Certain medicines
• Urinary obstruction
• Other acute medical conditions

AKI can require prompt medical assessment and treatment. In some cases, temporary dialysis may be required depending on the severity and cause.

Diabetic Kidney Disease

Diabetes can affect the small blood vessels in the kidneys and may gradually reduce kidney function.

Regular monitoring may include:

• Blood glucose levels
• Serum creatinine
• Estimated kidney function
• Urine protein or albumin testing
• Blood pressure monitoring

Good diabetes and blood pressure management can help reduce the risk of kidney complications.

High Blood Pressure and Kidney Health

The kidneys and blood pressure are closely connected.

High blood pressure can contribute to kidney damage, while kidney disease can also cause or worsen high blood pressure.

Managing blood pressure is therefore an important part of protecting kidney function.

Patients with kidney disease may require regular monitoring of:

• Blood pressure
• Kidney function
• Electrolytes
• Urine protein
• Medication response

Kidney Function Tests

Kidney function can be assessed using blood and urine tests.

Common investigations may include:

• Serum creatinine
• Estimated glomerular filtration rate (eGFR)
• Blood urea
• Electrolyte testing
• Urine routine examination
• Urine protein or albumin testing
• Other investigations based on clinical requirements

The results are interpreted together with the patient's medical history and examination findings.

Protein in the Urine

Protein in the urine, also known as proteinuria, can sometimes indicate kidney damage.

It may occur due to:

• Diabetes
• High blood pressure
• Kidney inflammation
• Other kidney conditions
• Certain temporary medical conditions

Persistent protein in the urine should be evaluated to determine the underlying cause.

Blood in the Urine

Blood in the urine can have several possible causes, including urinary infections, kidney stones, kidney disease, or other urinary tract conditions.

A medical evaluation may include urine testing, blood tests, imaging, or specialist assessment depending on the clinical situation.

Unexplained or persistent blood in the urine should not be ignored.

Electrolyte and Fluid Imbalance

The kidneys help regulate important substances such as sodium, potassium, and other electrolytes while maintaining fluid balance.

Kidney problems can lead to abnormal electrolyte levels or fluid retention.

Treatment may involve:

• Medicines
• Dietary adjustments
• Fluid management
• Treatment of the underlying kidney condition
• Regular blood testing

The treatment approach depends on the specific abnormality and its cause.

Kidney Disease and Dialysis

When kidney function becomes severely reduced, the kidneys may no longer be able to adequately remove waste and excess fluid from the body.

Dialysis may be required in certain patients with advanced kidney failure or severe acute kidney injury.

The two main forms of dialysis are:

• Haemodialysis
• Peritoneal dialysis

The appropriate treatment depends on the patient's kidney function, medical condition, and overall circumstances.

Haemodialysis

Haemodialysis uses a dialysis machine and filter to remove waste products and excess fluid from the blood.

Patients requiring regular haemodialysis generally need an appropriate vascular access, such as an arteriovenous fistula, graft, or catheter, depending on their circumstances.

During treatment, patients are monitored for changes in:

• Blood pressure
• Fluid balance
• Electrolytes
• Symptoms
• Overall clinical condition

Kidney Disease and Diet

Nutrition can play an important role in the management of kidney disease.

Depending on kidney function and other medical conditions, patients may receive guidance regarding:

• Salt intake
• Fluid intake
• Protein intake
• Potassium
• Phosphorus
• Overall calorie and nutritional requirements

Dietary recommendations should be individualised rather than followed without medical or nutritional guidance.

Medication and Kidney Health

Some medicines can affect kidney function or may require dose adjustments when kidney function is reduced.

Patients with kidney disease should inform their doctor about all:

• Prescription medicines
• Over-the-counter medicines
• Painkillers
• Supplements
• Herbal products

Do not start or stop medicines without appropriate medical advice.

Kidney Disease in Older Adults

Kidney function can naturally change with age, while older adults may also have conditions such as diabetes, high blood pressure, or heart disease that increase the risk of kidney problems.

Older patients may benefit from regular monitoring of:

• Kidney function
• Blood pressure
• Blood sugar
• Electrolytes
• Medication requirements

Treatment is planned according to the patient's overall health and individual needs.

Preventing Kidney Problems

Some kidney conditions cannot be prevented, but several measures can help support kidney health.

These include:

• Managing diabetes
• Controlling blood pressure
• Maintaining a healthy weight
• Staying appropriately hydrated
• Avoiding unnecessary use of certain pain medicines
• Following prescribed treatment
• Regular kidney function testing when recommended
• Avoiding smoking

People with diabetes, hypertension, or a family history of kidney disease may benefit from regular medical monitoring.

When Should You Consult a Nephrologist?

A nephrology consultation may be recommended if you have:

• Abnormal kidney function tests
• Persistent protein in the urine
• Blood in the urine without a clear cause
• Swelling of the legs or face
• Recurrent electrolyte abnormalities
• Uncontrolled high blood pressure
• Reduced kidney function
• Chronic kidney disease
• Recurrent or unexplained kidney-related problems
• Symptoms suggesting advanced kidney disease

Early evaluation can help identify kidney problems and support appropriate long-term management.

Nephrology and Kidney Disease Monitoring

Patients with chronic kidney disease may require regular follow-up to monitor changes in kidney function and related health conditions.

Follow-up may include:

• Blood tests
• Urine tests
• Blood pressure monitoring
• Electrolyte assessment
• Medication review
• Dietary guidance
• Monitoring for complications

The frequency of follow-up depends on the severity and progression of the condition.
