Understanding Kidney Failure and Why Dialysis Is Needed

Kidneys are small, bean-shaped organs, yet they play a powerful role in keeping the body healthy. They filter out toxins, balance fluids, and maintain essential minerals in our blood. When these organs stop working properly, the condition is called kidney failure or end-stage renal disease (ESRD). Without proper treatment, kidney failure can lead to life-threatening complications. One of the most common and effective treatments for advanced kidney failure is dialysis.

In this blog, we will explore what kidney failure is, its causes, symptoms, and why dialysis becomes a necessity for many patients.

What Is Kidney Failure?

Kidney failure occurs when the kidneys lose their ability to filter waste products and excess fluids from the blood. This leads to a buildup of harmful toxins in the body, which can affect almost every organ.

There are two types of kidney failure:

Acute Kidney Failure (AKF) – A sudden loss of kidney function, usually over a few hours or days. It can be caused by severe dehydration, infections, or certain medications. If treated promptly, kidney function may return to normal.
Chronic Kidney Failure (CKF) – A gradual loss of kidney function over months or years. This is often irreversible and requires long-term management.

Causes of Kidney Failure

Several medical conditions and lifestyle factors can lead to kidney failure. The most common causes include:

Diabetes – High blood sugar damages the blood vessels in the kidneys.
High Blood Pressure (Hypertension) – Increased pressure damages kidney tissues over time.
Glomerulonephritis – Inflammation of the kidney’s filtering units.
Polycystic Kidney Disease – A genetic condition causing cyst growth in kidneys.
Prolonged Obstruction – Conditions like kidney stones, tumors, or enlarged prostate can block urine flow.
Recurrent Kidney Infections – Untreated infections can cause permanent kidney damage.

Symptoms of Kidney Failure

Kidney failure may not show symptoms in the early stages, but as the condition progresses, the following signs become noticeable:

Persistent fatigue and weakness
Swelling in the ankles, feet, or face due to fluid retention
Shortness of breath
Nausea, vomiting, and loss of appetite
Reduced urine output or complete absence of urine
Muscle cramps and persistent itching
Confusion or difficulty concentrating

If you experience these symptoms, it is important to seek medical advice immediately from specialists like those at Sarvesh Health City – Best Nephrology Hospital in Hisar for early diagnosis and treatment.

How Kidney Failure Is Diagnosed

Doctors use a combination of tests to determine the extent of kidney damage:

Blood Tests – Measures creatinine and urea levels to assess kidney function.
Urine Tests – Detects protein, blood, or other abnormalities.
Ultrasound or CT Scan – Checks kidney size, structure, and presence of blockages.
Kidney Biopsy – Examines tissue samples for signs of damage or disease.

Treatment Options for Kidney Failure

Treatment depends on the cause, stage, and overall health of the patient. In early stages, controlling blood pressure, blood sugar, and following a kidney-friendly diet can slow down damage.

However, when the kidneys lose about 85–90% of their function, they can no longer sustain life without intervention. At this stage, two main treatments are available:

Dialysis
Kidney Transplant

What Is Dialysis and Why Is It Needed?

Dialysis is a medical process that removes waste products, excess fluids, and toxins from the blood when the kidneys can no longer perform this function naturally.

Without dialysis or a kidney transplant, toxins will accumulate in the body, leading to:

Heart failure
Severe electrolyte imbalances
Fluid overload in the lungs
Life-threatening complications

Simply put: Dialysis acts as an artificial kidney.

Types of Dialysis

There are two main types of dialysis, and the choice depends on the patient’s condition, lifestyle, and medical advice.

1. Hemodialysis

Process: Blood is taken out of the body through a machine called a dialyzer (artificial kidney) which cleans it before returning it to the body.
Frequency: Usually three times a week, each session lasting 3–5 hours.
Where: Can be done at a hospital or dialysis center, such as Sarvesh Health City – Best Nephrology Hospital in Hisar.

Advantages:

Efficient at removing waste and fluid.
Done under medical supervision.

Disadvantages:

Requires regular visits to a dialysis center.
Some diet and fluid restrictions.

2. Peritoneal Dialysis

Process: Uses the lining of your abdomen (peritoneum) to filter the blood inside your body. A cleansing fluid is introduced into the abdominal cavity and later drained out.
Frequency: Usually performed daily at home, either manually or using a machine overnight.

Advantages:

Can be done at home, offering flexibility.
Fewer dietary restrictions compared to hemodialysis.

Disadvantages:

Risk of infection in the abdominal lining.
Requires commitment and proper training.

When Should Dialysis Begin?

Dialysis is usually started when:

Kidney function drops below 15% of normal capacity.
Severe symptoms like swelling, shortness of breath, nausea, or fatigue appear.
Blood tests show dangerously high levels of waste products like creatinine and urea.

Your nephrologist will determine the right time to start dialysis, ensuring it is neither too early (to avoid unnecessary burden) nor too late (to prevent serious complications).

Living with Dialysis

While dialysis requires adjustments in lifestyle, many patients continue to live active and fulfilling lives. Some key tips include:

Follow a kidney-friendly diet – Limit salt, potassium, phosphorus, and fluids.
Take prescribed medications regularly to control blood pressure and prevent complications.
Maintain hygiene to avoid infections, especially for dialysis access sites.
Stay active with light exercises, as recommended by your doctor.
Seek emotional support – Joining patient support groups can be very helpful.

Role of a Specialized Nephrology Hospital

Kidney failure is a complex condition that needs expert care. Choosing a facility with experienced nephrologists, advanced dialysis units, and comprehensive patient care can make a big difference.

Can Kidney Failure Be Prevented?

While some causes of kidney failure, like genetic disorders, can’t be prevented, many risk factors can be managed:

Control diabetes and high blood pressure.
Maintain a healthy weight.
Drink adequate water.
Avoid excessive use of painkillers and harmful medications.
Get regular kidney function tests if you have risk factors.

Final Thoughts

Kidney failure is a serious condition, but with timely diagnosis and the right treatment plan, patients can still lead healthy and productive lives. Dialysis, though life-changing, offers a chance to manage kidney failure effectively until a transplant becomes possible.
