CKD

What Is Chronic Kidney Disease? A Complete Guide

Chronic Kidney Disease (CKD) is a long-term condition where the kidneys gradually lose their ability to filter waste from the blood. Learn about the five stages, warning signs, and what you can do to slow progression.

Diet & Nutrition

The Kidney-Friendly Diet: What to Eat and Avoid

Diet plays a crucial role in managing kidney disease. Discover which foods support kidney health, which to limit, and practical tips for building a renal-friendly meal plan.

Dialysis

Hemodialysis Explained: What to Expect

Starting dialysis can feel overwhelming. This guide walks you through how hemodialysis works, what a typical session looks like, and how to prepare for life on dialysis.

The 5 Stages of CKD

CKD is classified into five stages based on your estimated Glomerular Filtration Rate (eGFR) - a measure of how well your kidneys are filtering blood.

Stage 1

eGFR ≥ 90
Normal or High
Kidney function is normal or near-normal, but signs of kidney damage (e.g. protein in urine) are present. Lifestyle changes and monitoring are key.

Stage 2

eGFR 60–89
Mildly Decreased
Mild reduction in kidney function. Most people have no symptoms. Regular monitoring and managing risk factors like blood pressure and diabetes is important.

Stage 3

eGFR 30–59
Moderately Decreased
Moderate loss of kidney function. Symptoms such as fatigue, swelling, and changes in urination may begin. Specialist nephrology care is recommended.

Stage 4

eGFR 15–29
Severely Decreased
Severe reduction in kidney function. Planning for kidney replacement therapy (dialysis or transplant) should begin. Close specialist monitoring is essential.

Stage 5

eGFR < 15
Kidney Failure
End-stage kidney disease. The kidneys can no longer sustain life without support. Dialysis or a kidney transplant is required.
eGFR = estimated Glomerular Filtration Rate, measured in mL/min/1.73m². Ask your doctor about your eGFR at your next visit.

Kidney-Friendly Diet Tips

Small dietary changes can make a significant difference in slowing kidney disease progression.

Limit Sodium

Reduce salt intake to help control blood pressure and reduce fluid retention. Aim for less than 2,000 mg of sodium per day. Avoid processed foods, pickles, and papadums.

Monitor Potassium

In later stages of CKD, potassium can build up in the blood. Limit high-potassium foods like bananas, oranges, potatoes, and tomatoes if advised by your doctor.

Control Phosphorus

High phosphorus weakens bones and damages blood vessels. Avoid cola drinks, processed meats, and dairy in excess. Your doctor may prescribe phosphate binders.

Manage Protein Intake

A moderate protein diet can reduce the workload on your kidneys. Avoid excessive protein supplements. Your nephrologist will advise the right amount for your stage.

Stay Hydrated (Wisely)

Fluid needs vary by stage and whether you are on dialysis. Some patients need to restrict fluids. Always follow your nephrologist's guidance on fluid intake.

Choose Kidney-Friendly Foods

Good options include white rice, chapati, cabbage, cauliflower, apples, and egg whites. A renal dietitian can help build a personalised meal plan.

Important: Dietary needs vary significantly depending on your CKD stage, other health conditions, and medications. Always follow the dietary guidance given by your nephrologist or renal dietitian. Do not make major dietary changes without consulting your care team.

Warning Signs of Kidney Disease

Kidney disease is often called a "silent disease" because symptoms appear late. Know the signs and seek evaluation early.

  • Swelling in feet, ankles, or face
  • Persistent fatigue or weakness
  • Changes in urine — foamy, dark, or reduced output
  • High blood pressure that is difficult to control
  • Nausea, vomiting, or loss of appetite
  • Shortness of breath or difficulty breathing
  • Muscle cramps, especially at night
  • Itching or dry skin

Who Is at Risk?

Certain conditions significantly increase the risk of developing kidney disease. If any of the following apply to you, regular kidney function screening is strongly recommended.

  • Diabetes (Type 1 or Type 2)
  • High blood pressure (Hypertension)
  • Family history of kidney disease
  • Recurrent kidney stones or UTIs
  • Obesity or metabolic syndrome
  • Age above 60 years
  • Long-term use of painkillers (NSAIDs)

Frequently Asked Questions

Chronic Kidney Disease usually cannot be completely cured, but early diagnosis and proper treatment can slow or even stop its progression. Regular follow-ups, medication, diet, and lifestyle changes are essential.

The frequency depends on your kidney condition. Early-stage CKD patients may need reviews every 3–6 months, while advanced disease requires more frequent visits.

Dialysis itself is generally not painful. Some patients experience mild discomfort during needle insertion or temporary fatigue after treatment.

Yes. Diabetes is one of the leading causes of Chronic Kidney Disease. Good blood sugar control significantly reduces the risk of kidney damage.

Common tests include Serum Creatinine, eGFR, Urine Albumin, Urine Routine Examination, Blood Pressure monitoring, and Kidney Ultrasound.

Yes. With proper planning, many dialysis centres across India and internationally accept visiting patients. Inform your nephrologist in advance to arrange dialysis and prepare the necessary medical documents.
