Kidney Health: Early Warning Signs, Prevention & Treatment, Expert Insights from Jaslok Hospital

| 22 June 2026

India is the diabetes capital of the world — and with that title comes a rapidly rising risk of kidney disease. Yet most patients only seek help when significant damage has already been done. Dr. M.M. Bahadur, Senior Nephrologist with nearly 40 years of experience at Jaslok Hospital, sat down with us to share everything you need to know about protecting your kidneys — from early warning signs to dialysis, transplant, and beyond.

 

What Causes Kidney Failure? The Two Biggest Culprits

According to Dr. Bahadur, diabetes and hypertension together account for approximately 50% of all kidney disease cases in India. The remaining cases stem from:

  • Congenital and genetic kidney diseases
  • Infections
  • ADPKD (Autosomal Dominant Polycystic Kidney Disease)
  • Surgical complications such as kidney stones and obstructive uropathy

The key takeaway: half of all kidney failure cases are potentially preventable through better management of just two conditions — diabetes and high blood pressure.

 

Early Warning Signs of Kidney Disease You Shouldn't Ignore

One of the most dangerous aspects of kidney disease is that 30–35% of patients experience no obvious symptoms until the disease is already advanced. That's why knowing the subtle warning signs is critical.

Common Symptoms

  • Swelling on the face (especially in the morning), legs, or body
  • Breathlessness
  • Nausea and vomiting
  • Fatigue and general weakness

 

Lesser-Known But Important Early Signs

1. Loss of Libido A decrease in sexual drive is an underappreciated early indicator of kidney dysfunction. If your sex life isn't feeling the way it should, consider getting your kidneys checked.

2. Unexplained Weakness If you're experiencing persistent fatigue without a clear cause, kidneys could be the culprit.

3. Nocturia (Increased Urination at Night) If you previously woke up once a night to urinate and now wake up two or three times, this change — called nocturia — is a red flag. Please see a doctor.

"Inexplicable weakness, loss of libido, nocturia — these are early signs of kidney disease that most people miss entirely." — Dr. M.M. Bahadur

 

Diabetes & Kidney Disease: What Diabetics Must Know

Diabetic care is not just about medication. Dr. Bahadur describes it as a tripod: drugs, exercise, and diet. Focusing only on one leg of the tripod makes the whole structure unstable.

 

Beyond Blood Sugar: What Diabetics Should Monitor

  • Urine protein (Microalbuminuria): Get your urine checked every 6 months — not just for glucose, but specifically for micro-protein (microalbumin). This is widely available across India and is one of the earliest signs of kidney damage.
  • Blood pressure: Monitor it regularly.
  • GFR (Glomerular Filtration Rate): Most labs now include GFR with creatinine tests. A GFR dropping from 80 to 60 is a critical signal to intervene — early intervention at this stage can prevent further progression and even allow regression of the disease.
  • Creatinine levels: Check at least once a year or once every two years.

 

Hypertension & Kidney Health: A Dangerous, Underestimated Link

Dr. Bahadur sees a disturbing pattern in his OPD: patients who were diagnosed with hypertension 3–4 years ago, took medication for a while, felt better, and then stopped. By the time they return, their kidneys are in advanced failure.

Hypertension can be primary or secondary — and either way, it silently destroys kidneys.

If you have ever been diagnosed with high blood pressure, the bare minimum is:

  • A routine urine test
  • A GFR (creatinine-based)

These two simple tests can tell you whether your kidneys are being affected. And if there's protein in your urine alongside hypertension, a nephrologist consultation and possibly a kidney biopsy may be necessary to find the root cause.

"Just treating blood pressure symptoms without finding the cause is like giving paracetamol for malaria — it'll never cure the disease."

 

Hydration and Kidney Health: How Much Water Is Actually Enough?

Hydration needs vary based on climate, activity, and individual body weight. Dr. Bahadur breaks it down simply:

  • Normal healthy adult: 2.5 to 3 litres per day in moderate weather
  • Hot climate or heavy exercise: 3.5 to 4 litres (your body loses more through sweat)
  • Air-conditioned environment: You may need less than 2.5 litres

The Golden Formula: Thirst + 500 ml is a good general guideline.

 

Important Caveat for Kidney Patients

Not all kidney diseases require fluid restriction. For example, patients with Chronic Tubulo-Interstitial Nephritis (CTIN) may actually benefit from more water, not less. Always follow your nephrologist's specific advice — there is no one-size-fits-all answer.

 

How Kidney Disease Affects the Whole Body

The body's organs are networked. When kidneys are compromised, every other organ feels the impact.

The most critical connection is with the heart. In fact, Dr. Bahadur reveals a striking statistic:

"Of 10 patients diagnosed with kidney disease, only 1 will end up on dialysis. The rest will die of something else — and most of it is cardiac."

This is why kidney disease patients must also monitor:

  • Lipid profile / cholesterol
  • ECG and cardiac health
  • Blood sugar (even if already on dialysis)
  • Eye health (diabetic retinopathy is a related complication)
  • Brain health

A kidney diagnosis should trigger a holistic body check-up, not just kidney-centric care.

Recommended health check-up frequency: Every 6 months once any kidney issue is diagnosed. Don't delay — medications and dietary advice need constant adjustment as the disease evolves.

 

Understanding Dialysis: Types, Misconceptions & What Patients Get Wrong

Two Main Types of Dialysis

1. Hemodialysis ("Blood Dialysis") A pump circulates blood through a machine with a semipermeable membrane. Impurities pass out, and clean blood returns to the body. This is typically done at a hospital or dialysis centre.

2. CAPD — Chronic Ambulatory Peritoneal Dialysis ("Water Dialysis") A special solution is introduced into the abdomen. The peritoneum (stomach lining) acts as a natural dialyzer. The patient performs this at home. However, it's not recommended for elderly patients with weak eyes or significantly impaired residual kidney function.

Both methods are equally effective — your nephrologist will help you choose based on your condition.

 

Common Misconceptions About Dialysis

Myth 1: Dialysis does all the work. Reality: Dialysis replaces only 10–15% of normal kidney function. The remaining 85–90% must be managed through medications, diet, and lifestyle. Stopping doctor visits after starting dialysis is a critical mistake.

Myth 2: Fewer sessions are okay. Reality: The minimum recommended frequency is 3 sessions per week, 4 hours each. That's just 12 hours per week vs. the 168 hours a normal kidney works. Cutting sessions is medically dangerous.

Myth 3: All dialysis centres are the same. Reality: The quality of water used in hemodialysis makes an enormous difference. Top centres like Jaslok Hospital run closed-loop RO (Reverse Osmosis) systems with monthly bacteriological and chemical testing. Many clinics use basic single-pass RO units — a significant quality gap that affects patient outcomes.

 

Are There Alternatives to Dialysis?

Yes — and they may be better. Dr. Bahadur highlights two key alternatives for patients on the verge of dialysis:

 

1. Pre-emptive Kidney Transplant

If a kidney transplant is inevitable anyway, doing it before starting dialysis leads to:

  • Better long-term graft survival
  • Higher quality of life
  • Avoidance of dialysis-associated complications

 

2. Conservative Management to Delay Dialysis

For select patients, expert nephrological management has been shown to postpone dialysis by up to 4 years — a massive financial and quality-of-life benefit for families.

 

Family History of Kidney Disease? Here's What to Do

If kidney disease, dialysis, or transplant has occurred in your family, you are at elevated risk. Here's a risk breakdown:

  • Both parents diabetic: ~40% chance you will develop diabetes (and potentially kidney disease)
  • Parent had kidney transplant or dialysis: High probability of developing Chronic Kidney Disease (CKD)
  • Family history of ADPKD (Polycystic Kidney Disease): Ultrasound and GFR monitoring even before symptoms appear

Action Plan for High-Risk Individuals:

  • Proactively check blood sugar
  • Check urine for protein
  • Monitor blood pressure
  • Get routine bloodwork (creatinine/GFR) every 6 months

"Don't panic — but don't bury your head in the sand either. There are solutions for every kidney problem today."

 

Tips for Maintaining Kidney Health: What Everyone Should Know

Dr. Bahadur's list of kidney-friendly lifestyle habits:

  • Balanced mixed diet — vegetarian or non-vegetarian is fine, but keep protein in moderation
  • Adequate hydration — context-based (climate, activity, body weight)
  • Regular exercise — cardio is especially kidney-friendly (the kidneys depend on good heart output)
  • Routine health check-ups — every 6 months if you have any risk factor

Avoid NSAIDs and over-the-counter painkillers — even Ayurvedic medications not prescribed by a doctor

  • Avoid excessive protein supplementation — popular among gym-goers, but creatinine (a kidney burden) is the end product of protein metabolism
  • Avoid excess salt and processed/fast food
    Don't smoke — smoking accelerates kidney disease progression, not just lung damage

 

The Most Kidney-Friendly Snack (According to Dr. Bahadur)

Sabudana khichdi with boiled eggs. Sabudana is pure starch (no protein load on kidneys), and eggs provide Grade 1 protein in the right quantity — a near-perfect combination for kidney patients.
