By The Time You Feel Kidney Failure, 90% Is Gone

Kidney failure almost never announces itself in time. Dr Visweswar Reddy, senior consultant nephrologist at SRM Prime Hospital, told The Week in March 2026 that the familiar warning signs — frothy urine, swelling in the feet, loss of appetite, vomiting, a tiredness that won't lift — usually turn up only after more than 90 per cent of kidney function has already been destroyed. Everything before that stage is silent.

That silence is why the numbers keep climbing. India carried an estimated 13.8 crore chronic kidney disease cases in 2023, second in the world only to China's 15.2 crore, with more than 1.2 lakh deaths in that year alone. An earlier Global Burden of Disease estimate for 2021 put the figure at 9.3 per cent of the population — around 128 million people — and 175,637 deaths. The methods differ; the direction doesn't.

Here's the part that should make you book a blood test. Roughly 2.2 lakh Indians reach end-stage renal disease every year, generating demand for about 3.4 crore dialysis sessions annually. In the government's own costing for the Pradhan Mantri National Dialysis Programme, each session carries an added expenditure of about ₹2,000. Do that maths on thrice-weekly dialysis and you're looking at a household budget rearranged around one organ.

Why Kidney Failure Hides For So Long

Kidneys are over-engineered. You can lose a large share of filtering capacity and still produce normal-looking urine, feel fine, and pass a routine health check that doesn't specifically look for it. The organ compensates until it can't. By the stage most people notice something is wrong, the conversation with the doctor is no longer about prevention — it's about slowing the slide.

Most of these symptoms appear only when more than 90 per cent of kidney function has already been lost.

The two biggest drivers are boringly familiar. Dr Reddy noted that around 40 per cent of people with diabetes and 40 per cent of those with long-standing high blood pressure may eventually develop chronic kidney disease. Doctors quoted by The Federal estimate that simply controlling diabetes and hypertension properly could cut CKD prevalence by about 15 per cent. That is a huge return for unglamorous work.

The Habits Worth Stopping This Week

Nephrologists tend to be blunt about this list, partly because so much of it is self-inflicted and reversible. None of it requires a gym membership or an expensive app.

Reaching For A Painkiller Every Time Something Aches

Kidney specialists interviewed by HuffPost said they personally avoid routine over-the-counter NSAIDs — ibuprofen, naproxen and their cousins — especially when taken regularly over long stretches for chronic pain. An occasional tablet is not the danger. The daily strip bought loose from the chemist for a knee that's hurt for three years is. Ask a doctor for an alternative instead of self-prescribing indefinitely.

Salt You Never Actually Taste

The WHO ceiling is roughly 5 grams of salt a day, and Indian clinicians often push for under 2 grams of sodium. Most of it isn't from the salt shaker — it's in pickles, papad, namkeen, instant noodles, bread, restaurant gravies and packaged masala mixes. Excess sodium drives fluid retention and blood pressure, and blood pressure is what grinds down the kidney's filters.

Protein Powders And Unlabelled 'Kidney Tonics'

High-dose supplements taken chronically can strain the kidneys, and unregulated herbal preparations sold for "kidney cleansing" are a recurring cause of injury in Indian nephrology wards. Anything you swallow daily deserves the same scrutiny as a prescription drug.

What To Start Doing Instead

Aim for around 2.5 litres of water a day unless a doctor has told you to restrict fluids. Cut cooking oil. Get the weight down, because obesity adds mechanical and metabolic load. Stop smoking — it damages the small blood vessels the kidney depends on entirely. And take your BP and sugar medicines every single day, not just when you feel unwell; missed doses are one of the quietest causes of accelerating damage.

Two Cheap Tests That Catch It Early

You do not need a specialist to start. A serum creatinine blood test and a urine test for protein will flag most early damage, and both are available at neighbourhood labs across India for a few hundred rupees — often bundled into diabetes panels you may already be doing. Add a random blood sugar check. If you have diabetes, hypertension, obesity or a family history of kidney disease, treat this as an annual ritual.

What The State Actually Covers

The Pradhan Mantri National Dialysis Programme, running since 2016-17, provides free dialysis to below-poverty-line patients at district hospitals, and has expanded to around 1,704 centres across 751 districts. That is real coverage, but it kicks in at the worst possible moment — after the kidneys are gone. Ayushman Bharat can absorb some costs too. Neither replaces a ₹300 test taken five years earlier.

So pick one thing this week. Book a creatinine and urine protein test if you're over 40 or in any risk group, and take the report to a doctor even if the numbers look normal — a baseline is worth having. Then look honestly at the painkiller strip in your drawer and the salt hiding in your snacks. Kidney failure is one of the few catastrophic illnesses where the early work is this cheap and this dull.
