She Lost Both Kidneys Before 30: 2 Everyday Habits That Can Increase the Risk of Kidney Failure

The kidneys are small organs, but they perform an enormous amount of work every day.

They filter waste products from the blood, regulate fluid levels, help control blood pressure, maintain electrolyte balance, and contribute to the production of hormones involved in red blood cell production and bone health.

Because kidney disease can progress quietly, a person may lose a significant amount of kidney function without feeling seriously ill at first.

That is why the dramatic message in the image—warning that two common habits can cause kidney failure—deserves a closer look.

There isn't a universal pair of habits that will inevitably cause someone to “lose both kidneys.” Kidney failure usually develops through multiple factors, including diabetes, high blood pressure, inherited kidney disorders, autoimmune disease, infections, certain medications or toxins, and other medical conditions.

However, some everyday behaviors can increase kidney stress or contribute to conditions that damage the kidneys over time.

Here are two particularly important ones.

1. Consistently Drinking Too Little Water

Hydration is important for normal kidney function.

Your kidneys need adequate fluid to help remove waste products through urine. When someone becomes severely dehydrated, blood flow to the kidneys can fall, potentially causing acute kidney injury (AKI).

Occasional mild dehydration usually does not cause permanent kidney failure in an otherwise healthy person.

The concern is severe, prolonged, or repeated dehydration, particularly in people who already have kidney disease or other health problems.

Dehydration can happen because of:

• Heavy sweating
• Prolonged vomiting
• Severe diarrhea
• Fever
• Excessive heat exposure
• Not having access to enough fluids
• Certain medications or medical conditions

People who work outdoors, exercise intensely, or live in very hot climates may need to pay particular attention to fluid intake.

But there's an important caveat:

More water isn't always better.

People with advanced kidney disease, heart failure, or certain other medical conditions may actually need to restrict fluid intake according to their clinician's instructions.

So the goal isn't to force yourself to drink enormous quantities of water.

The goal is appropriate hydration for your individual health situation.

2. Regularly Using Painkillers Without Medical Guidance

This is a much more important issue than many people realize.

Certain common pain medications, particularly nonsteroidal anti-inflammatory drugs (NSAIDs), can affect kidney function.

Examples include:

• Ibuprofen
• Naproxen
• Diclofenac
• Other NSAIDs

These medicines can be very useful when taken appropriately.

But frequent or prolonged use—especially at high doses—can increase the risk of kidney problems.

The risk becomes greater in people who are:

Dehydrated

Older

Living with chronic kidney disease

Taking certain blood-pressure medications or diuretics

Living with heart failure

Taking NSAIDs at high doses or for prolonged periods

NSAIDs reduce production of certain prostaglandins that help maintain blood flow to the kidneys under some circumstances.

In vulnerable people, this can contribute to acute kidney injury.

That doesn't mean you should panic if you've taken ibuprofen once or twice.

It means you should avoid using painkillers continuously without understanding the risks.

If you regularly need pain medication, talk with a healthcare professional about the safest option for you.

Kidney Failure Usually Doesn't Happen Overnight

One of the biggest misconceptions surrounding kidney disease is that someone can suddenly “lose both kidneys” simply because of one unhealthy habit.

In reality, chronic kidney disease generally develops over months or years, although certain severe conditions can cause acute kidney injury much more quickly.

Some of the leading causes of chronic kidney disease include:

Diabetes

High blood glucose over time can damage the tiny blood vessels and filtering structures inside the kidneys.

High blood pressure

Persistent hypertension can damage kidney blood vessels and gradually reduce kidney function.

Glomerular diseases

Conditions affecting the kidney's filtering units can cause inflammation and progressive damage.

Inherited disorders

Some genetic diseases, such as polycystic kidney disease, can gradually impair kidney function.

Repeated kidney injury

Certain infections, medications, toxins, or severe dehydration can cause kidney injury, particularly when risk factors are already present.

The Kidneys Can Be Damaged Without Obvious Symptoms

This is why kidney disease is sometimes called a “silent” condition.

A person can have reduced kidney function without experiencing severe pain.

Early kidney disease may produce few or no noticeable symptoms.

As kidney function becomes more severely impaired, symptoms can include:

• Swelling in the legs or ankles
• Fatigue
• Nausea
• Reduced appetite
• Changes in urination
• Foamy urine
• Itching
• Muscle cramps
• Difficulty concentrating
• Shortness of breath

These symptoms are not specific to kidney disease, but unexplained or persistent symptoms should be evaluated.

Foamy Urine Can Be a Clue

Occasionally seeing bubbles in the toilet isn't necessarily a problem.

However, persistent foamy or frothy urine can sometimes indicate excess protein in the urine.

Proteinuria may occur when the kidney's filtering system is damaged.

This is particularly important in people with:

Diabetes

High blood pressure

Known kidney disease

A family history of kidney problems

A simple urine test can help determine whether significant protein is present.

Swelling May Also Deserve Attention

When the kidneys aren't functioning properly, the body may retain excess salt and fluid.

This can contribute to swelling, particularly around the:

Feet

Ankles

Lower legs

Sometimes swelling around the eyes can also occur.

However, swelling has many possible causes, including heart disease, liver disease, medications, venous problems, and other conditions.

So swelling should not automatically be interpreted as kidney failure.

Be Careful With Supplements and “Detox” Products

Another overlooked kidney risk is the assumption that natural automatically means safe.

Some herbal products and supplements can contain compounds that affect the kidneys or interact with medications.

Products marketed as:

“Kidney cleanses”

“Detox teas”

“Natural diuretics”

“Heavy-metal cleanses”

may not have the safety profile implied by their marketing.

Some supplements can also contain contaminants or ingredients that aren't clearly disclosed.

Your kidneys already perform the body's filtration work.

You don't need a commercial “kidney detox” to make them clean.

What About Salt?

Excess sodium is another dietary issue worth addressing.

Eating too much sodium can contribute to high blood pressure, one of the major causes of chronic kidney damage.

Processed foods are often major sources of sodium.

Common examples include:

• Processed meats
• Instant noodles
• Packaged soups
• Salty snacks
• Fast food
• Some sauces and prepared meals

Reducing excessive sodium intake can support blood-pressure control and cardiovascular health.

You don't have to eliminate salt completely.

The goal is to avoid consistently consuming excessive amounts.

How Can You Protect Your Kidneys?

The best kidney-protection strategy isn't a single miracle food or drink.

It's a collection of everyday habits.

Keep blood pressure under control

High blood pressure is one of the most important modifiable kidney-disease risk factors.

Manage blood glucose

If you have diabetes, keeping blood glucose within your target range can help reduce long-term kidney complications.

Stay appropriately hydrated

Drink according to your body's needs and your healthcare professional's advice.

Avoid unnecessary NSAID use

Don't routinely take high doses or use them for prolonged periods without medical guidance.

Limit excessive sodium

Choose more minimally processed foods and check nutrition labels.

Don't smoke

Smoking damages blood vessels and increases cardiovascular and kidney risks.

Maintain a healthy weight and stay active

Regular physical activity supports blood pressure, metabolic health, and cardiovascular function.

Simple Tests Can Detect Kidney Problems Early

If you're concerned about your kidneys, you don't have to wait for obvious symptoms.

Doctors can assess kidney health with relatively simple tests.

Blood creatinine and eGFR

Creatinine is used to estimate how efficiently the kidneys filter blood.

The estimated glomerular filtration rate (eGFR) provides an important measure of kidney function.

Urine albumin-to-creatinine ratio

This test can detect abnormal amounts of albumin in the urine.

Together, these tests can reveal kidney problems before severe symptoms develop.

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

The Bottom Line

The claim that two simple habits will inevitably cause someone to lose both kidneys is far too simplistic.

But there are genuine kidney risks worth taking seriously.

Severe or repeated dehydration can contribute to kidney injury.

Frequent or inappropriate use of NSAID painkillers can damage kidney function, particularly in vulnerable people.

And beyond those two habits, some of the biggest threats to long-term kidney health are high blood pressure and diabetes.

Your kidneys don't need extreme cleanses or miracle supplements.

They need consistent protection through good blood-pressure and blood-sugar control, appropriate hydration, sensible medication use, healthy nutrition, physical activity, and regular medical monitoring when risk factors are present.

If you have persistent swelling, major changes in urination, unexplained fatigue, nausea, or other concerning symptoms—or if you already have diabetes, high blood pressure, or kidney disease—talk with a healthcare professional and consider appropriate kidney testing.

Protecting your kidneys isn't about one perfect habit. It's about the choices you repeat every day.
