7 Habits That Cause Kidney Failure or Chronic Kidney Disease

Most people don’t think twice about popping a pain pill for a headache or grabbing a protein bar on the go. The truth is that many seemingly innocent everyday choices are actually habits that cause kidney disease, secretly inflicting kidney damage over time.  With over 35 million Americans living with kidney diseases, understanding the impact of our common habits is more critical than ever. Untreated chronic kidney disease (CKD) can eventually lead to dialysis or the need for a transplant, a reality most of us want to avoid.

The frightening part is that many habits perceived as "healthy" can be harmful. This article is designed to bring clarity and help you protect your long-term kidney health. My analysis, based on extensive clinical experience, identifies seven common, yet horrible, habits that can lead to kidney failure. By understanding these risks, you can take proactive steps to preserve your kidney function and overall well-being.

7 Habits That Can Cause Kidney Failure or Chronic Kidney Disease

Your kidneys are vital organs, located in your lower back, that work tirelessly as your body's master filtration system. They filter your blood to remove waste, toxins, and excess fluid. Beyond that, they play a huge role in regulating blood pressure, maintaining good bone health, producing red blood cells, and balancing vitamin D levels.

Knowing this, most people try to protect their kidneys. However, in my experience as a board-certified kidney doctor, we see patients daily whose well-intentioned habits have inadvertently led them to my office with kidney damage. The following seven habits are among the most common culprits we see that can seriously compromise your renal health.

1. Abusing Over-the-Counter Pain Relievers (NSAIDs)

One of the most common habits that can damage your kidneys is the frequent use of over-the-counter (OTC) pain medications, specifically Nonsteroidal Anti-Inflammatory Drugs (NSAIDs). This category includes popular drugs like ibuprofen (Advil, Motrin) and naproxen (Aleve). While effective for occasional pain and inflammation, the problem arises from overuse or taking them above the recommended dose or for prolonged periods.

The risk of kidney failure from NSAIDs is significantly higher if you already have compromised kidney function or other risk factors like diabetes and high blood pressure. These drugs work by constricting the blood vessels that supply the kidneys, which reduces blood flow and oxygen. Over time, this can lead to severe kidney damage, a condition known as NSAID nephropathy. In some cases, I have seen patients require dialysis solely from overusing these common pain relievers for conditions like chronic arthritis or migraines.

Actionable Takeaway: If you have healthy kidneys, only use NSAIDs occasionally and always follow the label's directions. If you have existing kidney disease or are at high risk, consult your doctor about safer alternatives like acetaminophen (Tylenol). Other non-medical options include physical therapy, acupuncture, or hot/cold compresses to manage the pain.

2. Dehydration or Extreme Over-Hydration (drinking too much water)

Proper hydration is a delicate balance, and extremes in either direction can be dangerous for your kidney health. Dehydration is a surprisingly common habit that can cause acute kidney damage. When you don't drink enough water, the blood flow and oxygen to your kidneys decrease, impairing their ability to function. This condition, known as pre-renal azotemia, can become so severe that it requires dialysis to correct. This is a particular risk for the elderly, who may have a diminished sense of thirst, and even for young, healthy athletes who lose significant fluids during intense exercise. Not drinking enough water can also increase your risk for painful kidney stones.

On the flip side, extreme over-hydration can also be fatal. Drinking excessive amounts of water faster than your kidneys can process it dilutes the sodium in your blood, a condition called hyponatremia. This can lead to brain swelling (cerebral edema), seizures, and even death.

Actionable Takeaway: For most healthy adults, a good target is two to three liters of water per day (about four to six 16-ounce bottles). You can also hydrate with water-rich foods like cucumbers, watermelon, and oranges. Let your urine be your guide: it should be a pale yellow color. If it's dark amber, you're likely dehydrated.

3. Ignoring or Not Managing High Blood Pressure

Ignoring high blood pressure is a horrible habit that is the second leading cause of kidney disease and dialysis in the United States. When your blood pressure is consistently high, it causes the blood vessels throughout your body, including those in your kidneys, to constrict and tighten. Over time, this sustained pressure damages the delicate filtering units in the kidneys, leading to poor circulation and a gradual loss of kidney function (a condition called hypertensive nephrosclerosis).

A common and dangerous belief is that if you don't feel symptoms, your high blood pressure isn't a problem. However, high blood pressure is often called the "silent killer" for this very reason. Ignoring it puts you at high risk for not only kidney diseases but also heart disease and stroke.

Actionable Takeaway: Monitor your blood pressure at home to get an accurate reading away from the stress of a doctor's office. Work with your physician to manage it, limit your sodium intake to no more than 1.5 grams per day, and exercise regularly. Managing your blood pressure is one of the most effective ways to prevent kidney damage and heart disease.

4. Following an Unsupervised High-Protein Diet

High-protein diets are incredibly popular, especially in the fitness and bodybuilding communities. While they can be effective for building muscle mass, they pose a significant risk if you have underlying kidney issues. When you consume protein, it breaks down into waste products that your kidneys must filter from the blood. The more protein you eat, the harder your kidneys have to work.

If you have existing chronic kidney disease, diabetes and high blood pressure, or other risk factors, forcing your kidneys to work overtime with a high-protein diet can accelerate kidney damage. This is a habit that can push already vulnerable kidneys toward failure.

Actionable Takeaway: Before starting a high-protein diet, consult with your doctor to get a more clear picture of your kidney health. Ask for tests that measure your kidney function, such as eGFR, BUN, and creatinine. If your function is impaired, ask for a referral to a registered dietitian who can help you determine a safe amount of protein for your specific needs.

5. Relying Heavily on Processed "Healthy Foods"

This habit is particularly hard to quit because it preys on our best intentions. Many people trying to live a healthier lifestyle rely on convenient, pre-packaged foods marketed as "healthy," such as veggie burgers, frozen vegetarian meals, protein bars, and veggie chips. The problem is that these are often ultra-processed food products loaded with hidden dangers.

For example, just two small vegan sausages can contain over 300 milligrams of sodium, a significant portion of the recommended daily limit. Many "healthy" snacks and bars are also packed with phosphorus and sugar. High sugar intake is a major risk factor for diabetes, which is the number one cause of kidney disease. A diet high in processed food, even the "healthy" kind, can increase your risk for high blood pressure and heart disease, both of which are directly linked to poor kidney health.

Actionable Takeaway: Become a vigilant label-watcher. Avoid foods with high sodium, phosphorus, and sugar content. Prioritize cooking at home with whole foods like fresh fruits, vegetables, and lean proteins. Meal prepping can help you avoid the temptation of grabbing a convenient but unhealthy processed item when you're busy.

6. Overdoing It with "Kidney Cleanses" and Detoxes

The market is flooded with products promising to "cleanse" or "detox" your kidneys with a quick fix. As a board-certified kidney doctor, I can tell you there is no magic bullet that can unclog your kidneys like an air filter. In fact, many of these products can do more harm than good.

These "cleanses" often contain proprietary or secret blends of ingredients that are not regulated. Some of these supplements can be directly toxic and harm your kidneys, worsening your kidney function instead of improving it. The idea of a "detox" can be gimmicky; your kidneys are self-cleaning organs.

Actionable Takeaway: The best way to help prevent kidney damage and support your kidneys' natural filtering ability is through proven lifestyle choices. This includes drinking plenty of water, eating antioxidant-rich foods to reduce inflammation, managing your blood sugar and blood pressure, and avoiding medications known to damage the kidneys, like NSAIDs.

7. Taking Certain Herbal Supplements Blindly

Similar to cleanses, the habit of taking herbal supplements without medical supervision can be very dangerous. Many people assume that "natural" equals "safe," but this is a critical misconception. Herbal supplements are not FDA-approved, and their ingredients can be inconsistent or unlisted.

In my clinical practice, I have seen patients develop acute kidney damage from taking certain Chinese herbs that were toxic to their kidneys. These supplements can also have dangerous interactions with prescription medications. If you don't disclose your supplement use to your doctor, you are taking a significant and unnecessary risk with your kidney health and could also be increasing your risk for heart disease.

Actionable Takeaway: Never take any herbal supplement without first consulting your physician. Always provide your doctor with a complete list of all medications and supplements you are taking to ensure there are no harmful interactions or direct risks to your kidneys.

Conclusion

We all have daily habits that seem harmless, but as I've shown, these are some of the most common habits that cause kidney failure and damage to the vital organs.  Abusing pain relievers, yo-yoing between dehydration and over-hydration, ignoring high blood pressure, and falling for the "healthy" processed food trap are all paths that can lead to kidney problems.

Protecting your kidneys doesn't require a magic "detox" or a secret supplement. It requires awareness and a commitment to the foundational health principles. By managing your blood pressure, making conscious dietary choices, staying properly hydrated, and consulting with your doctor, you can avoid these horrible habits and prevent the onset of kidney diseases.
