Kidney health is often surrounded by misinformation, making it hard to separate fact from fiction. These myths can lead to misunderstandings about how the kidneys function and what’s needed to keep them healthy. Below are ten common kidney health myths and the truths behind them.

Myth 1: Normal urination means your kidneys are fine.
This is false. While normal urination is a positive sign, it does not guarantee that your kidneys are functioning properly. Many people with kidney disease, including those who eventually need dialysis or a transplant, continue to produce normal amounts of urine. Kidney health is better assessed through blood and urine tests, not just by observing urination patterns.
Myth 2: Getting up at night to urinate is due to kidney problems.
While this can be true in some cases, it’s not the most common reason. Nighttime urination, or nocturia, is often caused by factors such as drinking liquids before bed, medications, diabetes, bladder issues, or an enlarged prostate. Aging also plays a significant role—around 50% of adults aged 50–79 experience nocturia.
Myth 3: Alcohol causes kidney disease.
This is mostly false. While excessive alcohol use can harm your body, it’s more commonly associated with liver damage than kidney disease. However, heavy drinking can lead to conditions like high blood pressure or liver disease, which may indirectly impact kidney health. Moderation is key for overall health.
Myth 4: Coffee is bad for your kidneys.
Good news for coffee lovers—this is false. Moderate coffee consumption is generally safe and may even offer some kidney protection. Studies suggest a potential link between coffee intake and a reduced risk of chronic kidney disease (CKD). For the best results, drink your coffee black.
Myth 5: Kidney disease is uncommon.
This is a myth. Kidney disease is more prevalent than many realize. According to the CDC, approximately 15% of U.S. adults—about 37 million people—have CKD, and many are unaware of it. Early detection is crucial to managing the condition and slowing its progression.
Myth 6: Cleanses help keep kidneys healthy.
False. The kidneys are designed to detoxify the body naturally and don’t need external “cleanses” to do their job. There is no scientific evidence supporting the use of detox drinks or cleanses to improve kidney health. Instead of wasting money on these products, focus on maintaining a healthy lifestyle.
Myth 7: Kidney disease causes pain.
For most people, this is untrue. Kidney disease usually does not cause pain. Pain in the kidney area is typically related to infections, cysts, or kidney stones rather than chronic kidney disease.
Myth 8: You need two kidneys to be healthy.
This is false. While having two kidneys is ideal, a person can live a healthy life with just one. In cases of kidney donation or surgical removal, the remaining kidney often adapts by growing larger and compensating for the lost function.
Myth 9: You’ll know if you have kidney disease.
This is a dangerous myth. Kidney disease is often silent in its early stages and may not show symptoms until it’s advanced. Regular screenings and blood tests are essential, especially for those with risk factors such as diabetes, high blood pressure, or a family history of kidney disease.
Myth 10: There’s no treatment for chronic kidney disease (CKD).
This is entirely false. While CKD cannot be cured, there are many ways to manage the condition and slow its progression. Lifestyle changes, medications, and working closely with a kidney specialist can make a significant difference.
Kidney health is vital, and understanding these common myths can help dispel confusion. Share this information to spread awareness and encourage regular health checkups for early detection of kidney issues.
