10 Common CKD Myths vs Facts

10 Common CKD Myths vs Facts

In this article we will explain 10 myths and facts about CKD.

This article is linked to another on MyHSN: Another 10 Common CKD Myths.

Myth 1: If I feel fine, my kidneys are fine.

The Fact: CKD is often called a “silent killer.” Most people do not experience noticeable symptoms (like swelling or fatigue) until they have lost over 75% of their kidney function (usually at CKD Stage 4). Regular blood and urine tests are the only way to know for sure.

Myth 2: CKD is a rare condition.

The Fact: It’s more common than you think. Globally, about 1 in 10 adults has some form of kidney disease. In the U.S. alone, an estimated 37 million people are living with CKD, and many are undiagnosed.

Myth 3: Everyone with CKD will eventually need dialysis.

The Fact: Fortunately, only 1 in 100 people with CKD progress to need dialysis or a kidney transplant.

So, a CKD diagnosis is not a destiny. With early detection, lifestyle changes, and proper medication (like ACE inhibitors or SGLT2 inhibitors), many patients can slow or even stop the progression of the disease, avoiding dialysis entirely.

Myth 4: Only “old people” get kidney disease.

The Fact: While risk increases with age, CKD can affect anyone. Factors like Type 2 diabetes, hypertension, genetics, and autoimmune disease can trigger kidney issues in children and young adults.

Myth 5: Drinking large amounts of water “flushes out” the kidneys which helps CKD.

The Fact: Whilst hydration may be useful preventing kidney stones, drinking excessive water won’t cure damaged nephrons. In fact, in advanced stages of CKD, doctors may actually restrict fluid intake because the kidneys can no longer process the volume, leading to dangerous swelling.

Myth 6: A CKD diagnosis means I can never eat salt or protein again.

The Fact: It’s about moderation and balance, not total elimination. Whilst a low sodium diet is recommended by some, your protein needs depend on your specific stage of CKD. A renal dietitian is your best resource for a personalised “kidney-friendly” plate.

Myth 7: Kidney disease is only caused by drinking too much alcohol.

The Fact: While heavy drinking can indirectly damage kidneys through liver disease and high blood pressure, the leading causes of advanced CKD (Stage 4 or 5) are Diabetes and Uncertain. These two conditions account for 50% of all new cases.

Myth 8: If I have CKD, I shouldn’t exercise.

The Fact: Physical activity is actually one of the best things you can do. Exercise helps manage blood pressure and blood sugar—two drivers of kidney damage. Just check with your doctor before starting a new, high-intensity routine.

Myth 9: Dialysis is a cure for kidney disease.

The Fact: Dialysis is a life-sustaining treatment, not a cure. It performs the filtration work the kidneys can no longer do. It provides about 5% of the function of 2 kidneys (yes, not alot). The only “cure” for end-stage renal disease (ESRD) is a successful kidney transplant, though dialysis allows patients to live long, fulfilling lives.

Myth 10: There is nothing I can do to prevent CKD.

The Fact: You have more control than you think. Managing your blood pressure, keeping your HbA1c in check, avoiding the over-use of NSAIDs (like ibuprofen), and quitting smoking are powerful ways to protect your kidneys.
