If you follow our Health Hub fan page, you may have seen that we explore the hidden “red flags” that pique people’s curiosity. This guide presents 23 often-overlooked symptoms of kidney problems, based on reliable sources like the Mayo Clinic and Kidney.org, along with real-life examples and practical advice.

Urinary Changes You Shouldn’t Ignore
1. Foamy or Sparkling Urine

Persistent bubbles after flushing can mean that protein is leaching into your urine, a sign that your kidney filters are under stress.

💡 Tip: Keep a hydration diary to distinguish dehydration from kidney problems.

2. Frequent Nighttime Urination (Nocturia)
The need to urinate more than once or twice during the night can indicate that your kidneys are having trouble concentrating urine.

💡 Tip: Limit evening fluids and monitor the frequency for a week.

3. Blood in the Urine (Hematuria)
Pink, red, or cola-colored urine can indicate inflammation, kidney stones, or an infection. 💡 Tip: Use home test strips for quick monitoring, but consult a doctor promptly.

4. Decreased urine output.
Producing significantly less urine despite normal hydration may indicate reduced kidney function.

💡 Tip: Use apps to track urine intake/output to identify trends.

Skin and appearance changes
5. Dry, itchy skin.
This can be due to a buildup of toxins or a mineral imbalance in later stages of CKD.

💡 Tip: Moisturizing creams can help, but a blood test is essential.

6. Swelling of the feet, ankles, or hands
