3. Changes in Urination
Alterations in urination patterns can signal kidney distress. These changes include:
- Increased frequency, especially nocturia (waking up at night to urinate)
- Foamy or bubbly urine, which may indicate protein leakage (proteinuria)
- Dark or unusually colored urine
- Presence of blood in the urine (hematuria)
Proteinuria is a key marker of kidney damage and often precedes more obvious symptoms. If you notice any of these changes, it is essential to have a urine analysis to assess kidney health.
4. Puffiness Around the Eyes
Swelling around the eyes, especially noticeable in the morning, can indicate that protein is leaking into the urine—a hallmark of kidney dysfunction. This periorbital edema occurs because proteins that normally remain in the bloodstream pass into the urine, reducing oncotic pressure and causing fluid to leak into surrounding tissues.
While puffiness can result from allergies or lack of sleep, persistent or worsening puffiness warrants medical attention for possible kidney involvement.
5. Dry, Itchy Skin
Kidney impairment can cause mineral and toxin accumulation that affects skin health. This often manifests as dryness, persistent itching, or irritation that does not respond to topical moisturizers.
The underlying cause is the inability of damaged kidneys to maintain proper electrolyte and waste balance, leading to disturbances in skin hydration and nerve function. Chronic kidney disease patients often report this symptom as a significant quality-of-life issue.
