5. Blood in the Urine
Urine that appears pink, red, or cola-colored may indicate blood.
Possible causes include:
- Kidney stones
- Urinary tract infections
- Kidney disease
- Other urinary tract conditions
6. Foamy or Bubbly Urine
Persistent foamy urine may suggest protein in the urine (proteinuria), an important sign that the kidneys' filtering system may be damaged.
7. High Blood Pressure
The kidneys help regulate blood pressure.
High blood pressure can both:
- Damage the kidneys
- Result from kidney disease
The two conditions often reinforce each other.
8. Persistent Itching
Advanced kidney disease can lead to waste products building up in the bloodstream, contributing to:
- Dry skin
- Persistent itching
- Skin irritation
9. Dry Skin
Kidneys help regulate minerals and support overall skin health.
Dry skin isn't usually caused by kidney disease alone, but when combined with other symptoms, it may warrant further investigation.
