Kidney disease often develops slowly, and early signs can be easy to miss. Here are 10 common symptoms of kidney disease you should be aware of:
- Fatigue and weakness
When kidneys don’t filter waste properly, toxins build up in the blood, making you feel tired and low on energy. - Swelling (edema)
Especially in the feet, ankles, hands, or face due to fluid retention. - Changes in urination
More frequent urination, especially at night, or reduced urine output. - Foamy or bubbly urine
Can indicate excess protein in the urine. - Blood in urine
Urine may appear pink, red, or cola-colored. - Persistent itching
Waste buildup in the blood can cause skin irritation and itching. - Loss of appetite
Feeling full quickly or not feeling like eating. - Nausea or vomiting
Caused by toxin buildup in advanced stages. - Muscle cramps
Often due to electrolyte imbalances like low calcium or high phosphorus. - Difficulty concentrating or “brain fog”
Reduced kidney function can affect brain clarity and focus.
Kidney problems can be serious if ignored. If someone notices several of these symptoms—especially swelling, urine changes, or fatigue—it’s important to get medical tests like blood creatinine, eGFR, and urine analysis.
