Kidney disease often develops quietly. By the time symptoms appear, damage may already be underway. Here are early signs that are easy to miss—but important to catch.

7 Common Warning Signs of Kidney Disease

šŸ” 1. Constant Fatigue

If you’re feeling drained all the time, it could be more than just age or stress. Your kidneys may not be filtering waste properly.

šŸ’§ 2. Swelling in Ankles or Hands

Fluid retention is a red flag—especially if it’s new or worsening. This can be an early sign of reduced kidney function.

😰 3. Changes in Urination

Foamy, dark, or frequent urination (especially at night) could signal kidney stress.

šŸ§‚ 4. Metallic Taste or Bad Breath

Toxin buildup from poor filtration can lead to a strange taste in the mouth or persistent bad breath.

🄶 5. Feeling Cold All the Time

Anemia caused by kidney dysfunction can lead to feeling cold, even in warm environments.

šŸ’„ 6. Muscle Cramps or Twitching

Electrolyte imbalances—often linked to kidney trouble—may trigger sudden cramps or spasms.

🧠 7. Trouble Concentrating

Brain fog or confusion can happen when waste builds up in the bloodstream.
