Creatinine is a waste product produced by muscles and normally filtered out by the kidneys. When kidney function begins to decline, creatinine levels can rise in the blood.

High creatinine does not usually cause obvious symptoms at first—but the body can give subtle early warning signs that something may not be working properly.

Understanding these signals early can help you seek medical advice sooner and protect long-term kidney health.

🧠 What does high creatinine mean?

Elevated creatinine levels may indicate:

• Or underlying kidney disease in some cases
