What are the signs of worsening kidney function if creatinine levels are elevated?

Signs of worsening kidney function can include fatigue, swelling (especially in the legs, ankles, and feet), shortness of breath, nausea, and changes in urine output. Elevated creatinine levels may also be accompanied by symptoms like high blood pressure and difficulty concentrating. If you experience any of these symptoms, it’s important to contact your healthcare provider for further evaluation. Early detection and treatment of declining kidney function can help prevent serious complications, including kidney failure.
