1. Persistent Fatigue and Weakness
Feeling unusually tired and weak, even after adequate rest, is a common but often overlooked sign of elevated creatinine levels. As kidney function declines, waste products accumulate in the bloodstream, forcing your body to work harder to maintain normal functions. This buildup can lead to persistent fatigue, leaving you drained despite minimal physical activity.
This fatigue differs from typical tiredness because it doesn’t improve significantly with rest. If you find yourself struggling with energy throughout the day or noticing weakness in your muscles, it’s worth discussing kidney function with your healthcare provider. They can evaluate creatinine levels and other markers to determine if kidney health is a factor.
2. Swelling in the Legs, Ankles, or Feet
Edema, or swelling caused by fluid retention, can be an early indicator of impaired kidney function. When kidneys cannot efficiently remove excess fluid and sodium, it accumulates in tissues, particularly in the lower extremities where gravity causes fluid to pool.
You might notice tighter shoes or socks leaving indentations on your skin. This swelling may not disappear after rest and can gradually worsen. Persistent edema should prompt evaluation by a healthcare professional, as it can signal kidney problems or other conditions such as heart failure or liver disease.
