Recognizing the Warning Signs of Kidney Failure

Recognizing the Warning Signs of Kidney Failure

Kidneys are the unsung heroes of our bodies, working tirelessly to maintain our overall health and well-being. It’s crucial, therefore, to be aware of the subtle hints they can provide when something is amiss.  Learn the signs of kidney failure that demand immediate attention.


Do you feel persistently fatigued, even after a good night’s sleep? There are many possible causes of chronic fatigue, one of them being kidney dysfunction. When our kidneys struggle to eliminate waste and excess fluids from our bodies, toxins accumulate, impacting our energy levels. If you experience unexplained exhaustion and lack of vitality over an extended period of time, your kidney health may be at risk.


Swelling due to water retention is medically referred to as edema. When your kidney function is impaired, you may notice swelling in your feet or ankles, in your hands, or around your eyes. This happens because kidneys play a vital role in regulating the body’s fluid balance. When they don’t work as they’re supposed to, excess fluid can accumulate in your tissues, resulting in noticeable swelling.

Changes in Urination

Paying attention to changes in urination patterns can provide valuable insights into your kidney health. Kidneys are responsible for filtering waste products from your blood, which are then excreted as urine. Because of this, unusual urination can indicate potential kidney problems. 

Keep an eye out for signs such as:

  • Increased frequency, 
  • Decreased volume, 
  • Pain or discomfort, 
  • The presence of blood, and 
  • Changes in urine color. 

These changes warrant further investigation and medical evaluation to determine if kidney failure may be a contributing factor.

Persistent Hypertension

Uncontrolled hypertension (high blood pressure), can significantly impact kidney function. Conversely, kidney dysfunction can also contribute to hypertension. The kidneys help regulate blood pressure by managing the balance of fluids, electrolytes, and hormones in your body. 

When your kidneys are compromised, your blood pressure can rise and remain elevated. If you have a history of hypertension, or consistently high blood pressure readings, it’s critical that you contact your healthcare provider, get your kidney function tested, and discuss interventions to protect your kidneys and overall health.
