23 Possible Warning Signs of Kidney Disease You Should Never Ignore
Your kidneys work around the clock to keep your body healthy. These two bean-shaped organs filter about 50 gallons (190 liters) of blood every day, removing waste products, balancing fluids, regulating blood pressure, producing hormones, and maintaining healthy levels of minerals such as sodium and potassium.
The problem is that kidney disease often develops silently. Many people have no noticeable symptoms until significant kidney function has already been lost. That's why understanding the early warning signs is so important.
The image above highlights several symptoms that are often associated with kidney problems. While none of these signs alone can diagnose kidney disease, persistent or multiple symptoms should prompt a medical evaluation.
Here are 23 possible warning signs that may indicate your kidneys need attention.
1. Persistent Fatigue
Healthy kidneys produce erythropoietin, a hormone that helps make red blood cells. When kidney function declines, anemia can develop, leading to:
- Constant tiredness
- Low energy
- Weakness
- Difficulty concentrating
2. Swelling of the Feet and Ankles
Damaged kidneys may struggle to remove excess salt and fluid, causing swelling in the:
- Feet
- Ankles
- Lower legs
- Sometimes the hands
This symptom is called edema.
3. Puffiness Around the Eyes
Protein leaking into the urine may reduce the body's ability to keep fluid inside blood vessels, leading to swelling around the eyes, especially in the morning.
4. Changes in Urination
Pay attention if you notice:
- Urinating more often
- Urinating less than usual
- Waking frequently at night to urinate
- Difficulty urinating
- Weak urine stream
These changes can have many causes but deserve medical evaluation if persistent.
