If Your Kidneys Aren’t Working Properly, the Body May Show These 10 Signs
Your kidneys help remove waste from the blood, balance fluids, regulate blood pressure, and support healthy red blood cell production. When kidney function declines, symptoms may appear gradually and can be easy to overlook.
Here are 10 possible warning signs of kidney problems:
1. Changes in Urination
- Needing to urinate more often, especially at night
- Urinating much less than usual
- Foamy or bubbly urine
- Blood in the urine
- Changes in urine color
2. Swelling in the Legs, Ankles, Feet, or Around the Eyes
When kidneys struggle to remove extra fluid and sodium, fluid can build up in tissues, causing swelling.
3. Unusual Tiredness or Low Energy
Reduced kidney function can contribute to a buildup of waste products in the blood and may also lead to anemia, which can cause fatigue.
4. Trouble Sleeping
Kidney problems may be associated with sleep difficulties, itching, muscle discomfort, or the need to urinate frequently at night.
5. Dry, Itchy Skin
A buildup of minerals and waste products can sometimes cause persistent itching and changes in skin condition.
6. Loss of Appetite or Nausea
Waste buildup in the body may affect digestion and appetite, sometimes causing nausea, vomiting, or an unpleasant taste in the mouth.
7. Muscle Cramps or Weakness
Imbalances in minerals such as calcium, potassium, or phosphorus can contribute to muscle symptoms.
8. Shortness of Breath
Fluid buildup or anemia related to kidney disease may make breathing feel more difficult.
9. Difficulty Concentrating or Feeling Confused
Changes in body chemistry caused by reduced kidney function may affect mental clarity and concentration.
10. High Blood Pressure That Is Difficult to Control
Kidneys play a major role in blood pressure regulation. Kidney disease and high blood pressure can worsen each other.
When to Seek Medical Advice
Contact a healthcare professional if you notice persistent changes in urination, swelling, unexplained fatigue, blood in urine, or other concerning symptoms—especially if you have risk factors such as:
- Diabetes
