If you’re referring to the headline “23 Strange Signs Your Kidneys Might Be in Trouble,” here are some possible warning signs of kidney problems. Many of these symptoms can have other causes, so they do not confirm kidney disease on their own.
Possible signs that may be linked to kidney issues:
- Changes in urination (more or less frequent than usual)
- Waking up often at night to urinate
- Foamy or unusually bubbly urine (possible protein in urine)
- Blood in the urine
- Dark, cloudy, or unusual-smelling urine
- Swelling in the feet, ankles, hands, or around the eyes
- Persistent fatigue or low energy
- Trouble concentrating or feeling mentally foggy
- Loss of appetite
- Nausea or vomiting
- Unexplained weight loss
- Itchy skin
- Dry skin
- Muscle cramps
- Shortness of breath (from fluid buildup or anemia)
- High blood pressure that is difficult to control
- Back or side pain near the kidney area (especially with certain kidney conditions)
- Feeling cold more often than usual
- Metallic taste in the mouth or changes in taste
- Bad breath with a urine-like odor
- Persistent puffiness around the eyes
- Difficulty sleeping
- Frequent infections or reduced immunity in some cases
Kidney disease can develop quietly, especially in its early stages. People with diabetes, high blood pressure, a family history of kidney disease, or long-term use of certain medications may benefit from regular kidney checks.
Doctors typically evaluate kidney health with tests such as blood creatinine/eGFR tests and urine tests for protein or albumin—symptoms alone are not enough to diagnose a kidney problem. If there is blood in urine, severe swelling, chest pain, severe shortness of breath, or a sudden major change in urination, medical advice should be sought promptly.
