Because the kidneys create urine, any significant changes can signal an issue. Common changes include:
- Urinating more or less often than usual
- Dark, cloudy, or foamy urine
- A strong odor
- Discomfort while urinating
- Feeling pressure even after going to the bathroom
These changes can also be caused by dehydration, infection, or other conditions, but it’s still important to pay attention to them.
4. Lower Back or Side Pain
Kidney-related discomfort is usually felt in the lower back, on either side of the spine, just below the rib cage. The pain can be:
- Sharp
- Dull
- Constant
- Occasional
It may affect one or both sides. This type of pain is different from muscle pain because it doesn’t always improve with movement or massage.
5. Difficulty Concentrating or Brain Fog
When waste builds up in the blood due to decreased kidney function, it can affect mental clarity. People may experience:
- Trouble focusing
- Forgetfulness
- Difficulty staying alert
- Feeling mentally “slower” than usual
This happens because the brain relies on clean, well-balanced blood to function properly.
