10 Warning Signs Your Kidneys May Be Struggling — Symptoms You Should Never Ignore

When kidneys cannot efficiently remove excess fluid, swelling may develop in different parts of the body. The ankles and feet are especially common locations.

This swelling often appears gradually and may worsen throughout the day.

3. Changes in Urination

Your urine can provide important clues about kidney health. Warning signs include:

• Urinating more frequently, especially at night
• Producing less urine than usual
• Foamy or bubbly urine
• Dark-colored urine
• Blood in the urine

Any significant change should be discussed with a healthcare professional.

4. Persistent Itching

Kidney problems can cause waste products to accumulate in the bloodstream. This buildup may lead to dry, itchy skin that does not improve with moisturizers.

Severe itching can sometimes be one of the earliest overlooked symptoms of kidney dysfunction.

5. Lower Back Pain

Pain near the kidneys, located on either side of the lower back, can sometimes signal kidney stones, infections, or other kidney-related conditions.

While not all back pain is related to the kidneys, pain accompanied by urinary symptoms should be evaluated promptly.
