Kidneys regulate blood pressure by balancing fluids and releasing renin. When damaged, they can cause or worsen hypertension. A 2019 Hypertension study linked uncontrolled blood pressure to kidney damage in 22% of cases.
What to Do: Monitor blood pressure daily, reduce salt, and consult a doctor for medication adjustments.
7. Metallic Taste or Ammonia Breath
Waste buildup in the blood (uremia) can cause a metallic taste or ammonia-like breath. A 2021 Journal of Renal Nutrition study noted this in 15% of kidney disease patients, often with appetite loss.
What to Do: Stay hydrated, chew sugar-free gum, and see a doctor for kidney function tests.
8. Back or Side Pain
Kidney infections, stones, or cysts can cause pain in the lower back or sides. A 2022 Urology study found kidney-related pain in 20% of patients with undiagnosed kidney issues.
What to Do: Note pain patterns and seek a doctor for imaging or urinalysis.
9. Poor Appetite or Nausea
Toxin buildup can suppress appetite or cause nausea, often early in kidney dysfunction. A 2020 Nephrology Dialysis Transplantation study linked these symptoms to 12% of early-stage cases.
What to Do: Eat small, bland meals and consult a doctor if symptoms persist.
10. Trouble Sleeping
Kidney issues can disrupt sleep due to restless legs, itching, or fluid buildup. A 2021 Sleep Medicine study found sleep disturbances in 30% of kidney disease patients.
What to Do: Maintain a sleep routine, limit caffeine, and see a doctor for underlying causes.

Real-Life Stories: Catching Kidney Issues Early
Lisa, a 55-year-old teacher, noticed persistent fatigue and swollen ankles. After blood tests revealed early kidney dysfunction, she cut salt, added berries to her diet, and worked with a nephrologist. Within months, her symptoms improved, avoiding further damage.
Tom, a 60-year-old retiree, experienced foamy urine and itching. A urine test detected proteinuria, leading to early treatment for kidney disease. These cases show how recognizing signs and acting quickly can protect kidney health.
