BY: ET Online8 early signs your kidney might be in trouble
Changes in urination patterns
Frequent urination at night, foamy urine, or decreased urine output may be early signs of kidney trouble. These changes often indicate impaired filtration or protein leakage.

Swelling in feet, ankles, or face
Fluid retention in the body, especially around the ankles, legs, and under the eyes, can signal reduced kidney function and salt imbalance, leading to visible puffiness.

Persistent fatigue and weakness
Damaged kidneys produce less erythropoietin, a hormone that helps make red blood cells. This can lead to anemia, causing constant tiredness, low energy, and shortness of breath.

Nausea, vomiting, or metallic taste
Accumulation of waste in the blood due to kidney dysfunction can cause nausea, poor appetite, and a persistent metallic taste in the mouth, signs often overlooked in early stages.

Healthy kidneys regulate minerals and fluid levels. When they start failing, dry, itchy, or flaky skin can emerge as a symptom of poor filtration and mineral imbalance.

High blood pressure that’s hard to control
The kidneys and blood pressure are directly connected. When the kidneys fail, they can’t regulate blood pressure effectively, leading to persistent hypertension that’s tough to manage.

Blood in urine
Blood in urine (hematuria) may indicate kidney stones, infection, or serious damage. It should never be ignored, even if it appears just once, as it can point to advanced issues.
