6 warning signs your kidneys might be in trouble

Kidney dysfunction can cause sodium retention, leading to swelling in the feet, ankles, or even the face. This swelling is often painless but persistent and indicates fluid imbalance in the body.

Excessive bubbles in urine or traces of blood can suggest protein leakage or damaged kidney filters. Healthy kidneys prevent blood and protein from leaking into the urine.

An increased urge to urinate, particularly during the night, may signal impaired kidney function or infection. The kidneys may struggle to filter waste, leading to more frequent urination.

Unhealthy kidneys can't produce enough erythropoietin, a hormone that helps make red blood cells. This can result in anaemia, causing constant tiredness or weakness even after rest.

Early signs of kidney damage can include protein leakage, causing persistent puffiness around the eyes. It’s a clue that your kidneys may be allowing essential proteins to escape.

Kidney disease can reduce oxygen flow to the brain due to anaemia or toxin buildup, leading to memory issues, poor focus, or frequent dizziness and lightheadedness.
