Our kidneys play a vital role in keeping our bodies healthy. Located just below the rib cage, these organs filter blood, remove waste and excess fluids, regulate electrolyte levels, and produce hormones that help maintain healthy bones, red blood cells, and blood pressure. Recognizing the early signs of kidney issues is crucial for preventing more serious complications.

Here are some scientifically supported signs that may indicate kidney problems:

1. Swelling

When the kidneys struggle to remove excess fluids, swelling can occur in areas like the face, hands, feet, or legs. Persistent or unexplained swelling may signal kidney dysfunction and should prompt a visit to a healthcare provider.

2. Changes in Urination

Changes in the frequency, color, or appearance of urine can be early indicators of kidney issues. For example:

Reduced urination or difficulty passing urine.
Dark or foamy urine, which may suggest the presence of protein.
Increased urination at night (nocturia).
While these signs can also be linked to other conditions, they warrant further investigation if persistent.
