Swollen feet might seem minor, but they can signal serious health problems. “Conditions such as poor circulation, fluid retention, or inflammation often contribute” to swelling in the lower legs.

Occasional swelling after standing or a long day may be normal. However, “persistent or severe swelling should not be ignored.” Signs like redness, warmth, or pain could point to infection, blood clots, or heart issues.

One major cause is poor circulation. With **chronic venous insufficiency**, veins struggle to return blood to the heart, causing fluid buildup. This is especially common in older adults and appears more by day’s end.

Kidney or liver problems can also lead to fluid retention and swelling. “Hormonal changes, certain medications, or excessive salt intake may worsen the problem.”

Injuries — like sprains or fractures — and inflammatory diseases such as arthritis or gout can trigger swelling and pain.

If swelling appears suddenly, affects one leg, or is paired with chest pain or shortness of breath, “seek medical help immediately.”

Your feet can offer important clues about your health. Watch for changes — they might help detect serious conditions early.
