If You Notice Your Legs Are Swollen, Doctors Warn It Could Be a Sign of a Serious Underlying Condition

Swollen legs in older adults are often linked to aging changes, but they can also signal health problems. Common causes include poor circulation, reduced activity, and fluid retention from heart, kidney, or liver issues.

Certain medications and high salt intake can also worsen swelling. In some cases, sudden or one-sided swelling may indicate a serious condition like a blood clot and needs urgent medical attention.

Simple steps like staying active, elevating the legs, and reducing salt may help—but persistent swelling should always be checked by a doctor.
