Medications can also contribute. Drugs used for blood pressure, pain relief, or inflammation may have side effects that include swelling. Because many older adults take multiple prescriptions, these effects can sometimes be overlooked or mistaken for aging itself.

Reduced physical activity is another key contributor. Movement helps circulate blood and lymph fluid, and inactivity allows fluid to accumulate in the lower limbs. Even light daily activity like walking or gentle leg exercises can make a noticeable difference.

In some cases, swelling may point to more serious conditions such as deep vein thrombosis (DVT), especially if it appears suddenly or affects only one leg. This requires prompt medical attention due to the risk of complications.

Management often includes elevating the legs, using compression stockings, staying active, and reducing salt intake. However, because swelling can have multiple causes, persistent or painful symptoms should always be evaluated by a healthcare professional.
