Reduced physical activity also plays a role. Movement helps circulate blood and lymph fluid, while inactivity allows fluid to collect in the lower limbs. Even light daily exercise such as walking or gentle leg movements can noticeably improve circulation and reduce swelling.
In some cases, swelling may signal more serious conditions like deep vein thrombosis (DVT), especially if it appears suddenly or affects only one leg and requires urgent attention. Common management includes elevating the legs, using compression stockings, staying active, and reducing salt intake, but persistent or painful swelling should always be evaluated by a healthcare professional.
