Why could my feet and legs be so swollen I am not old or not over weight?

Swollen feet and legs can result from various factors, even in younger or healthier individuals. Common causes include prolonged sitting or standing, which can lead to fluid retention, or conditions like venous insufficiency. Other potential factors might include dietary salt intake, hormonal changes, or even minor injuries. If the swelling persists or is accompanied by pain or other symptoms, it's important to consult a healthcare professional for a proper evaluation.
