Swollen feet in older adults are often the visible surface of a deeper problem: the body’s struggle to move blood and fluid efficiently. As circulation slows with age, gravity pulls fluid into the lower legs, especially during long periods of sitting or standing. Veins that no longer return blood effectively, medications that cause fluid retention, and hidden heart, kidney, or liver issues can all turn mild puffiness into chronic edema.

The good news is that small, consistent changes can make a powerful difference. Gentle, regular movement—short walks, ankle circles, and avoiding long stretches without standing—helps pump blood back toward the heart. Elevating the feet, choosing supportive footwear, and wearing compression socks can ease pressure and reduce swelling. Cutting back on salt while eating more potassium-rich foods supports healthier fluid balance. By paying attention to swelling early and responding with lifestyle adjustments and medical guidance, older adults can protect their comfort, mobility, and long-term health.
