Swollen feet are a common concern among older adults. While mild swelling can occur after long periods of sitting or standing, frequent or persistent swelling may signal an underlying issue. Understanding the causes and simple prevention methods can help maintain comfort, mobility, and overall well-being. This condition, known as edema, happens when excess fluid builds up in the tissues of the lower legs and feet.

As people age, circulation can become less efficient, making fluid retention more likely. Slower blood flow allows fluid to collect in the ankles and feet, leading to visible swelling and discomfort. Poor circulation is one of the most common causes, especially for those who sit or stand for extended periods. Chronic venous insufficiency, where leg veins struggle to return blood to the heart, can also contribute to swelling.

Additionally, some medications—such as those used for blood pressure or inflammation—may cause fluid retention. In certain cases, swelling may be linked to more serious conditions affecting the heart, kidneys, or liver. Lifestyle factors play an important role as well. Limited physical activity, long periods of inactivity, and high salt intake can all increase swelling. Fortunately, there are practical ways to reduce or prevent it.

Staying active, taking regular breaks to move around, elevating the feet, and wearing comfortable, supportive shoes can improve circulation. Compression socks may also help. A balanced diet with reduced sodium and adequate hydration supports healthy fluid balance. By making these small adjustments, older adults can better manage swelling and maintain healthier, more comfortable feet.
