Swollen Feet in Older Adults: Common Causes and Prevention

Several everyday habits may increase the risk of swollen feet. Lack of physical activity can slow circulation and make fluid buildup more likely. Similarly, sitting for extended periods—such as during long car rides or flights—can contribute to swelling.

A diet high in salt can also lead to water retention. Sodium causes the body to hold onto fluid, which can worsen swelling in the feet and ankles.

Being overweight may place extra pressure on the veins in the legs, making it harder for blood to circulate effectively.

Prevention and Simple Solutions

Fortunately, there are many ways older adults can reduce or prevent swelling in the feet.

One of the simplest strategies is regular movement. Walking, gentle stretching, or light exercise helps improve circulation and encourages fluid to move through the body. Even short walks several times a day can make a difference.

Another helpful habit is elevating the feet. Raising the feet above heart level for 15–30 minutes can help reduce swelling by allowing fluid to drain away from the lower legs.

Wearing comfortable, supportive footwear is also important. Shoes that fit well and provide proper support can help reduce pressure on the feet and improve circulation.

Many older adults benefit from compression socks, which gently support the legs and help blood flow back toward the heart. These socks can be especially helpful for individuals who sit or stand for long periods.

Diet also plays a key role. Reducing sodium intake and eating foods rich in potassium, such as bananas, leafy greens, and avocados, can help maintain healthy fluid balance.
