Swollen feet and difficulty walking in an older adult can have many possible causes, and poor circulation is only one of them.
Some common causes include:
- Venous insufficiency (veins in the legs have trouble returning blood to the heart), which can cause swelling in the feet and ankles.
- Heart failure, which may lead to fluid buildup in the legs and feet.
- Kidney disease or liver disease, which can cause the body to retain fluid.
- Lymphedema, a buildup of lymph fluid that causes swelling.
- Certain medications, such as some blood pressure medicines, steroids, or anti-inflammatory drugs.
- Blood clots, infections, injuries, or inflammatory conditions.
