Swollen Legs and Ankles? Here’s What Your Body May Be Trying to Tell You

Swollen feet and ankles are often dismissed as a minor inconvenience, but they can sometimes signal underlying health issues that should not be ignored.

Swelling in the legs, ankles, and feet is a common problem that affects millions of people. While occasional swelling after a long day of standing or sitting is usually harmless, persistent or severe swelling may indicate an underlying medical condition.

Medical experts refer to this buildup of fluid in the body's tissues as edema. Understanding what causes edema can help people recognize when it is time to seek medical attention.

Poor Circulation

One of the most common causes of swollen legs is poor circulation. As people age, blood vessels and veins can lose some of their elasticity, making it more difficult for blood to return efficiently from the legs back to the heart.

When circulation slows, gravity causes fluid to accumulate in the lower extremities. This often leads to swelling around the feet and ankles, especially after long periods of sitting, standing, or inactivity.

People with chronic venous insufficiency may notice swelling that worsens throughout the day and improves after elevating their legs.

Fluid Retention (Edema)

Edema occurs when excess fluid becomes trapped in body tissues. This condition can be linked to several health issues, including heart disease, kidney disorders, liver disease, and hormonal imbalances.
