Swollen feet might seem like a minor inconvenience, but they can actually reveal important clues about your overall health. When your feet or ankles retain fluid or appear puffy, it may be a sign that something deeper is going on in your body.

One common cause is poor circulation, especially in individuals who sit or stand for long periods. When blood doesn’t flow properly, fluid can collect in the lower limbs, leading to swelling and discomfort.

Fluid retention, also known as edema, can occur for several reasons, including high salt intake, hormonal changes, or medication side effects. In many cases, making simple lifestyle adjustments—like elevating your legs or reducing sodium—can help reduce swelling.

However, persistent swelling may signal a more serious condition, such as heart, kidney, or liver disease. These organs help regulate fluid balance, and when they’re not functioning properly, the body can retain excess fluid in the feet and ankles.

Swelling accompanied by pain, redness, or warmth might indicate an infection or inflammation due to arthritis or injury. These symptoms shouldn’t be ignored and should be evaluated promptly by a healthcare professional.

Blood clots can also cause swelling in one foot or leg, often with tenderness or a heavy feeling. This is a medical emergency and requires immediate attention to prevent complications like pulmonary embolism.

Sometimes, swelling may simply result from heat, pregnancy, or prolonged standing, which can temporarily affect circulation. Gentle exercise, hydration, and compression socks often help in these cases.

While not all swelling is serious, it’s important to pay attention to your body’s signals. If your feet remain swollen for several days or the condition worsens, consult a doctor. Early intervention can prevent larger health problems and help keep you on your feet—literally.
