Heart failure can reduce the heart’s ability to pump blood efficiently, causing fluid to collect in the legs and feet. Kidney disease may prevent the body from removing extra fluid properly. Liver disease can also affect fluid balance and circulation.

A blood clot, especially if swelling happens suddenly in only one leg, can become dangerous and requires immediate medical attention. Signs such as redness, warmth, pain, or shortness of breath should never be ignored.

Varicose veins are another common cause. Damaged veins struggle to move blood back toward the heart, leading to swelling, aching, and heaviness in the legs.

Simple Ways to Reduce Leg Swelling

 

In many cases, lifestyle changes may help improve mild swelling.

Try elevating your legs for 15 to 30 minutes in the evening. Raising your legs above heart level can help fluid move back through the circulation system.

Regular walking and light exercise improve blood flow and reduce fluid buildup. Avoid sitting or standing in one position for too long.
