Swollen feet, or edema, happen when fluid builds up in the tissues. It’s common and can feel uncomfortable, especially if it appears suddenly or doesn’t go away.

You may notice your feet looking larger, feeling tight in shoes, or having stretched, shiny skin. Pressing the area might leave a dent, called “pitting edema.” For many, it develops slowly after a long day.

There are several everyday causes. Sitting or standing too long can affect circulation, and heat can expand blood vessels, leading to swelling. Diet also matters—too much salt makes the body retain fluid. Pregnancy is another common cause due to hormonal and circulation changes. However, swelling can sometimes be linked to issues with the heart, kidneys, liver, or certain medications.

While mild swelling is often harmless, warning signs should not be ignored. Seek medical care if it “appears suddenly without a clear reason,” affects only one foot, or comes with pain, redness, warmth, shortness of breath, or chest discomfort.

For mild cases, some natural remedies may help. Herbs like ginkgo biloba and horse chestnut support circulation, while dandelion acts as a natural diuretic. Soothing options like chamomile or calendula foot soaks can reduce discomfort. Still, these are only supportive.

A balanced approach works best. Elevating your feet, staying active, reducing salt, and wearing comfortable shoes can ease symptoms. If swelling is persistent or severe, it’s important to seek medical advice to find the underlying cause.
