Have you ever:
- Noticed your shoes feel tighter than usual?
- Seen one foot or ankle puffier than the other?
- Pressed your skin and left a dent that lingers?
You’re not imagining it.
Swollen feet or ankles — medically known as edema — are more than just a sign of a long day on your feet. While they’re often harmless, sudden or persistent swelling can be a silent signal from your heart, kidneys, veins, or lymphatic system.
And ignoring it could mean missing an early warning sign of a serious condition.
Let’s explore the common causes of foot swelling, when it’s normal, and when to see a doctor — so you can respond with awareness, not fear.
🧠 What Is Edema?
Edema is the buildup of fluid in the tissues — most commonly in the feet, ankles, and legs.
It can be:
- Mild and temporary — after standing too long or during hot weather
- Chronic or sudden — a clue that your body needs attention
🔍 A simple test: Press your finger into the swollen area. If it leaves a dent (called pitting edema), it’s likely fluid retention.
