Have you ever noticed your feet, ankles, or legs looking unusually swollen after a long day? While occasional swelling can be harmless, persistent or sudden swelling—known medically as edema—may sometimes signal an underlying health issue.
Edema is not a disease itself. Rather, it’s a symptom caused by excess fluid collecting in the body’s tissues. Understanding what causes it can help you know when simple home care is enough and when it’s time to seek medical advice.
What Is Edema?
Edema occurs when fluid leaks from tiny blood vessels and becomes trapped in nearby tissues. This extra fluid causes the affected area to appear swollen or puffy.
Edema most commonly affects:
- Feet
- Ankles
- Lower legs
- Hands
- Arms
In some cases, it may also affect the face or abdomen.
Common Symptoms
Depending on the cause, edema may include:
- Swollen feet or ankles
- Puffiness under the skin
- Tight or shiny skin
- Shoes or rings feeling tighter than usual
- Reduced flexibility in the affected joints
- A feeling of heaviness in the legs
Sometimes, pressing gently on the swollen area leaves a temporary indentation. This is known as pitting edema.
Common Causes of Edema
Many different conditions can lead to swelling. Some are temporary and harmless, while others require medical treatment.
