From circulation problems to heart, kidney, or vein disorders, persistent swelling in the legs should never be ignored — especially if it appears suddenly, becomes painful, or continues getting worse over time.
Why Do Legs Swell?
Leg swelling, medically known as edema, occurs when excess fluid becomes trapped in the body’s tissues. It can affect the feet, ankles, calves, or entire legs and may happen in one leg or both.
Sometimes the cause is harmless and temporary. Other times, it may point to an underlying health condition that requires medical attention.
1. Poor Blood Circulation
One of the most common causes of swollen legs is poor circulation. When blood struggles to flow properly back to the heart, fluid can collect in the lower legs and ankles.
This often happens after sitting or standing for long periods and may worsen with age.
Common signs include:
- Heavy or tired legs
- Visible veins
- Mild discomfort or tightness
- Swelling that improves after resting
2. Excess Salt Intake
Eating too much sodium can cause the body to retain water, leading to puffiness and swelling in the legs, feet, and ankles.
