Swollen feet may seem harmless, but they can signal what’s happening inside your body.
Most cases are due to edema—fluid leaking from blood vessels and collecting in tissues, often in the feet because of gravity. This commonly happens after long periods of sitting, standing, heat exposure, or high salt intake.
Lifestyle factors play a big role. Too much sodium, lack of movement, and hot weather can all cause fluid retention. Injuries can also lead to temporary swelling as part of the body’s healing process.
However, persistent or unusual swelling can point to deeper issues. Problems with the heart, kidneys, or liver may disrupt fluid balance, causing buildup in the lower limbs.
Watch for warning signs:
- One foot swelling more than the other
- Skin that stays indented when pressed
- Redness, warmth, or pain
- Swelling with shortness of breath or chest pain
These may require urgent medical attention.
For most people, simple habits help:
- Elevate your feet
- Move regularly
- Reduce salt intake
- Stay hydrated
- Consider compression socks
In short, swollen feet are your body’s way of communicating. Sometimes it’s harmless—but sometimes it’s a signal worth paying attention to.
