Swollen feet might seem like a minor inconvenienceāsomething caused by a long day of standing or hot weather. But in some cases, it can also be an early warning sign that your body is dealing with an underlying issue that shouldnāt be ignored.
Letās break down what swollen feet can actually mean, when itās harmless, and when it could signal something more serious.
𦶠What Is Foot Swelling (Edema)?
Foot swelling, medically known as edema, happens when fluid builds up in the tissues of your feet, ankles, or lower legs.
It may appear as:

- Difficulty fitting into shoes
- A heavy or uncomfortable feeling
Sometimes itās temporaryābut other times, it may be linked to health conditions that need attention.
ā ļø Common (and Usually Harmless) Causes
