What is the relationship between swelling and edema?

Swelling and edema are two terms that are often used interchangeably, but they actually have slightly different meanings.

* Swelling is a general term that refers to an increase in the size of a body part. This can be caused by a variety of factors, including inflammation, infection, injury, or fluid retention.

* Edema is a specific type of swelling that is caused by an accumulation of fluid in the tissues. This can occur for a variety of reasons, including heart failure, kidney disease, liver disease, or pregnancy.

In most cases, swelling and edema are not serious problems and will resolve on their own. However, if you experience sudden or severe swelling, it is important to see a doctor to rule out any underlying medical conditions.

Here are some of the symptoms of swelling and edema:

* Swelling in the hands, feet, ankles, or legs

* Puffiness in the face

* Difficulty fitting into shoes or clothes

* Pain or tenderness in the affected area

* Warmth or redness in the affected area

If you experience any of these symptoms, it is important to see a doctor to determine the cause.
