# Swelling

[Resources](https://www.australiawidefirstaid.com/resources) › [Glossary](https://www.australiawidefirstaid.com/resources/glossary)

## What is Swelling?

Swelling is an increase in the size of a body part due to fluid accumulation, often as a result of injury or inflammation.

Swelling, also known as edema, refers to the abnormal accumulation of fluid in tissues, leading to noticeable enlargement or puffiness. Swelling can result from injury, inflammation, infection, or medical conditions affecting circulation or lymphatic drainage.

In first aid, assessing and managing swelling helps alleviate discomfort and prevent complications such as impaired circulation or tissue damage.

Initial treatment includes rest, elevation of the affected limb above heart level, and applying ice packs wrapped in a cloth to reduce inflammation and pain. Compression with an elastic bandage helps support the affected area and minimise fluid accumulation. Monitoring the casualty for signs of worsening swelling, such as increased pain or skin discoloration, guides ongoing care and may indicate the need for medical evaluation.

## First Aid for Swelling

1. Rest: Avoid using the swollen area.
2. Ice: Apply ice packs to reduce swelling and pain.
3. Compression: Use an elastic bandage to support the area and limit swelling.
4. Elevation: Keep the swollen area elevated above heart level.
