Topic pages summarize public health information in plain language. They may describe common causes and treatments in general terms; your own plan of care depends on your clinician’s exam, history, and tests.

Edema means swelling caused by fluid in your body's tissues. It usually occurs in the feet, ankles and legs, but it can involve your entire body.
Causes of edema include:
- Eating too much salt
- Sunburn
- Heart failure
- Kidney disease
- Liver problems from cirrhosis
- Pregnancy
- Problems with lymph nodes, especially after mastectomy
- Some medicines
- Standing or walking a lot when the weather is warm
To keep swelling down, your health care provider may recommend keeping your legs raised when sitting, wearing support stockings, limiting how much salt you eat, or taking a medicine called a diuretic - also called a water pill.
