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.
