Edema itself is not hard to diagnose. Your child’s physician will ask about her medical history, as well as about her eating and drinking habits to see how much sodium (which causes the body to retain water) she consumes.
The physician will also look at the swollen area(s), and check to see if the skin appears stretched and shiny. Pushing gently on the swollen area for about 15 seconds will often leave a dimple.
The doctor may want to order some lab tests to see what is causing the edema. These might include:
- urine test
- blood tests
An imaging test, such as a chest x-ray, may also provide information about what is causing the swelling.
