Initial Evaluation

Your doctor will start with a physical exam and medical history. They'll look for signs of swelling and ask about your symptoms. They might check for 'pitting edema' by pressing on the swollen area to see if it leaves a dent. Your doctor will also ask about any medications you're taking, as some can cause edema.

Blood Tests

Blood tests can provide important clues about the cause of your edema. Your doctor might check your kidney and liver function, as problems with these organs can lead to fluid retention. They may also test your thyroid function and look for signs of inflammation or infection. A test called BNP can help diagnose heart failure, a common cause of edema.

Edema refers to swelling caused by excess fluid trapped in the body's tissues. It can affect any part of the body but is commonly noticed in the hands, arms, feet, ankles, and legs.

Imaging Tests

Imaging tests can help visualize what's happening inside your body. An ultrasound can check for blood clots in your legs or examine the blood flow in your veins. If heart problems are suspected, your doctor might order an echocardiogram to look at your heart's structure and function. In some cases, a CT scan or MRI might be necessary to get a more detailed view.

Specialized Tests

Depending on your symptoms, your doctor might recommend more specialized tests. If lung problems are suspected, you might need pulmonary function tests or a chest X-ray. For abdominal swelling, your doctor might perform a procedure called paracentesis to analyze fluid from your abdomen. In rare cases, a biopsy of the swollen tissue might be necessary.
