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.
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.
