Causes of Lower Extremity Edema

Once you know it’s edema, causes need to be determined. Why is the fluid building up in your tissues?

Side Effects of Medication

Some prescription drugs for blood pressure, inflammation, and pain management list edema as a side effect.


When you sit or stand in one place for too long, gravity pulls water down into your lower extremities.

Underlying Medical Conditions

Edema can be a symptom of conditions like lung, liver, thyroid, and kidney disease and congestive heart failure.


Some pregnant women get edema as the uterus puts pressure on the blood vessels causing swelling in the legs.

Weak Immune System

Infections, burns, allergic reactions, clots, and trauma can lead to edema.

Venus Insufficiency

If your veins have weak valves, it makes it difficult for the veins to push blood back to your heart. This condition leads to varicose veins and a buildup of fluid.


Foods high in sodium and a poor diet can lead to fluid build-up in the body.


Treatment depends on the cause. If it’s a side effect of medication, your doctor will adjust the dosage. Your doctor may also recommend wearing compression socks.

Other treatments include elevating your legs or arms, exercising, and cutting the amount of salt in your diet. If you sit or stand a lot, move around from time to time. You can also massage the swollen area pushing the fluid toward the heart.

Is it Time to See a Doctor?

Now you know the causes of lower extremity edema. They can range from something simple to something more serious. It’s best to see a doctor to determine what’s causing it. Your primary care physician can help you get the proper treatment. If left untreated, you may end up dealing with other complications.
