Swelling of the legs and feet, also known as edema, occurs when excess fluid gets trapped in the tissues of the lower extremities. Health problems, such as liver, kidney or heart disease, may lead to generalized edema which can impact the legs and feet, while swelling specific to the lower extremities is often caused by poor circulation of blood or body fluids. Sometimes leg swelling can be a sign of a blood clot, or related to a medication side effect or serious malnutrition. While medical management of the underlying condition is essential, most of this swelling can also be improved by some home measures.

Step 1: Understand and Treat the Cause
Swelling happens for a reason, and for effective treatment, the cause has to be addressed. So if your swelling is a new symptom, it's important to alert your doctor and receive and follow your management plan. Treatment may include medications called diuretics, which help flush extra fluid out of your body.
Step 2: Elevate Your Legs
An effective way to manage lower extremity swelling is to elevate your feet 30 minutes at a time, several times a day. This practice can help this excess fluid flow away from the feet and legs and reduce swelling. It also works best if your feet are above heart level, which can be accomplished by lying down with your feet under a pillow.
Step 3: Apply Pressure
Swelling from a variety of causes can be improved by compression therapy, which is often accomplished by wearing support or compression stockings. These stockings apply pressure to keep fluid from collecting in your legs and feet. Since compression stockings are available in different pressure levels, ask your doctor which type is right for you. These may be prescribed, or purchased at a drug or medical supply store.
Step 4: Watch Your Diet
Sodium is a mineral important in fluid balance, although excess sodium can cause the body to retain water. So if you are prone to swelling, reducing dietary sodium can help. This can be accomplished by eating out less often, limiting processed, canned and boxed foods, and choosing low-sodium seasonings such as fresh herbs and salt-free spices. Staying well hydrated is important too, so most people with edema can drink plenty of water. However, when edema is related to liver, heart or kidney failure, talk to your doctor, as sometimes a fluid restriction is necessary.
Step 5: Stay Active
Lower extremity swelling can be aggravated by prolonged standing or sitting. If you have to stand for long hours at work, move around so you can shift your weight back and forth and take breaks to rest as able. If you have to sit for extended periods of time, at work or during travel, take short walks or exercise breaks to improve circulation. Leg and foot massage can also ease swelling and improve symptoms.
