Edema is a medical condition that happens when fluid gets trapped in the body's tissues. It occurs most commonly in the legs, ankles, and feet but can also affect other areas, from the face to the abdomen. Treatment for edema depends on the root cause, which needs to be determined by a medical care professional. The following guide explains more about this condition, including its causes and treatment.

What Is Edema?

Edema refers to swelling in the body due to fluid retention. There are different types of edema. Pedal edema impacts the feet and lower legs, while peripheral edema can affect the lower or upper extremities. Edema in the lower limbs can make your legs feel heavy, leading to difficulty walking. Edema may also be accompanied by ulcers due to the decreased blood flow it causes.

What Causes It?

Diseases such as thyroid conditions, congestive heart failure, and kidney issues can cause edema, as can allergic reactions, trauma, and blood clots. Edema can also occur in older persons as the valves of the veins in the leg weaken, resulting in varicose veins and fluid buildup in the legs. 

Certain habits increase the risk of edema, including a sedentary lifestyle and a diet high in salt. Pregnant women are also at a higher risk of the condition.

How Is It Treated?

The treatment for edema depends on the root cause. For example, if a patient's edema is exacerbated by a certain medication, a medical care professional can propose an alternative drug. Lifestyle changes like quitting smoking, losing weight, reducing salt intake, and drinking less alcohol can also help. 

People struggling with edema in their legs can help their situation by keeping a pillow under their legs when sitting down and wearing support stockings. A physician can advise on possible solutions depending on your unique case.
