Edema: Types, Causes, Symptoms, and Treatment

What is Edema?

Edema is swelling due to fluid collection in the tissues of the body. The lower legs and hands and the abdomen are some of the most prevalent swelling locations. It generally appears as puffiness and skin stretch.


This often happens in the legs (pedal edema) after being up and around, standing or sitting for lengthy periods of time and at the end of the day is more prominent. It can also accumulate over a lengthy period of time in the low back (sacral edema) after sitting or bed.

It may arise in the arms and hands, because of surgery, injury, or catheters in various body parts. This may occur in large vessels in the upper body following breast surgery, lymph gland surgery, or pacemaker or catheter placement.

What Are The Types of Edema

Pedal edema.

This occurs when the feet and lower legs gather fluid. If you are older or pregnant, it’s more prevalent. It can make moving around more difficult because you don’t have the same sensation in your feet.


The prevalent cause of this swelling in your arms and legs is damage to your lymph nodes, tissues that help your body’s filter germs and waste. Cancer treatments and radiation can cause damage. Cancer itself can also block lymph nodes and cause fluid buildup.


Peripheral edema.

This influences the legs, feet, and wrists, but it can also happen in the arms. It can be a sign of problems with the circulation system, lymph nodes, or kidneys.

Macular edema.

It happens when fluid accumulates the delicate tissue in a part of your eye-called macula that is in the center of the retina at the back of your eye. It happens when the ships are damaged and the fluid leaks.

Pulmonary edema.

You have pulmonary edema when fluid gathers in your lungs ‘ air sacs. That makes breathing difficult for you, and when you lie down, it’s worse. You may have a quick heartbeat, feel asphyxiated, and sometimes with blood, cough up as foamy spit.

Possible causes of edema

Edema may result from cardiovascular problems, infection, death of tissue, malnutrition, renal disease, an overload of full body fluid, and issues with electrolytes.

Kidney disease

kidney disorder might not be able to remove enough blood fluid and sodium. This places stress on the arteries, leading to leakage. There may be swelling around the legs and eyes.

Heart failure

If either one of the heart’s lower chambers is unable to pump blood correctly, the blood can build up in the limbs, triggering edema.


The body releases hormones during pregnancy that promote fluid retention, and a female tends to maintain more sodium and water than normal. The face may swell, hands, lower limbs, and feet.


Many types of food and bites of insects in individuals who are allergic or susceptible to them may trigger face or skin edema. Significant swelling may be a sign of anaphylaxis. Swelling in the throat can close the airway of a person, so they can’t breathe.

Liver disease

Cirrhosis impacts the functioning of the liver. This may result in alterations in hormone secretion and fluid-regulating substances, as well as decreased protein manufacturing. This leads liquid to leak into the adjacent tissue from the blood vessels.
