Overview

Edema is swelling caused by extra fluid trapped in your body's tissues. It often happens in the feet, ankles, and legs because of heart or circulation problems.

Yes, edema is common, especially in people with heart failure or venous insufficiency.

It affects people of all ages but is more common in older adults and those with chronic heart or kidney conditions.

Symptoms

Common symptoms

• Swelling in feet, ankles, legs, or hands
• Puffiness in the face or abdomen
• Skin that feels tight or looks shiny
• Indentation when pressed (pitting edema)

Symptoms in children

• Swelling around the eyes or in the legs
• Unexplained weight gain
• Less energy than usual

Symptoms in older adults

• Swelling that gets worse during the day
• Difficulty putting on shoes
• Shortness of breath when lying flat

Causes

Main causes

• Heart failure (weak heart pumping)
• Kidney disease
• Liver disease
• Venous insufficiency (weak valves in leg veins)
• Medicines (like blood pressure drugs)
• Pregnancy

Risk factors

• Being overweight
• Sitting or standing for long periods
• High salt intake
• Age over 60
• History of heart disease

When to see a doctor

See a doctor urgently if:

• If you have sudden, severe swelling
• If swelling is accompanied by shortness of breath
• If you have chest pain or pressure

Book a routine appointment if:

• If swelling lasts more than a few days
• If you notice new swelling in your legs or feet
• If you have a known heart condition and swelling changes

Diagnosis

Your doctor will ask about your symptoms and medical history, and examine the swollen area. They may press on the skin to see if an indentation remains.

Tests that may be done

• Blood tests (to check kidney, liver, and heart function)
• Urine test
• Echocardiogram (ultrasound of the heart)
• Electrocardiogram (ECG)
• Venous ultrasound (to check leg veins for clots)

What to expect at your appointment

Most tests are painless and can be done in a clinic or hospital. You may be asked to avoid eating or drinking for a few hours before some tests.

Treatment

Treatment focuses on the underlying cause of edema. For heart-related edema, doctors often recommend reducing salt intake and taking medicines to help remove excess fluid.

Self-care at home

• Elevate your legs above heart level when resting
• Reduce salt in your diet
• Wear compression stockings if recommended by a doctor
• Move your legs frequently if you sit or stand for long periods

Medical treatments

Diuretics (water pills) are commonly used to help your body get rid of extra fluid. Other medicines may be given to improve heart function. Fluid removal procedures (like paracentesis for belly swelling) may be needed in severe cases.

When is surgery considered?

Surgery is rarely needed for edema itself. However, if edema is caused by a blocked vein or heart valve problem, surgery may be considered to fix that issue.

Living with this condition

Living with edema means paying attention to your body and managing fluid levels. Daily leg elevation, skin care to prevent infection, and following your treatment plan are important.

Lifestyle tips

• Limit salt intake
• Stay active with light exercise like walking
• Avoid standing or sitting for too long without breaks
• Wear comfortable shoes

Diet and exercise

A low-salt diet helps control fluid buildup. Aim for 5-6 grams of salt per day or as advised by your doctor. Regular gentle exercise, like walking or swimming, improves circulation.

Mental health and emotional wellbeing

Edema can affect your self-image and cause frustration. It's normal to feel worried or down. Talk to your doctor or a counselor if you need support.

Prevention

Some causes of edema cannot be prevented, but you can reduce your risk by managing conditions like high blood pressure, heart disease, and diabetes. A healthy lifestyle helps.

Vaccines

Getting recommended vaccines, such as flu and pneumonia shots, can help prevent infections that might worsen edema in people with heart disease.

Screening programmes

Regular check-ups for blood pressure, kidney function, and heart health can catch problems early.

Complications

If left untreated

• Pulmonary edema (fluid in the lungs, causing difficulty breathing)
• Skin ulcers or infections in swollen areas
• Reduced mobility
• Worsening of underlying heart or kidney disease

Long-term outlook

With proper treatment and self-care, most people can manage edema well and improve their quality of life. The outlook depends on the underlying cause, but advances in medicine offer many options.
