Is edema a sign of a serious condition?

Edema can be caused by something as simple as sitting too long, but it can also signal heart failure, kidney disease, or deep vein thrombosis. Persistent or worsening edema should always be evaluated by a doctor.

Can drinking more water help edema?

Staying properly hydrated can actually help reduce fluid retention. Dehydration can cause the body to hold onto water, so drinking adequate fluids while limiting sodium is often recommended.

Does edema go away on its own?

Mild edema from prolonged standing or a high-salt meal often resolves with rest and leg elevation. However, edema caused by an underlying medical condition typically requires treatment.

Edema

Also known as: Swelling, Fluid Retention, Dropsy

Edema is the medical term for swelling caused by excess fluid trapped in the body's tissues, most commonly in the legs, ankles, and feet. It can result from underlying conditions including heart failure, kidney disease, and venous insufficiency. While mild edema may resolve on its own, persistent or severe swelling requires medical evaluation to identify and treat the root cause.

Symptoms

Swelling in the legs, ankles, feet, or hands

Stretched or shiny skin over the swollen area

Skin that retains a dimple after being pressed (pitting edema)

Increased abdominal size

Stiff or aching joints

Weight gain from fluid retention

Difficulty breathing if fluid accumulates in the lungs

Causes

Heart failure reducing the heart's pumping efficiency
Kidney disease causing sodium and fluid retention
Liver cirrhosis affecting protein production
Venous insufficiency or blood clots in the legs
Certain medications such as calcium channel blockers and NSAIDs
Pregnancy-related hormonal changes

Risk Factors

Congestive heart failure
Chronic kidney disease
Prolonged sitting or standing
High sodium diet
Obesity
Pregnancy

Diagnosis

Physical examination assessing swelling location and severity
Blood tests including kidney function and albumin levels
Echocardiogram to evaluate heart function
Ultrasound of affected limbs to check for blood clots
Urinalysis to detect protein loss

Treatment

Diuretics (water pills) to remove excess fluid
Compression stockings for leg edema
Elevation of affected limbs above heart level
Reduced sodium intake
Treatment of the underlying condition causing edema

Prevention

Limit salt intake in your diet
Stay physically active and avoid prolonged sitting
Elevate your legs when resting
Wear compression stockings if recommended by your doctor

When to See a Doctor

Swelling occurs suddenly or in only one leg (may indicate a blood clot)
You experience shortness of breath along with swelling
Swelling is accompanied by chest pain
Edema does not improve with elevation and rest
