Elevating your feet above heart level is the single fastest way to relieve edema, and combining it with compression, movement, and dietary changes makes the relief last. Most mild to moderate foot swelling responds well to these home strategies, though persistent or sudden swelling can signal something that needs medical attention.
Elevate Your Feet Above Your Heart
Gravity is both the cause of and the simplest fix for foot edema. When you sit or stand for long periods, fluid pools in your lower legs because your veins and lymphatic system have to work against gravity to push it back up. Elevation reverses that equation.
The key detail most people miss: your feet need to be above the level of your heart, not just propped on an ottoman. Lying on a couch or bed with two or three pillows under your calves gets the angle right. Sitting in a recliner with your legs slightly elevated helps, but it’s less effective than lying down because your feet may still sit below your chest. Aim for 15 to 20 minutes at a time, and repeat several times throughout the day. Many people notice visible improvement within the first session, though chronic swelling takes days of consistent elevation to meaningfully reduce.
Use Compression Stockings
Compression stockings apply graduated pressure, tightest at the ankle and lighter toward the knee, which helps push fluid upward and prevents it from settling back into your feet. They’re the primary treatment for chronic venous insufficiency, one of the most common causes of persistent foot edema.
Compression levels are measured in millimeters of mercury (mmHg), and the right level depends on how severe your swelling is:
- 15 to 20 mmHg (mild): Good for early or occasional swelling, long flights, or jobs that keep you on your feet. Available over the counter without a prescription.
- 20 to 30 mmHg (moderate): The most commonly prescribed level for mild to moderate edema. This is what most people with recurring foot swelling end up using daily.
- 30 to 40 mmHg (firm): Recommended for more stubborn swelling, especially when lower levels haven’t been enough, or when edema is complicated by skin changes or ulceration.
- 40 to 50 mmHg and above: Reserved for severe cases, typically only used after a clinical assessment.
Put compression stockings on first thing in the morning before swelling has a chance to build up. If your feet are already swollen, elevate them for 15 to 20 minutes first, then put the stockings on. Wearing them over already-swollen feet is uncomfortable and less effective.
Do Ankle Pumps and Calf Exercises
Your calf muscles act as a pump for your veins. Every time they contract, they squeeze blood and fluid upward toward your heart. When you sit still for hours, that pump shuts off, and fluid accumulates. Ankle pumps are the simplest way to restart it.
Sit or lie down with your legs extended in front of you. Point your toes toward your knees as far as you comfortably can, then point them away from you. Alternate back and forth for two to three minutes, repeating two to three times per hour. You can do these at a desk, on a plane, or in bed. Some soreness is normal, but stop if you feel sharp or increasing pain.
Walking is even better. A 10 to 15 minute walk engages your full calf muscle and creates stronger pumping action than ankle exercises alone. If mobility is limited, even wiggling your toes and rotating your ankles in circles helps move fluid. The goal is to avoid staying completely still for more than 30 to 60 minutes at a stretch.
Cut Back on Sodium
Sodium makes your body hold onto water. The more salt you eat, the more fluid your tissues retain, and gravity pulls that extra fluid straight to your feet. Reducing your sodium intake is one of the most effective long-term strategies for managing edema.
For people with fluid retention, most major medical organizations recommend keeping sodium below 2,000 mg per day. That’s roughly one teaspoon of table salt, but the real challenge is hidden sodium in processed and restaurant food. A single fast-food meal can contain more than 2,000 mg on its own. Canned soups, deli meats, frozen meals, bread, condiments, and cheese are common culprits.
Reading nutrition labels is the most practical first step. Swap canned vegetables for fresh or frozen (no sauce), season with herbs and spices instead of salt, and cook at home more often where you control what goes in. Most people start noticing less swelling within a few days of cutting sodium, especially if their intake was high to begin with. Drinking plenty of water alongside a lower-sodium diet also helps your kidneys flush excess fluid more efficiently.
When Swelling Points to Something Bigger
Foot edema isn’t always just a nuisance from standing too long. It can be a visible sign of an underlying condition. The pattern of the swelling often reveals what’s going on.
Swelling in both feet that develops gradually is more likely tied to a systemic cause: heart disease, kidney problems, liver conditions, or medication side effects. Calcium channel blockers (commonly prescribed for blood pressure), certain diabetes medications, and anti-inflammatory drugs like ibuprofen are frequent offenders. Pregnancy, hormonal fluctuations before a period, and being significantly overweight also cause bilateral foot swelling.
Swelling in only one foot or leg is a different story and warrants quicker attention. A blood clot in a deep vein, an infection like cellulitis, or chronic venous insufficiency (where valves in your leg veins stop working properly) can all cause one-sided swelling. Sudden swelling in one leg, especially with warmth, redness, or pain, should be evaluated promptly.
Generalized edema, where swelling appears in multiple parts of your body at once, is the most concerning pattern. It often reflects a problem with the heart, kidneys, or liver that needs treatment beyond elevation and compression.
What About Diuretics?
Diuretics, often called water pills, work by making your kidneys excrete more sodium and water. They’re commonly prescribed when edema is linked to heart failure, kidney disease, or liver problems. Loop diuretics are the most frequently used type for peripheral edema.
However, diuretics aren’t appropriate for every type of foot swelling. For chronic venous insufficiency, the most common cause of persistent lower leg edema, guidelines specifically recommend against diuretics unless you also have a condition like heart failure that requires them. Compression and elevation are preferred because diuretics don’t fix the underlying valve problem and can cause side effects like dehydration, low potassium, and dizziness. If your doctor hasn’t identified a systemic cause for your swelling, mechanical approaches (elevation, compression, movement) are almost always the right first step.
A Daily Routine That Works
Combining these strategies into a consistent routine makes a bigger difference than relying on any single one. Put compression stockings on in the morning before getting out of bed. During the day, take short walking breaks every 30 to 60 minutes and do ankle pumps whenever you’re sitting for extended periods. In the evening, lie down and elevate your feet above your heart for 15 to 20 minutes. Keep daily sodium under 2,000 mg.
For many people, this combination controls foot edema well enough that it stops interfering with daily life. If swelling doesn’t improve after a week or two of consistent effort, or if it’s getting progressively worse, that’s a signal something beyond simple fluid pooling may be happening, and it’s worth getting checked out.
