Swollen feet usually improve with a combination of elevation, movement, compression, and dietary changes. Most cases stem from fluid pooling in the tissues of your lower legs due to gravity, prolonged sitting or standing, excess salt intake, or medication side effects. The right approach depends on what’s causing the swelling, but several strategies work across nearly all situations.
Elevate Your Legs Above Your Heart
The single fastest way to reduce swollen feet is to lie down and prop your legs up so they’re positioned above the level of your heart. This lets gravity work in your favor, draining fluid back toward your core instead of letting it pool around your ankles. Use a stack of pillows, a wedge cushion, or the arm of a couch. Aim for about 15 minutes at a time, three to four times throughout the day. Even one session brings noticeable relief, but consistency matters more than duration for keeping swelling down over time.
Move Your Feet and Ankles Often
Your calf muscles act as a pump that pushes blood and fluid upward through your veins. When you sit or stand still for long stretches, that pump barely works, and fluid collects in your feet. Simple ankle pumps are one of the most effective countermeasures: point your toes away from you, then pull them back toward your shin, moving through the full range of motion at a quick pace. Do at least 10 repetitions every hour you’re awake.
Walking is equally effective. Even a short five-minute walk activates the calf pump and gets fluid circulating. If your job keeps you at a desk or on your feet in one spot, set a timer to remind yourself to move. Calf raises (lifting your heels off the ground while standing) and toe raises work well when walking isn’t an option.
Try Compression Stockings
Compression stockings apply graduated pressure to your lower legs, helping veins and lymphatic vessels push fluid back up instead of letting it settle in your feet. They come in several pressure levels, measured in mmHg:
- 15 to 20 mmHg (mild) works for early or mild swelling, prevention during travel, and people who are new to compression and need to build tolerance.
- 20 to 30 mmHg (moderate) is the most common range for daily wear when you need a balance of effectiveness and comfort. It’s also used for post-injury or post-surgical swelling.
- 30 to 40 mmHg (firm) is reserved for more significant swelling, particularly in the lower legs where gravitational load is higher, or when moderate compression isn’t holding swelling at bay.
Put them on first thing in the morning before swelling has a chance to develop. Check throughout the day for redness, numbness, tingling, or pressure marks. If the top band rolls down or feels like it’s cutting in, the size or style is wrong. Higher pressure isn’t the fix for a poorly fitting stocking.
Cut Back on Sodium
Excess salt causes your body to hold onto water, and that extra fluid often shows up in your feet and ankles first. The Heart Failure Society of America recommends limiting sodium to 2,000 mg per day for people managing fluid retention. That’s less than a single teaspoon of table salt. Most of the sodium in a typical diet comes from processed foods, restaurant meals, canned soups, deli meats, and condiments rather than the salt shaker on your table. Reading nutrition labels and cooking more meals at home gives you the most control.
Drinking plenty of water also helps. It sounds counterintuitive, but a well-hydrated body is actually less likely to retain fluid. When you’re dehydrated, your body holds onto whatever water it has. Staying hydrated helps your kidneys flush excess sodium more efficiently.
Check Your Medications
Several common medications cause or worsen foot swelling as a side effect. Blood pressure drugs in the calcium channel blocker family are among the most frequent culprits. Ankle swelling from these medications is dose-related: at lower doses, it affects 1 to 15% of patients, but at high doses taken long-term, the incidence can exceed 80%. Women, older adults, and people in warm climates are especially susceptible. Unlike typical fluid retention, this type of swelling happens because the drug causes fluid to leak from capillaries into surrounding tissue.
Other medication classes linked to swelling include common pain relievers like ibuprofen and naproxen, corticosteroids, nerve pain medications like gabapentin and pregabalin, hormone therapies (estrogen, progesterone, testosterone), some blood pressure drugs beyond calcium channel blockers (beta blockers, hydralazine), and certain antipsychotic and antidepressant medications. If your swelling started or worsened around the time you began a new medication, that connection is worth discussing with whoever prescribed it. Don’t stop a medication on your own, but a dose adjustment or switch to a different drug often resolves the problem.
When Swelling Signals Something Serious
Most swollen feet are harmless and respond well to the strategies above. But certain patterns warrant prompt medical attention.
Swelling in only one leg, especially if it comes with pain or cramping that starts in the calf, warmth, or a change in skin color to red or purple, may indicate a deep vein thrombosis (a blood clot in a deep vein). DVT can sometimes produce no symptoms at all. If a clot breaks loose and travels to the lungs, it becomes a pulmonary embolism, which is life-threatening. Warning signs include sudden shortness of breath, chest pain that worsens with deep breathing or coughing, dizziness, fainting, rapid pulse, or coughing up blood. Any of these requires emergency care.
During pregnancy, some swelling in the feet and ankles is completely normal. What’s not normal is sudden swelling, particularly in the face and hands, combined with rapid weight gain. These can be signs of preeclampsia, a serious condition marked by high blood pressure and organ stress. Severe headaches, blurred vision, intense abdominal pain, or severe shortness of breath during pregnancy also call for immediate medical evaluation.
Chronic Swelling and Underlying Conditions
When foot swelling persists for weeks or months despite home measures, an underlying condition is usually driving it. Chronic venous insufficiency, where the valves in your leg veins weaken and allow blood to flow backward, is one of the most common causes. Lymphedema, a buildup of lymph fluid due to damage or blockage in the lymphatic system, is another. Heart failure, kidney disease, liver disease, and thyroid disorders can all produce ongoing bilateral swelling.
For these conditions, treatment goes beyond elevation and compression. Prescription water pills (diuretics) help the kidneys remove excess fluid when swelling is tied to heart, kidney, or liver problems. The specific type and dose depends on the underlying diagnosis. Compression therapy becomes a long-term management tool rather than a quick fix, and sodium restriction shifts from a helpful tip to a core part of daily life.
Lipedema, a condition involving abnormal fat deposits that primarily affects the legs, is frequently misdiagnosed as simple swelling or obesity. It almost exclusively affects women and doesn’t respond to typical edema treatments like elevation or diuretics, though compression can help manage discomfort. If your legs swell symmetrically but your feet are spared, and the swelling doesn’t improve with standard measures, lipedema is worth investigating.
