Elevating your legs, wearing compression stockings, cutting back on sodium, and staying active are the most effective ways to reduce leg swelling. Most mild swelling responds well to these strategies within days, though the right approach depends on what’s causing the fluid buildup in the first place.
Elevate Your Legs Above Your Heart
The simplest and fastest way to get relief is elevation. Gravity pulls fluid down into your lower legs throughout the day, and reversing that pull drains it back toward your core. The key detail most people miss: your legs need to be above the level of your heart, not just propped on an ottoman. Lying on your back with your legs up on a stack of pillows or resting them against a wall works well.
Aim for about 15 minutes at a time, three to four times a day. If you can only manage it once, doing it before bed still helps. Many people notice visible improvement after a single session, especially if the swelling is mild and related to prolonged sitting or standing.
Use Compression Stockings
Compression stockings apply graduated pressure to your legs, squeezing tightest at the ankle and gradually loosening toward the knee or thigh. This steady pressure keeps fluid from pooling and helps push it back into circulation.
Stockings come in three general pressure ranges. Low compression (under 20 mmHg) is available without a prescription and works well if your swelling comes from long days on your feet, sitting at a desk, or pregnancy. Medium compression (20 to 30 mmHg) and high compression (above 30 mmHg) require a prescription and are used for more persistent swelling or chronic venous problems.
Put them on first thing in the morning before swelling has a chance to build. If you wait until your legs are already puffy, the stockings are harder to get on and less effective. Replace them every three to six months, since the elastic loses its pressure over time.
Get Your Calf Muscles Working
Your calf muscles act as a built-in pump for the veins in your lower legs. Every time you flex your calf, the muscle contraction redirects blood from the superficial veins near the surface into deeper veins, pushing it back up toward your heart. When you sit or stand still for hours, that pump sits idle and fluid accumulates.
Walking is the most natural way to activate this pump. Even a five-minute walk every hour makes a noticeable difference. If walking isn’t an option, ankle pumps work too: sit with your legs extended and repeatedly point your toes down, then pull them back toward your shin. This engages both the calf and the muscles along the front of your lower leg, mimicking the pumping action of walking. Doing 20 to 30 repetitions several times a day keeps fluid moving.
Reduce Your Sodium Intake
Sodium makes your body hold onto water. The more salt in your bloodstream, the more fluid your kidneys retain to keep concentrations balanced. For people with chronic swelling, guidelines from Georgetown University’s Department of Medicine recommend limiting sodium to 1,375 to 1,800 mg per day, which is significantly lower than what most people eat.
The biggest sources of sodium aren’t the salt shaker. Processed foods, canned soups, deli meats, soy sauce, and restaurant meals account for the majority of sodium in most diets. Reading nutrition labels and cooking more meals at home are the two most practical changes you can make. Even modest reductions, like switching from canned to fresh vegetables or rinsing canned beans, can lower your daily intake enough to see a difference in swelling within a week or two.
Stay Hydrated, Don’t Restrict Water
It sounds counterintuitive, but drinking enough water actually helps reduce fluid retention rather than making it worse. When you’re dehydrated, your blood becomes more concentrated with sodium and other minerals. Your brain responds by releasing a hormone that tells your kidneys to hold onto every drop of fluid they can, which worsens swelling.
Drinking water consistently throughout the day keeps that sodium ratio balanced so your kidneys can release fluid normally. You don’t need to force excessive amounts. Sipping steadily rather than chugging large quantities at once also helps, since your body has protective mechanisms that dump excess fluid quickly when you drink too much at once, which can throw off your electrolyte balance.
Check Whether Your Medications Are Contributing
Some common medications cause leg swelling as a side effect. Calcium channel blockers, a widely prescribed class of blood pressure medication, are one of the most frequent culprits. Ankle swelling occurs in 1 to 15% of people taking these drugs at standard doses, and the incidence can exceed 80% in people on high doses long-term. The swelling is dose-related, meaning it often gets worse as the dose goes up.
Other medications that can cause fluid retention include certain diabetes drugs, steroids, and hormonal treatments like estrogen. If your swelling started or worsened after beginning a new medication, that connection is worth discussing with the prescriber. Adjusting the dose or switching to a different drug in the same class often resolves the problem.
Chronic Venous Disease as an Underlying Cause
Chronic venous disease affects over 25 million adults in the United States. It happens when the valves inside your leg veins weaken and allow blood to flow backward and pool, causing persistent swelling along with aching, heaviness, itching, and sometimes skin changes or ulcers. If your swelling keeps coming back despite elevation and compression, damaged veins may be the root cause.
Conservative treatment with compression stockings and regular movement remains the first-line approach. For people who don’t get enough relief, the 2025 clinical guidelines from the Society for Cardiovascular Angiography and Interventions recommend minimally invasive procedures like vein ablation or sclerotherapy as additions to conservative care. These are outpatient treatments with relatively quick recovery times, typically allowing a return to normal activity within a few days.
Swelling in One Leg vs. Both Legs
The pattern of your swelling carries important diagnostic information. Swelling in both legs at roughly the same level usually points to a systemic cause: heart, kidney, or liver problems, or a medication side effect. Swelling in just one leg raises the concern for something more localized, including deep vein thrombosis (DVT), a blood clot that can be dangerous if it breaks loose and travels to the lungs.
DVT symptoms include sudden swelling in one leg, pain or tenderness that worsens when you stand or walk, warmth in the swollen area, reddish or discolored skin, and veins that appear larger than usual near the surface. These symptoms together, especially if they come on quickly, warrant immediate medical attention. A blood clot is not something to monitor at home.
Swelling that doesn’t cause pain when you press on it is more typical of lymphedema, where the lymphatic drainage system isn’t functioning properly. Painful, tender swelling is more associated with clots or infection. Both deserve evaluation, but the urgency is different.
Putting It All Together
For most people dealing with mild to moderate leg swelling, the combination of daily elevation, compression stockings, regular movement, and sodium reduction produces meaningful improvement within one to two weeks. These strategies work best together rather than in isolation. Elevating your legs drains the fluid that’s already there. Compression and calf exercises prevent new fluid from pooling. Cutting sodium reduces the amount of fluid your body retains in the first place.
If swelling persists despite consistent effort with these measures, or if it’s accompanied by shortness of breath, chest pain, or sudden one-sided swelling with warmth and redness, the underlying cause needs medical investigation rather than home management alone.
