Swollen ankles improve with a combination of elevation, movement, compression, and dietary changes. For most people, the swelling comes from fluid pooling in the lower legs due to gravity, prolonged sitting or standing, or excess sodium intake. The fix is straightforward: help your body move that fluid back up and out.
Elevate Your Legs Above Your Heart
The single most effective thing you can do right now is lie down and raise your legs above heart level. This reverses gravity’s pull on the fluid that’s settled in your ankles. Prop your legs on a stack of pillows, a cushion against a wall, or the arm of a couch so your feet sit higher than your chest. Hold this position for 15 to 20 minutes, and repeat several times throughout the day.
If you can’t get your legs fully above heart level, resting them on an ottoman, coffee table, or sofa still helps by slowing the downward pull of gravity. Even partial elevation makes a noticeable difference, especially if you’ve been sitting or standing for hours.
Use Your Calf Muscles as a Pump
Your calf muscles act as a built-in pump for your veins. Every time they contract, they squeeze blood and fluid upward toward your heart. When you sit still for long stretches, that pump shuts off and fluid accumulates around your ankles.
Ankle pumps are the simplest way to restart it. Point your toes down, then pull them up toward your shin. Repeat this motion for two to three minutes, and do it two to three times per hour when you’re sitting or lying down. You can do these at your desk, on a plane, or in bed. Walking is even better if you’re able. A short five-to-ten-minute walk engages the full calf pump cycle and can visibly reduce swelling within an hour.
Try Compression Socks or Stockings
Compression stockings apply graduated pressure to your lower legs, tightest at the ankle and gradually loosening toward the knee or thigh. This steady squeeze prevents fluid from settling and supports your veins in pushing blood back up.
Compression garments come in four classes based on how much pressure they deliver, measured in millimeters of mercury (mmHg). Class I stockings apply 18 to 21 mmHg and work well for mild, everyday swelling from sitting or standing too long. Class II (23 to 32 mmHg) is common for moderate swelling or varicose veins. Classes III and IV deliver stronger pressure and are typically prescribed for more serious venous or lymphatic conditions.
For general use, you can buy Class I stockings over the counter at most pharmacies. Put them on first thing in the morning before swelling builds up during the day. If your swelling is more persistent, a doctor can prescribe a higher compression class based on your specific situation.
Cut Back on Sodium
Sodium makes your body hold onto water, and that extra fluid often shows up first in your ankles. Most health organizations recommend keeping sodium below 2,000 milligrams per day if you’re dealing with fluid retention. The average American consumes well over 3,000 mg daily, so there’s usually room to cut back significantly.
The biggest sources aren’t the salt shaker. Processed foods, canned soups, deli meats, frozen meals, bread, and restaurant dishes account for the vast majority of sodium intake. Reading labels and cooking more meals at home gives you the most control. Potassium-rich foods like bananas, sweet potatoes, and leafy greens help your kidneys flush excess sodium, which can further reduce fluid retention.
Stay Hydrated (Yes, Really)
It sounds counterintuitive, but drinking enough water actually helps reduce swelling. When you’re dehydrated, your body holds onto fluid as a protective measure. Staying consistently hydrated signals your kidneys to release excess water and sodium. Aim for steady intake throughout the day rather than large amounts at once.
When Swelling Points to Something Bigger
Most ankle swelling is harmless and responds to the measures above. But certain patterns signal a medical issue that needs attention.
Swelling in only one leg, especially if it’s accompanied by warmth, redness, or pain in the calf, can indicate a blood clot in the deep veins. This requires urgent evaluation. Swelling that affects both legs and doesn’t improve with elevation can be linked to heart failure, kidney disease, liver problems, thyroid disorders, or chronic venous insufficiency. Each of these conditions causes fluid buildup through different mechanisms, from weakened heart pumping to low protein levels in the blood to damaged vein valves, but the visible result is the same: persistent puffiness in the lower legs.
If your swelling developed suddenly, leaves a deep dent when you press on it that takes more than 15 seconds to bounce back, or comes with shortness of breath, you need medical evaluation promptly. Pressing your thumb into the swollen area is a quick self-check. A shallow 2 mm indent that bounces right back is mild (Grade 1 on the clinical scale). An 8 mm pit that takes two to three minutes to refill is Grade 4 and suggests significant fluid overload.
Swollen Ankles During Pregnancy
Some ankle swelling during pregnancy is completely normal, particularly in the third trimester. Your body carries extra blood volume, your growing uterus compresses the veins returning blood from your legs, and hormonal changes make your blood vessels more permeable to fluid. Elevation, compression stockings, and walking all help.
The concern is preeclampsia, a serious pregnancy complication. Its early signs include high blood pressure, protein in urine, and sudden fluid retention that causes rapid weight gain and swelling in the hands, ankles, and face. Swelling alone doesn’t mean preeclampsia, but swelling that comes on quickly, especially in your face and hands along with your ankles, warrants a call to your provider. Headaches, vision changes, or upper abdominal pain alongside swelling are more urgent warning signs.
A Daily Routine That Works
If swollen ankles are a recurring problem, building a few habits into your day makes the biggest difference. Put on compression stockings before you get out of bed. Take short walking breaks every 30 to 60 minutes if you sit for work. Do ankle pumps during any period of prolonged sitting. Elevate your legs for 15 to 20 minutes when you get home. Keep your sodium under 2,000 mg and drink water consistently.
Most people who commit to this combination notice a meaningful reduction within a few days. If the swelling persists despite these changes, or if it’s getting progressively worse, that’s a sign your body may be dealing with something beyond simple fluid pooling, and it’s worth getting checked out.
