Swollen feet and ankles usually respond well to a combination of elevation, movement, compression, and dietary changes. For most people, the swelling comes from fluid pooling in the lower legs after prolonged sitting or standing, and simple at-home strategies can bring noticeable relief within hours. The key is figuring out whether your swelling is a temporary nuisance or a signal that something deeper needs attention.
Elevate Your Legs Above Your Heart
The single fastest way to reduce swelling is to lie down and prop your legs on pillows so they sit above the level of your heart. Gravity does the work, pulling trapped fluid back toward your core where your body can process and eliminate it. Aim for about 15 minutes per session, three to four times a day. If you only do it once at bedtime, you’ll still see improvement by morning, but spreading sessions throughout the day works significantly better.
A common mistake is sitting in a recliner with your feet at hip height and calling it “elevation.” That’s not enough. Your ankles need to be higher than your chest for fluid to drain effectively. Lying flat on a couch or bed with two or three pillows stacked under your calves gets you into the right position.
Use Ankle Pumps and Gentle Movement
Your calf muscles act as a natural pump that pushes fluid upward through your veins. When you sit or stand in one position for hours, that pump goes idle, and fluid settles into your feet. Ankle pumps are the simplest way to restart it: point your toes down toward the floor, then pull them back up toward your shin. Repeat this motion for two to three minutes, and do it two to three times every hour when you’re sedentary.
Walking is even more effective because it engages the full calf muscle with each step. Even a five-minute walk around the office or house every hour can prevent swelling from building up. Swimming and cycling are particularly good options if you’re dealing with chronic ankle swelling, since they combine movement with gentle external pressure from water or reduced gravitational load.
Try Compression Socks
Compression stockings apply graduated pressure to your lower legs, tightest at the ankle and looser toward the knee, which helps push fluid upward and prevents it from pooling. They come in different pressure levels measured in millimeters of mercury (mmHg):
- 15 to 20 mmHg: Good for mild, occasional swelling from travel, long days on your feet, or desk work.
- 20 to 30 mmHg: Better for moderate swelling, varicose veins, or post-surgical recovery.
- 30 to 40 mmHg: Used for chronic venous insufficiency, lymphedema, or severe varicose veins. This level typically requires a fitting or recommendation from a provider.
Put compression socks on first thing in the morning before swelling starts. If you wait until your ankles are already puffy, the socks are harder to get on and less effective. Knee-high styles work for most people. Avoid wearing them to bed unless specifically told otherwise, since lying flat already reduces the fluid pressure that compression is designed to counteract.
Cut Back on Sodium
Sodium makes your body hold onto water, and excess salt intake is one of the most common contributors to puffy ankles. A reasonable target is staying under 2,000 milligrams of sodium per day. For context, a single fast-food meal can easily exceed that entire daily limit.
The biggest sources of hidden sodium aren’t the salt shaker on your table. They’re processed and packaged foods: canned soups, deli meats, frozen dinners, soy sauce, bread, and restaurant meals. Reading nutrition labels and cooking more meals at home gives you the most control. Potassium-rich foods like bananas, sweet potatoes, and spinach can help your kidneys flush excess sodium more efficiently.
Check Your Medications
Several common medications cause ankle swelling as a side effect. Blood pressure drugs called calcium channel blockers are among the most frequent culprits, with ankle swelling affecting anywhere from 1 to 15 percent of people taking them. Unlike typical fluid retention, the swelling these drugs cause comes from fluid shifting out of blood vessels into surrounding tissue rather than your body holding onto extra water. That’s why diuretics (water pills) often don’t help with this type of swelling.
Other medications that can cause puffy ankles include certain diabetes drugs, steroids, hormone therapies (including estrogen and testosterone), and some antidepressants. If your swelling started or worsened after beginning a new medication, that connection is worth raising with your prescriber. Stopping or switching medications on your own can be dangerous, but your doctor may be able to adjust your regimen. For calcium channel blockers specifically, adding a second blood pressure medication from a different class has been shown to cut swelling rates from nearly 19 percent down to about 8 percent.
Why Your Feet Swell in the First Place
Swelling happens when fluid leaks out of small blood vessels and gets trapped in the tissue around your ankles and feet. Gravity pulls that fluid downward throughout the day, which is why swelling tends to be worse by evening and better in the morning after a night of lying flat.
Common, non-serious causes include standing or sitting for long periods, eating a salty meal, hot weather (which dilates blood vessels), and pregnancy. Carrying extra body weight also increases pressure on the veins in your legs and makes it harder for fluid to return to your heart efficiently.
More serious causes involve the organs responsible for managing fluid in your body. When the heart isn’t pumping effectively, it can’t pull blood back from the extremities efficiently, and the kidneys respond by holding onto extra salt and water, compounding the problem. Kidney disease directly impairs your body’s ability to filter and excrete fluid. Liver disease reduces production of a key blood protein that keeps fluid inside your blood vessels, allowing it to leak into surrounding tissue. Damaged or weakened veins in the legs, known as chronic venous insufficiency, let blood pool downward instead of returning to the heart.
How to Tell If Swelling Is Serious
You can do a quick self-check by pressing your thumb firmly into the swollen area for about five seconds and then releasing. If the skin bounces right back, the swelling is mild. If your thumb leaves an indentation that takes 15 seconds to fill back in, that’s moderate. Indentations lasting 30 seconds or more suggest more significant fluid accumulation that warrants medical evaluation.
Certain patterns call for prompt medical attention. Swelling in only one leg, especially if it’s accompanied by redness, warmth, or pain, could signal a blood clot. Swelling paired with shortness of breath may point to a heart or lung problem. Other warning signs that should prompt a call to your doctor include severe pain in the swollen area, fever, coughing or vomiting blood, yellowing of the skin or eyes, and swelling that appears suddenly in the face and hands during pregnancy (a possible sign of preeclampsia). Widespread swelling from an allergic reaction, particularly around the face or throat, is a medical emergency requiring immediate help.
Swelling During Pregnancy
Some degree of foot and ankle swelling is completely normal during pregnancy, particularly in the third trimester. The growing uterus puts pressure on the veins that return blood from your legs, and your body retains more fluid overall to support the baby. Elevation, compression socks, staying active, and reducing sodium all help.
What’s not normal is a sudden onset of swelling, especially in your face and hands. Rapid, unexplained weight gain alongside new swelling can be an early sign of preeclampsia, a serious pregnancy complication involving high blood pressure. If your swelling changes dramatically over a day or two rather than building gradually over weeks, contact your obstetric provider right away.
Building a Daily Routine for Chronic Swelling
If swollen ankles are a recurring part of your life, consistency matters more than any single intervention. A practical daily routine looks something like this: put on compression socks before getting out of bed, take short walking breaks every hour during the day, elevate your legs for 15 minutes in the morning, afternoon, and evening, and keep your sodium intake under 2,000 milligrams. Staying well-hydrated also helps, since dehydration actually triggers your body to retain more fluid rather than less.
Losing even a modest amount of weight, if you’re carrying extra, can meaningfully reduce the venous pressure in your legs and improve swelling over time. And while it sounds counterintuitive, drinking more water throughout the day helps your kidneys flush sodium and reduce overall fluid retention. Most people see the biggest improvements when they combine three or four of these strategies together rather than relying on any single one.
