Swollen hands and feet usually respond well to a combination of elevation, movement, dietary changes, and compression. The swelling happens when fluid leaks out of your blood vessels and collects in the surrounding tissue faster than your lymphatic system can drain it away. Most cases stem from something temporary like prolonged sitting, heat, high salt intake, or pregnancy, but persistent or sudden swelling can signal a more serious underlying condition that needs medical attention.
Why Fluid Builds Up in Your Hands and Feet
Your body constantly moves fluid between your bloodstream and the tissue around it. This exchange is controlled by pressure inside your blood vessels and the concentration of proteins in your blood. Swelling occurs when something tips that balance: higher pressure in the vessels pushes more fluid out, lower protein levels in the blood fail to pull fluid back in, or the lymphatic vessels that normally drain excess fluid become blocked or overwhelmed.
Gravity plays a major role, which is why your feet and ankles swell more than other body parts after a long day of standing or sitting. Your hands can swell for similar reasons during exercise, in hot weather, or when your arms hang at your sides for extended periods. Hormonal shifts during menstruation or pregnancy also increase fluid retention throughout the body.
Elevation and Positioning
The simplest and most effective first step is raising the swollen area above the level of your heart. For swollen feet, this means lying down and propping your legs on pillows. For swollen hands, rest them on a cushion at chest level or higher. Doing this several times a day helps gravity pull trapped fluid back toward your core where it can re-enter circulation. Elevating your legs while you sleep can also reduce morning puffiness and prevent fluid from pooling overnight.
Movement That Pushes Fluid Out
Your muscles act as pumps. Every time they contract, they squeeze the veins and lymphatic vessels running through them, pushing fluid upward and out of your extremities. When you sit or stand still for hours, those pumps aren’t working, and fluid accumulates.
For swollen feet and ankles, one of the most effective exercises is simply pointing your toes down and then pulling them up toward your shin, alternating back and forth for five to ten minutes. You can do this seated at a desk, on a plane, or lying in bed. Circular ankle rotations work well too. For swollen hands, repeatedly making a fist and then spreading your fingers wide helps activate the muscles in your forearm that drive fluid drainage. Even a short walk engages enough muscle groups to noticeably reduce lower-leg swelling.
If you have a job that keeps you seated, set a reminder to stand and walk for a few minutes every hour. If your job keeps you on your feet, take sitting breaks with your legs elevated when possible.
Cutting Back on Salt
Sodium makes your body hold onto water. When you eat a salty meal, your kidneys retain extra fluid to keep your blood’s sodium concentration in balance, and some of that fluid ends up in your tissues. For people already dealing with swelling, keeping daily sodium intake between 1,375 and 1,800 milligrams can make a meaningful difference. That’s well below the 3,400 milligrams the average American eats daily.
Most excess sodium doesn’t come from the salt shaker. It hides in processed foods, restaurant meals, canned soups, deli meats, bread, and condiments. Reading nutrition 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 excrete sodium more efficiently.
Staying Hydrated (but Not Overdoing It)
It sounds counterintuitive, but drinking enough water actually helps reduce swelling. When you’re mildly dehydrated, your body compensates by retaining more fluid. Staying well-hydrated keeps your kidneys flushing sodium and waste products efficiently. There’s no need to force excessive amounts of water, though. Drinking far too much can dilute sodium levels in your blood, a condition that causes its own type of cellular swelling. For most people, drinking when thirsty and aiming for pale yellow urine is a reliable guide.
One thing worth knowing: common over-the-counter pain relievers like ibuprofen and naproxen can cause your kidneys to retain water. If you’re taking these regularly and noticing puffiness in your hands or feet, that connection is worth exploring.
Compression Garments
Compression stockings and gloves apply steady, graduated pressure that keeps fluid from settling in your tissues. They come in different pressure levels measured in millimeters of mercury (mmHg), and choosing the right level matters.
- 15 to 20 mmHg (mild): Good for prevention and very mild swelling. Often used during air travel or long periods of sitting.
- 20 to 30 mmHg (moderate): The most commonly prescribed level for everyday use. Works well for mild to moderate swelling in both hands and feet, and balances effectiveness with comfort.
- 30 to 40 mmHg (firm): Used for more persistent lower-leg swelling, especially when moderate compression isn’t enough. Legs generally need firmer compression than arms because gravity creates a heavier load on the lower body.
Put compression garments on first thing in the morning before swelling has a chance to build up during the day. If you’ve never worn them before, starting at a lower pressure level and building tolerance is easier than jumping straight to firm compression.
Swelling During Pregnancy
Some degree of hand and foot swelling is normal during pregnancy, especially in the third trimester. Supportive stockings, elevating your feet when seated, and rotating your ankles while sitting all help. Standing or walking in a pool is particularly effective because the water pressure gently compresses your legs. Avoid clothing with tight bands around your ankles or calves, which can restrict blood flow and make swelling worse.
Don’t reduce your water intake to try to combat the puffiness. Your body needs more fluid during pregnancy, not less. However, sudden or severe swelling in your face and hands, particularly when paired with headaches, vision changes, or upper abdominal pain, can be a sign of preeclampsia and needs prompt medical evaluation.
When Swelling Points to Something Deeper
Most hand and foot swelling is harmless, but certain patterns deserve attention. Swelling that affects only one leg, especially if the skin is warm, red, or painful, could indicate a blood clot. This is a medical emergency.
Swelling in both legs that develops gradually and doesn’t go away with elevation may be tied to heart, kidney, or liver problems. In heart failure, for example, the heart can’t pump blood forward efficiently, so blood backs up in the veins and fluid leaks into tissues, particularly in the ankles, lower legs, and abdomen. Kidney disease reduces the body’s ability to remove excess fluid and sodium, while liver disease lowers protein levels in the blood, weakening the pull that keeps fluid inside your vessels.
Watch for these patterns that suggest the swelling isn’t just lifestyle-related: rapid unexplained weight gain (several pounds in a few days), swelling that leaves a visible dent when you press on it and doesn’t bounce back quickly, shortness of breath, swollen neck veins, or swelling that steadily worsens over weeks despite home treatment.
Medical Treatment for Persistent Swelling
When home measures aren’t enough, doctors typically prescribe diuretics, medications that help your kidneys release more sodium and water into your urine. These work well for swelling caused by heart failure, kidney problems, or liver disease, though the specific type prescribed depends on the underlying cause. Diuretics reduce the total volume of fluid in your body, which lowers the pressure that forces fluid into your tissues.
For conditions like heart failure or liver disease, treating the root cause is just as important as managing the swelling itself. Diuretics address the symptom, but controlling blood pressure, managing heart function, or treating kidney disease prevents the fluid from accumulating again. If you’re prescribed diuretics, your doctor will likely monitor your blood work periodically because these medications can shift your electrolyte levels.
