5 Expert-Backed Tips for Managing Swollen Ankles in Late Pregnancy

Carrying a baby into the third trimester often brings a heavy, achy feeling that starts somewhere around your calves and settles in your feet. Nearly three out of four pregnant people deal with some degree of edema—swelling from extra fluid and the pressure of a growing uterus. While puffy ankles are rarely a cause for alarm, they can be deeply uncomfortable. Here are five expert-backed strategies to help you find relief without veering into unsafe territory.

1. Position matters: Elevate and shift regularly

Gravity works against you when you’re on your feet all day. Fluid naturally pools in the lowest points of your body, and by late pregnancy, those low points are your ankles. The simplest fix is also one of the most effective: get your feet up. Aim to elevate your legs above heart level for 15 to 20 minutes, two to three times a day. Propping your feet on a stack of pillows while you lie on the couch works fine—no special equipment needed. Also avoid standing or sitting for long stretches. If your job involves a desk, set a timer to stand and walk a few steps every hour. A gentle stroll (even just around the house) helps your calf muscles pump fluid back toward your heart.

2. Hydrate wisely: Water helps flush out excess fluid

It sounds counterintuitive: you’re retaining water, so why add more? But when your body senses dehydration, it holds onto fluid even tighter. Drinking plenty of water throughout the day tells your system it can let go of the reserve. Aim for 8 to 10 cups (about 2 to 2.5 liters) of fluid daily, mostly from water. Cut back on salty foods and sugary drinks, both of which encourage water retention. If plain water gets boring, add a slice of lemon, cucumber, or a few mint leaves. Limit caffeine and avoid alcohol entirely—both can worsen dehydration and swelling.

3. Wear supportive gear: Compression socks and sensible shoes

Medical-grade compression stockings (20–30 mmHg) can make a noticeable difference, especially if you’ll be upright for hours. They work by gently squeezing the lower leg and preventing fluid from settling. Put them on first thing in the morning (before swelling peaks) and take them off at night.

A quick safety note: If you have high blood pressure or diabetes, check with your prenatal provider before using compression wear.

4. Sleep on your left side

Position matters even when you’re horizontal. Sleeping on your left side takes the weight of the uterus off the inferior vena cava—the large vein that returns blood from your lower body to your heart. With that pressure lifted, blood flows more freely and fluid doesn’t pool as much in your legs. If you wake up on your back, don’t panic; just gently roll to your left side. Placing a pillow between your knees and another under your belly can make side-sleeping more comfortable. This simple shift also helps maintain healthy blood pressure and kidney function, which both influence fluid balance.

5. Gentle movement and lymphatic support

You don’t need a workout plan—just a few minutes of gentle motion each hour. Walking, swimming, or prenatal yoga are all excellent for circulation and lymph drainage. Even ankle circles (sitting or lying down) can move fluid out of your feet. Avoid crossing your legs or ankles when sitting; that position restricts blood flow and can trap fluid in the lower legs. If you’re feeling ambitious, try lying on your back (for no more than 5–10 minutes) against a wall with your legs extended straight up—this is sometimes called “legs up the wall” pose and can offer rapid, temporary relief. Always listen to your body; if a movement hurts or feels strained, stop.

While mild swelling is normal, sudden or very rapid swelling—especially if it affects only one leg or is accompanied by headache, vision changes, or chest pain—warrants an immediate call to your provider. Those symptoms can point to preeclampsia or a blood clot, both of which need urgent attention.
