Postpartum swelling typically resolves on its own within about a week as your body sheds the extra fluid it accumulated during pregnancy. But there are several things you can do to speed that process along and stay comfortable while it happens. The swelling shows up most often in the feet, ankles, legs, and hands, and it’s driven by a combination of hormonal shifts, expanded blood volume, and the fluid your body retained over nine months of pregnancy.
Why Your Body Is Still Swollen After Delivery
During pregnancy, your plasma blood volume increases significantly, your heart pumps harder, and your capillaries become more permeable, meaning fluid passes through vessel walls more easily. At the same time, the protein concentration in your blood drops, which normally helps pull fluid back into your blood vessels. With less of that pulling force and more fluid in your system, the excess pools in your tissues.
After delivery, your body doesn’t flip a switch. It takes days for your kidneys to process and excrete all that extra fluid. If you had a C-section or received IV fluids during labor, the swelling can be even more pronounced. Hospitals typically administer a 500 ml fluid bolus before an epidural, followed by a continuous drip, and research shows that women who receive IV fluids during labor experience higher levels of tissue swelling afterward. Your body simply has more fluid to work through.
Stay Hydrated (Yes, Really)
It sounds counterintuitive, but drinking more water helps your body release retained fluid. When you’re dehydrated, your kidneys hold onto water and sodium. Staying well hydrated signals your body that it’s safe to let go of the excess. European food safety guidelines recommend about 3,300 ml of total fluid per day for breastfeeding women, while other expert recommendations go as high as 3,800 ml during lactation. That’s roughly 11 to 13 cups a day.
If you’re breastfeeding, adequate hydration is especially important because lactation itself draws on your body’s water supply. Your kidneys actually adapt during breastfeeding, increasing filtration rate and reabsorbing more salt and water to protect milk production. Keeping a water bottle nearby and sipping throughout the day is one of the simplest things you can do for both swelling and milk supply.
Reduce Sodium and Add Potassium
Sodium holds onto fluid in your tissues. The more you consume, the more water your body retains. Most health professionals recommend keeping sodium under 2,300 mg per day, but in the postpartum period, actively cutting back can make a noticeable difference in how quickly swelling goes down.
The biggest culprits are processed and packaged foods: frozen dinners, chips, canned vegetables, packaged rice and noodle mixes, condiments, and even cheese and breakfast cereals. Swapping these for whole foods, even temporarily, can help. At the same time, eating more potassium-rich foods helps your kidneys excrete sodium through urine. Bananas, sweet potatoes, avocados, spinach, and yogurt are all good options that are easy to eat one-handed while holding a newborn.
Elevate Your Feet and Keep Moving
Gravity works against you when you’re sitting or standing for long stretches. Propping your feet up above heart level, even for 15 to 20 minutes a few times a day, lets fluid drain back toward your core where your kidneys can process it. When you elevate, keep a slight bend in your knees with support underneath them rather than locking your legs straight.
Gentle movement is equally important. NHS physiotherapists recommend a simple ankle pump exercise: while lying down or sitting with your legs extended, flex your feet toward you and then point them away, then circle your ankles in both directions. Aim for about 10 repetitions every hour you’re awake. This rhythmic contraction of your calf muscles acts like a pump for your circulatory and lymphatic systems, pushing fluid up and out of your lower legs. Avoid crossing your legs or ankles, and try not to stand still in one position for extended periods.
Short, gentle walks around the house count too. You don’t need a formal exercise routine. Just getting upright and moving periodically keeps circulation active and helps your body process fluid faster.
Compression Socks and Postpartum Massage
Compression stockings apply graduated pressure to your legs, squeezing fluid upward and preventing it from pooling in your feet and ankles. For mild postpartum edema, a compression level of 15 to 20 mmHg is often sufficient. If your swelling is more significant, stockings in the 20 to 30 mmHg range provide stronger relief. These are available over the counter at most pharmacies. Put them on first thing in the morning before swelling accumulates for the day.
Postpartum massage, particularly techniques that focus on lymphatic drainage, can also help your body process excess fluid. During pregnancy, body fluids increase by roughly 50%, and targeted massage improves circulation enough to help restore that balance. Postpartum massage is generally done within the first 12 weeks after birth. If you had a C-section, preeclampsia, high blood pressure, or a recent surgical complication, check with your provider before booking a session, since increased circulation isn’t always appropriate in those situations.
Swelling After a C-Section
C-section recovery often comes with more swelling than vaginal delivery for a few reasons. You received more IV fluids during surgery. You’re less mobile in the first couple of days, which means fluid has more opportunity to pool. And the surgical site itself triggers a local inflammatory response that adds to overall tissue swelling.
The same strategies apply, but early movement matters even more. Start with ankle pumps while you’re still in bed, and begin short walks as soon as your medical team gives the go-ahead. Compression stockings are particularly useful after a C-section because they compensate for the reduced movement during your initial recovery days.
When Swelling Is a Warning Sign
Most postpartum swelling is normal, but certain patterns signal something more serious. Postpartum preeclampsia can develop in the days or weeks after delivery, even if your pregnancy was uncomplicated. The key symptoms to watch for are a blood pressure reading of 140/90 or higher, severe headaches that don’t respond to typical pain relief, vision changes like blurriness or light sensitivity, pain in your upper belly under the right side of your ribs, nausea and vomiting, shortness of breath, or a noticeable drop in how often you’re urinating.
Swelling that is dramatically worse in one leg compared to the other raises concern for a blood clot. Deep vein thrombosis presents with one-sided leg swelling in about 88% of postpartum cases, along with leg pain or discomfort in 95% of cases. Redness or warmth in the affected leg and difficulty walking are additional red flags. The postpartum period carries an elevated risk for blood clots, so asymmetric swelling deserves prompt evaluation.
If your swelling hasn’t improved at all after a week, or if it’s getting worse rather than better, that’s also worth a conversation with your provider. Normal postpartum edema follows a clear downward trajectory. Swelling that stalls or worsens suggests something beyond the routine fluid shift.
