Swollen Feet During Pregnancy and Postpartum: Why It Happens and What Actually Helps

There are certain things about pregnancy and the postpartum period that nobody really warns you about until you're in the middle of them.

Swollen feet is one of those things.

Not a little puffy. We mean can't-fit-into-any-of-my-shoes, my-ankles-have-disappeared swollen. And for many new mums, the cruelest part is that it can actually get worse in the first days after giving birth, just when you thought your body might finally start returning to you.

You're not imagining it. You're not being dramatic. This is extremely common, and there is genuine relief available — including one that involves sitting quietly for twenty minutes while something warm and restorative works on your behalf. But first, let's talk about what's actually going on.

Why do feet and ankles swell during pregnancy?

Swelling (oedema) during pregnancy comes from a combination of factors that are all completely normal parts of growing a human being:

Your blood volume increases dramatically

Your body produces around 50% more blood and bodily fluids during pregnancy to support your baby's development. This extra fluid can accumulate in the tissues, particularly in the feet, ankles and hands — especially as the day goes on and you've been upright for hours.

Your growing uterus adds pressure

As your uterus expands, it puts increasing pressure on the pelvic veins and the vena cava — the large vein on the right side of your body responsible for returning blood from your legs to your heart. When that flow slows down, fluid pools in your lower legs and feet.

Pregnancy hormones change how your body manages fluid

Progesterone causes blood vessels to relax and widen, which can contribute to fluid leaking into surrounding tissues. Your body is doing this deliberately — it's part of how it accommodates everything pregnancy demands. It's clever. It's also deeply uncomfortable by 6pm.

Swelling is most common in the third trimester, typically worsens as the day progresses, and can be significantly worse in warm weather — which makes Australian summers particularly challenging for pregnant women.

Why can it get worse after birth?

This surprises so many new mums, and understandably so. You've had the baby. Surely the swelling should go? For many women, days three to five postpartum are actually the puffiest of all.

A few things cause this:

IV fluids during labour — if you had a drip (common with epidurals, inductions, or longer labours), your body received a significant volume of additional fluid that needs time to process and eliminate. This can cause marked swelling in those first few days.

The hormonal shift after birth — when oestrogen and progesterone drop rapidly after delivery, your body's fluid regulation temporarily shifts. Your kidneys need time to recalibrate and start releasing all that retained fluid.

Post-caesarean inflammation — if you had a c-section, your body is managing surgical inflammation on top of everything else, which adds to swelling.

The reassuring news: postpartum swelling typically peaks around day 3–5 and then begins to resolve. You'll likely notice increased sweating and more frequent urination in that first week — that's your body doing exactly what it should, eliminating the excess. It's working for you, even when it doesn't feel like it.

When should you actually be concerned?

Mild to moderate swelling in the feet, ankles and hands is normal. But please do contact your midwife, GP or hospital immediately if you notice:

• Sudden or severe swelling, especially in the face or hands
• Swelling alongside a severe headache, visual changes, or upper abdominal pain (these can be signs of pre-eclampsia and need immediate attention)
• Swelling in only one leg, or a leg that appears red, hot or painful (possible DVT)
• Swelling that shows no signs of improving in the postpartum weeks

When in doubt, always check with your healthcare provider. That's what they're there for.

Natural ways to find relief

For normal pregnancy and postpartum oedema, these approaches genuinely make a difference — particularly when you use them together.

Put your feet up — literally

The simplest and most effective thing you can do. Lie down and elevate your feet above heart level for 20–30 minutes. Gravity does the work. Even a pillow under your feet while you sleep can help overnight.

Drink more water (yes, really)

It sounds counterintuitive, but staying well hydrated actually helps your body release retained fluid. When you're dehydrated, your body holds onto water as a protective response. Keeping your fluids up signals to your kidneys that they can let it go.

Move gently and often

Long periods of sitting or standing allow fluid to pool. Short, gentle walks, swimming or even ankle circles while seated help keep blood and fluid circulating. Getting up every hour for even a few minutes makes a real difference.

Sleep on your left side

Sleeping on your left side takes pressure off the vena cava and improves blood flow from your lower body back to your heart — which can meaningfully reduce overnight swelling.

Give yourself a magnesium foot soak

This is where we want to linger for a moment, because it's genuinely lovely and it actually works.

Magnesium is involved in over 300 biochemical processes in the body — including muscle relaxation, circulation support and fluid balance. Many pregnant and postpartum women are low in magnesium, as the demands of pregnancy and recovery draw heavily on your body's reserves.

A warm magnesium (Epsom salt) foot soak offers relief in multiple ways: the warmth gently encourages circulation, magnesium may absorb transdermally through the skin, and honestly? The act of sitting quietly for twenty minutes with your feet submerged in something warm and fragrant is itself restorative in a way that's hard to overstate when you're exhausted and uncomfortable.

REVIVE — the foot soak ritual you deserve

We created REVIVE Magnesium Epsom Salt Foot Soak for exactly this moment — for the tired, swollen-footed, growing-a-human (or just-had-a-baby) version of you who deserves something that feels as good as it works.

A simple evening ritual for swollen feet

Here's how to turn "relief" into something you actually look forward to:

1. Fill a basin with warm (not hot) water — very hot water isn't recommended during pregnancy; comfortably warm is perfect and feels wonderful.
2. Add a generous scoop of REVIVE and let it dissolve. You'll notice the scent immediately.
3. Soak for 20 minutes — put on a podcast or some music, close your eyes, just breathe. This is your time.
4. Pat feet dry and elevate — lie down with feet propped up while the magnesium continues to work.
5. Finish with a gentle foot massage if you can manage it — even five minutes of self-massage stimulates lymphatic drainage and makes a meaningful difference.

Do this daily if you can, especially in the evenings when swelling tends to be at its worst. The cumulative effect is real.

A gentle note on self-care in the fourth trimester

The postpartum period asks so much of you. You're healing, feeding, not sleeping, meeting the enormous and beautiful and relentless demands of a newborn — while living in a body that feels unfamiliar and exhausted and sometimes uncomfortable in ways nobody fully prepared you for.

Swollen feet are a small thing in the grand scheme of everything you're carrying. But the act of sitting down for twenty minutes and doing something just for you — that is not small. It's a reminder that you are not simply a vessel for someone else's needs. You are a person who deserves care and gentleness too. Especially now.

That's what we're here for at Little Seedling. Not just products. Rituals that remind you of that.

Your questions, answered

Is it normal to have more swelling after giving birth than during pregnancy?
Yes — very common, especially in days 3–5 postpartum. IV fluids, hormonal shifts and post-birth inflammation all contribute. Swelling typically resolves within 1–2 weeks as your body eliminates excess fluid.

Is a magnesium foot soak safe during pregnancy?
Yes. A warm (not hot) magnesium Epsom salt foot soak is safe during pregnancy. REVIVE by Little Seedling Essence is formulated to be pregnancy and postpartum safe.

How long should I soak my feet to help with swelling?
15–20 minutes is ideal — this gives the magnesium time to work and the warmth time to support circulation. More than a moment to breathe never hurt anyone either.

When should I see a doctor about swollen feet during pregnancy?
Seek immediate care if swelling is sudden and severe, if it comes with a headache and vision changes (possible pre-eclampsia), or if only one leg is swollen, red or painful (possible DVT).

Does drinking more water actually help with swelling during pregnancy?
Counterintuitively, yes. Staying well-hydrated signals to your kidneys that it's safe to release retained fluid rather than holding onto it.
