Lymphatic drainage during pregnancy

Manual lymphatic drainage in an uncomplicated pregnancy is light, side-lying work on the legs, arms, face and neck. What one small study measured.

By The Renu lymphatic and massage team · 6 min read

Manual lymphatic drainage can be done in an uncomplicated pregnancy, and the one published study of it found that an hour of drainage reversed the normal daytime gain in leg volume (a loss of 44 grams versus a gain of 40 grams on days without treatment). It is light, rhythmic skin-stretching on the legs, arms, face and neck, done side-lying or semi-reclined, never deep work on the abdomen. It eases the ordinary fluid of pregnancy; it does not treat the sudden or one-sided swelling that signals pre-eclampsia or a clot, which needs a doctor the same day.

Why pregnancy makes you hold fluid

Your body holds more water than usual when you are pregnant. The NHS explains the rest in one line: the pressure of the growing womb affects the blood flow in your legs, and the extra fluid tends to settle in the lowest places, which is why ankles, feet and fingers puff up and why it is worse later in the day and in warm weather. Gradual swelling of this kind is not usually harmful to you or the baby, but it is uncomfortable, and it is the fluid that lymphatic drainage is designed to move.

Lymph has no pump of its own. It relies on muscle movement, breathing and the gentle stretch of the skin to push fluid through the vessels toward the lymph nodes and back into the bloodstream. Manual lymphatic drainage reproduces that stretch by hand. If you want the mechanism in full, our Learning Centre page on lymphatic drainage covers it.

What the research measured

The evidence base is small and we want to be exact about it.

A 2013 study followed 15 pregnant women (30 legs) between the fifth and eighth month of pregnancy. Women with high-risk pregnancies were excluded. Each had her leg volume measured by water displacement at about 7 to 8 am and again at 2 to 3 pm, on a day with no treatment and on a day with one hour of manual lymph drainage in the Godoy technique. On the control days the legs gained a mean of 40 grams between morning and afternoon. On the treatment days they lost a mean of 44.4 grams. The difference was statistically significant (P = 0.04). The authors note theirs was the only published study of the question, and that remains the honest summary: one small study, one day, encouraging direction.

The Cochrane review of treatments for leg swelling and varicose veins in pregnancy (seven trials, 326 women) adds useful context from other approaches:

What was tested	What the trial found
Foot massage versus routine care (80 women)	No difference in lower-leg circumference
Water immersion for 20 minutes in a pool (32 women)	Reduced leg volume
Compression stockings versus rest	No significant difference in lower-leg volume
Reflexology (55 women)	Fewer oedema symptoms
Rutosides (69 women)	Fewer varicose vein symptoms, moderate quality evidence

Cochrane’s conclusion is that there is not enough evidence on treatments for varicose veins and leg oedema in pregnancy. Note that the foot massage trial was ordinary massage of the feet, not lymphatic drainage of the whole leg, and it measured circumference rather than volume. Those are different things, which is why we do not claim the Cochrane result either supports or contradicts the drainage study.

What a pregnancy lymphatic session involves

The strokes are the same ones used for post-surgical and lymphedema clients; the set-up changes.

Position. On your side with a pillow at your back and another between your knees, or semi-reclined with the upper body raised. This follows the safety guidance in the 2021 review of pregnancy massage trials, which recommends lateral or sitting positions rather than lying flat.
Order. Every session opens at the neck and collarbones, where the lymphatic system drains into the veins, then works the armpits and groin nodes before moving to the limbs. Clearing the destination first is what lets the leg fluid move.
Regions. Legs from the groin to the toes, arms, hands, face and neck. Puffy fingers and a tight ring respond well to arm and hand work.
The abdomen. No deep abdominal work in pregnancy. The review’s guidance is that the pregnant abdomen should not be massaged, and lymphatic work there is confined to the lightest skin contact over the sides of the trunk or left out altogether.
Pressure. Light enough that it would not move a coin resting on the skin. If it feels like a massage, it is not lymphatic drainage. Our answer on why the pressure is so light explains what the vessels need.
Legs. No deep muscle work on the calves or thighs. The review singles out the risk of dislodging a clot as the reason, and lymphatic strokes are superficial by design.

At Renu this is delivered by our lymphatic-trained Registered Massage Therapists: Meeghan Mackenzie is a Certified Lymphedema Therapist, and Sasha Bernard, Monica Von Gaza and Leah Buschau each hold lymphatic drainage training alongside their RMT credentials. A classic lymphatic drainage session is 30 minutes for $95, 45 minutes for $105 or 60 minutes for $130, and the massage and lymphatic combination (60 minutes for $130, 90 minutes for $165) pairs it with the prenatal massage many clients already have booked.

Lymphatic drainage or prenatal massage: which one

They do different jobs. Prenatal massage uses moderate pressure on muscle to ease the back, hips and legs, and the trials behind it measured pain, anxiety and mood. Lymphatic drainage uses very light pressure on skin to move fluid, and the one trial behind it measured leg volume. If your main complaint is aching, book the massage. If it is tightness, puffiness and shoes that no longer fit by evening, book the drainage or the combination. If you are unsure, say so when you book and the therapist will split the time.

The honest ceiling

Lymphatic drainage eases the fluid of a normal pregnancy for hours to a day or two at a time. It does not change the reasons the fluid is there, so it comes back, and it does nothing for swelling caused by a problem with blood pressure or a clot. The 2013 study excluded high-risk pregnancies, so its finding applies only to uncomplicated ones. If your pregnancy is being followed for a complication, we ask for your obstetrician’s or midwife’s input before we treat.

When to see a doctor or midwife instead

Lymphatic work is paused and medical care is sought the same day if you notice:

a sudden increase in swelling of the face, hands or feet, especially with a severe headache, blurred vision or flashing lights, pain just below the ribs, persistent heartburn, nausea or vomiting, or simply feeling unwell. The NHS lists these as the signs of pre-eclampsia, which can lead to serious complications if it is not monitored and treated.
swelling or throbbing pain in one leg rather than both, usually the calf or thigh, with red, blue or darkened skin around the painful area. Pregnancy and the six weeks after birth carry a higher risk of deep vein thrombosis, and a clot can travel to the lungs. If a painful leg comes with chest pain or shortness of breath, call 911.

Symmetrical, gradual swelling of both ankles that is worse at the end of the day is the kind lymphatic drainage is for. One leg, a sudden change, or swelling that arrives with a headache is not. Our page on swollen feet and ankles in pregnancy goes through the self-care that sits alongside treatment.

Questions people ask

Is lymphatic drainage safe in the first trimester?

The pregnancy study we rely on enrolled women in the fifth to eighth month, and the massage trials in the 2021 review all started at twelve weeks or later, so there is no trial evidence either way for the first trimester. We do not claim it is unsafe; we say it is unstudied, and we ask you to check with your care provider before booking in the first twelve weeks.

Will lymphatic drainage make me need the toilet more?

Often, yes. Moving tissue fluid back into circulation gives the kidneys more to process, and clients commonly notice they pass more urine in the hours after a session. In pregnancy you are already visiting the bathroom often, so plan the session for a time when that is not a nuisance.

Can I have lymphatic drainage and a prenatal massage in the same visit?

Yes. The massage and lymphatic combination is 60 minutes for $130 or 90 minutes for $165, and a prenatal massage on its own is $120 for 60 minutes or $157 for 90. The lymphatic portion is done first or last depending on what you most want from the session.

Does lymphatic drainage reduce swelling permanently in pregnancy?

No. The study measured leg volume over a single day, and the cause of the fluid (more blood volume and the uterus slowing venous return) is still there the next morning. Expect a lighter, less tight feeling that lasts hours to a day or two, and repeat sessions if that relief is worth it to you.
