Breech Presentation

What is Breech Presentation?

Breech presentation means the fetus lies lengthwise with the buttocks or legs, rather than the head, entering the mother's pelvis first.^[1] It is a position of the baby, not an illness, and it is managed by an obstetric provider.

Common symptoms

Breech presentation usually causes no symptoms you can feel. It is typically found when a provider examines the abdomen and is confirmed with ultrasound.^[1]

There are three types. In a frank breech, the hips are bent and the legs extend up toward the face. In a complete breech, the baby sits with hips and knees both bent. In an incomplete breech, one or both hips are extended, including footling breech, where one or both feet come first.^[1]

Causes and risk factors

Breech presentation is common earlier in pregnancy and less common at the end. Nearly one fourth of babies are breech at 28 weeks, but only about 3 to 4 percent are at term.^[2] Most babies turn head down on their own as pregnancy advances.

Factors that can make a breech position more likely include a baby born early, more than one baby, too much or too little amniotic fluid, a low-lying placenta, and an unusually shaped uterus or fibroids. Often no cause is found.^[1]

How it is diagnosed and treated conventionally

Providers check the baby's position by feeling the abdomen and confirm it with ultrasound.^[1]

External cephalic version (ECV) is a procedure in which a provider turns the baby from outside the abdomen. It may be offered after 37 weeks, and its overall success rate approaches 60 percent.^[2] A Cochrane review of eight trials found that attempting ECV at term reduced both breech presentation at birth and cesarean section, although the trials were limited and the data on complications were not sufficient.^[3]

Most breech babies are delivered by cesarean section.^[2] A meta-analysis of observational studies found higher rates of perinatal death and birth trauma with planned vaginal breech birth, and slightly higher severe maternal complications with planned cesarean.^[4] National guidelines differ on ECV and on vaginal breech birth, so counseling from your own provider matters.^{[5, 6]}

Why Breech Presentation calls for a whole-person approach

Why a baby stays breech depends on timing, the shape and space of the uterus, and the baby itself, and it is not always possible to know. The decisions that follow involve safety, preferences and information, and they belong with your obstetric team.

Supportive care can add attention to comfort and well-being during these decisions. It does not change the medical plan.

Timing in pregnancy

Because most babies turn without help, a breech position at 28 weeks often changes by term.^[2] This is also why research on turning techniques needs control groups, since many babies turn on their own.

Space and shape in the uterus

The uterus, placenta and amniotic fluid affect how freely the baby can move.^[1] Your provider looks for these factors on ultrasound, which is another reason evaluation comes first.

Maternal position

Positioning techniques with the pelvis raised, such as the knee-chest position, have been studied. A Cochrane review of six trials with 417 women found insufficient evidence from well-controlled trials to support postural management.^[7]

Informed choice and stress

Guidelines differ, and a review has argued that women should be given balanced counseling on the risks of both vaginal breech birth and cesarean section.^[6] Uncertainty about birth plans can be stressful, and supportive conversations are part of care.

Acupuncture as supportive care in Breech Presentation

What the research shows

The research on acupuncture-type treatment for breech presentation is mixed, and the evidence is limited. Most of it is moxibustion, in which the herb mugwort is burned near an acupuncture point on the little toe called Bladder 67. It is sometimes combined with needling.^[8]

The 2023 Cochrane review included 13 trials with 2,181 women. It found moderate-certainty evidence that moxibustion plus usual care probably lowers the chance of a non-head-down position at birth. It also found it probably makes little or no difference to cesarean rates, and that the effect on the need for ECV was very uncertain.^[8] A 2021 meta-analysis of 16 trials with 2,555 women found more head-down babies at birth with moxibustion, but the effect of needling alone was inconsistent.^[9]

Individual trials disagree. In Spain, a trial of 406 women found that 58 percent of babies were head down at birth with moxibustion at the true point, compared with 43 percent with moxibustion at a non-specific point and 45 percent with usual care alone.^[10] An Italian trial of 240 women found acupuncture plus moxibustion gave more head-down births than observation.^[11]

Several other trials found no benefit. A French placebo-controlled trial of 328 women found no significant difference at 37 weeks,^[12] and a sham-controlled trial of 259 women found that needling with fire needling at the same point did not increase turning.^[13] A Danish trial of 200 women^[14] and a Swiss trial of 212 women^[15] also found no effect.

How acupuncture may work

A review of moxibustion describes proposed mechanisms but notes that research on its effects on breech presentation is sparse, and that efficacy, safety and the best technique need more study.^[16] These are hypotheses, not settled facts.

What treatment involves

Acupuncture uses fine, sterile, single-use needles, usually left in place for about 20 to 40 minutes. In trials, treatment began in the third trimester and was repeated over several sessions, or daily for two weeks in one moxibustion trial.^{[12, 15]} Timing, and any decision about turning the baby, are made with your obstetric provider.

In prospective studies, about 9 in 100 patients had a minor reaction such as bleeding, soreness or a flare at the needle site, and serious events occurred in about 1 in 10,000 patients.^[17] Safety data for moxibustion are limited. One small monitoring study found no changes in fetal or maternal well-being.^[18] The Cochrane review, however, found adverse events inadequately reported, and one study reported nausea, unpleasant odor, abdominal pain and uterine contractions in some women.^[8]

Tell the practitioner first if you have vaginal bleeding, a low-lying placenta, a history of preterm labor or a bleeding disorder, or take blood thinners.

Ayurvedic medicine as supportive care in Breech Presentation

The Ayurvedic view

Ayurveda has detailed traditional guidance on pregnancy care. In this framework, the downward movement of the baby at birth is attributed to a form of Vata called Apana Vata. This is a traditional explanation, not a biomedical finding.

Therapies that may be used

Care in pregnancy is limited to gentle measures, such as regular nourishing meals, rest and stress-reducing routines, chosen with your obstetric provider's knowledge. Panchakarma procedures are not appropriate during pregnancy. Herbal preparations are generally avoided unless your obstetric provider agrees. Product quality is a concern, since about one fifth of Ayurvedic products bought online contained detectable lead, mercury or arsenic.^[19]

What the research shows

We found no clinical studies of Ayurvedic treatment for breech presentation. The traditional-medicine trials that do exist test moxibustion and acupuncture, not Ayurveda.^{[8, 9]} Nothing in the published literature we reviewed shows that Ayurvedic therapy turns a breech baby or changes the way the baby is delivered.

Herbal medicine as supportive care in Breech Presentation

Herbs and formulas that have been studied

Moxibustion uses the herb mugwort (Artemisia) burned near the skin, and it is studied as a heat therapy at an acupuncture point.^[8] We found no studies of herbs taken by mouth for breech presentation.

What the research shows

There is no clinical evidence that herbal medicine changes fetal position. The only evidence in this area concerns moxibustion, described under acupuncture above.

Safety and herb-drug interactions

Herbs taken by mouth are not appropriate for a pregnancy without your obstetric provider's approval, and some are avoided in pregnancy. Herbs can interact with medicines, for example by raising bleeding risk with blood thinners.^[20] Product quality is also a concern. In one study, about one fifth of Ayurvedic products bought online contained detectable lead, mercury or arsenic.^[19]

Transdermal medication therapy, an herbal preparation applied to the skin, is also offered, but we found no studies of it for breech presentation.

Translating traditional medicine into modern biological language

The comparisons here are interpretation, not equivalence. Chinese medicine uses Bladder 67 on the little toe because of its traditional link to the uterus and the bladder channel, and the heat of moxibustion is traditionally said to move qi. Researchers have proposed that stimulating this point may influence fetal movement, but the biological mechanism is unproven.^[16]

Ayurveda attributes the baby's descent to Apana Vata. No study has shown that a dosha corresponds to a specific biological process, and no trial links Ayurvedic ideas to fetal position.

How this care fits with your medical care

Supportive care works alongside your obstetrician or midwife, and it never replaces their guidance. For a condition like this, we ask that you are under a physician's care for it and that your treating team knows you are receiving complementary care.

Decisions about ECV, how to give birth and the timing of any treatment belong with your obstetric provider. Do not delay or decline recommended monitoring or ECV in order to try other methods. Please bring your due date, your ultrasound results, your provider's plan and a list of all medicines and supplements.

When to seek urgent medical care

Contact your obstetric provider right away, or go to the hospital, if you have any of the following in pregnancy.

• Vaginal bleeding
• Leaking or a gush of fluid
• Regular contractions or labor pains before 37 weeks
• A noticeable drop in your baby's movements
• Severe headache, vision changes or sudden swelling
• Constant severe abdominal pain

If you think you are in labor with a breech baby, or in any emergency, call 911 or go to the nearest emergency department.
