Birth Planning for Future Health
There comes a
point in your pregnancy when you realise that this baby actually has to come
out. You might laugh thinking back, but often we are so excited to be pregnant
that we haven’t thought further than being pregnant. When you type “Birth Plan”
into your search engine, immediately there are 13 300 results. Each of these
has excellent advice on preferences and options that you should think about in
order to make a positive birth experience. Some are very practical in the sense
of what to pack, who should be allowed into the labour ward and when should you
have an enema so not to poop on the table; but what if some of these decisions
could impact the long term health of your unborn baby. Suddenly, how scary that
we not only have to plan for beyond the pregnancy, but the responsibility of
decisions made at birth could have far reaching impact.
Recent
terminology that is starting to filter into these plans is the Microbiome. "Two
amazing events happen during childbirth. There's the obvious main event which
is the emergence of a new human into the world. But then there's the non-human
event that is taking place simultaneously, a crucial event that is not visible
to the naked eye, an event that could determine the lifelong health of the
baby. This is the seeding of the baby's microbiome.” (1). The
human microbiome consists of trillions of microbes – bacteria and viruses—the
balance of which largely determines our health and well-being throughout life.
The largest microbiomes in women are located in the mouth the gut, the uterus,
the vagina, and the skin. Breastmilk also provides a vital microbiome for the
infant.(2). The microbiome is normally transferred from mother to
baby via the placenta during pregnancy; the vaginal canal during birth; and the
mother’s skin, breastmilk, and lips in the hours, days and weeks after birth.
The microbes and their genetic material play an essential role in the child’s
health, development, and metabolism. Disruption in the transfer of the
microbiome in the perinatal period due to changes in the way pregnancy
and birth are managed in the hospital have led to the increase in many
diseases, such as allergies, asthma, diabetes, gastrointestinal diseases,
obesity, autoimmune disorders, and some mental disorders. Until the past few
years, the connection between the altered microbiome and poor health was
virtually unknown. With newer technologies that allow for the study of microbes
that were previously impossible to study, these connections are beginning to be
discovered. (3).
Let’s go back to looking at just a few things on our
birth plans while keeping the maintenance of the microbiome as our heading:
Mode of delivery – Unfortunately cesarean delivery (CD)
is no longer reserved for medical reasons, but the massive increase in elective
CD sitting in the 80% in some private clinics, has put this on the list of birth
planning. During vaginal delivery, the contact with the vaginal flora is an
important start to the infants colonization, this is absent in CD. Studies are
showing that babies born vaginally are colonised with lactobacillus, whereas cesarean delivery babies were colonized by a
mixture of potentially pathogenic bacteria typically found on the skin and in
hospitals, such as Staphylococcus
and Acinetobacter.
The effect of this appears to be most robust in the area of immune mediated
diseases. CD has been associated with a significant increased rate of asthma
and allergic rhinitis.(4).

Antibiotics, widely used for the mother during pregnancy
and birth and for the infant afterwards, destroy helpful microbes. Even though
this is not usually the choice of the mother, as prescribed, but by just discussing
risk vs reward with prescribing physician can go a long way to avoiding
unnecessary usage.
Breastfeeding /
Formula feeding and the consistent use of the formula top up. Infant formula
deprives the baby of the rich breastmilk microbiome, and impairs the normal
development of the newborn’s immune system and maturation of the baby’s gut
microbiome. (5). Exclusive breastfeeding has a protective role of
breast-feeding against the development of diarrhoea and necrotizing
enterocolitis in the newborn and allergic and autoimmune diseases in childhood,
including coeliac disease type I diabetes and atopic dermatitis. Later in life,
breast-feeding has been associated to a reduced risk of inflammatory bowel
diseases, cardiovascular diseases, obesity, and type-2 diabetes. (7).
Many woman are
exclusively breastfeeding, oh ja, except for that top up or 2 that baby received in
the hospital, or some choose for various reasons to mix feed. Breastfed and
formula fed infants have different gut flora. The science bit: Breastfed babies have a lower gut pH
(acidic environment) of approximately 5.1-5.4 throughout the first six weeks
that is dominated by bifidobacteria with reduced pathogenic (disease-causing) microbes
such as E coli, bacteroides, clostridia, and streptococci. Babies fed
formula have a high gut pH of approximately 5.9-7.3 with a variety of putrefactive
bacterial species. When formula supplements are given to breastfed babies
during the first seven days of life, the production of a strongly acidic
environment is delayed and its full potential may never be reached. Breastfed
infants who receive supplements, develop gut flora and behavior like
formula-fed infants, the dominance of bifidobacteria during exclusive breastfeeding
decreases when infant formula is added to the diet. (6). Exclusive and partial
formula-feeding have been shown to alter the gut microbiome toward adult
patterns, increase proinflammatory bacteria, and increase gut permeability, and result in
lower concentrations of fecal short-chain fatty acids compared with
exclusive breastfeeding. (8).
Now you are
thinking so what? What all this leads to is that just one bottle can have a
long-term consequence on immune health as well as reduced protection against
overweight and obesity.
These are just a
few examples of how the microbiome can be altered at birth, and as research in this
field expands, there will be an impact on our birth plans and how we are
treated in maternity care facilities. You are the advocate for your baby, when
you are putting together your birth plan, add microbiome to the google search,
and insist that your health care team THINK GUT.
