The final touches happen in the last weeks before birth

Posted by Dr Sandy on in pregnancy | 210 Views | Leave a response

putting the finishing touches to babyYou feel like a beached whale. You’re HOT and have lots of aches and pains. You’ve had enough – you’re ready to give birth, to get the show on the road and begin being a mother.

But it is not about whether you’re ready.

The million dollar question………… is your baby ready to be born ?

Probably not.

Coming early is trending

Researchers from the Mayo Clinic report on a disturbing trend……..

10 to 15 % of births happen, before 39 weeks, which is early if you’re “normal” and seriously early if you are a late bloomer.

The reason for these early arrivals.

BECAUSE…..

In the majority of cases, there is no true medical indication for early delivery.

Coming early is RISKY

Multiple studies have shown, pre-term births i.e. early arrival, even marginally early arrivals, are associated with COMPLICATIONS. The most conspicuous difficulties, arise in the breathing department and/or feeding department.

This makes sense, because these two systems are being worked on, right until the moment of birth.

Taking the first breath

Of air. This is huge…..

Up until the big moment, Mom’s lungs have ensured the blood pumping around is fully oxygenated. The lungs in utero are full, not of air, but liquid – necessary for development, but not suited for breathing air.

To catch their first breath, the lungs need this fluid to be drained. Plus the lungs need to be coated, with a special surfactant secretion, that stabilizes them sufficiently, so they can handle the air pressure.

In addition to readying the breathing equipment, the plumbing system needs a little re-routing. As the placenta goes off line, the lung circulatory system needs to kick in.

Disconnecting the feeding tube

The disconnection of the placenta, does more than just discontinue the air supply, it also cuts the food supply too. The moment the cord is severed – glucose levels plummet.

The liver needs to make a plan and begin the process of gluconeogenesis i.e. making it’s own glucose, in order to keep the body fuelled up. And to make matters worse, the demand for fuel rockets, because being born is hard work and the outside world, is “FREEZING” !

This is serious…………

Being born involves metabolic shifts. Insulin levels fall and glycogen emerges as the stand-by energy source. To keep warm (thermogenesis) and keep going, the baby needs to tap it’s rather limited reserve.

Reserves that are only put in place, in the period just before birth, since there is no point in storing fuel for a rainy day. The placenta guarantees the absence of rainy days.

The big transition

This BIG transition is driven by hormones. The hormone that leads the pack is cortisol – the stress hormone, along with the catecholamines. These hormones, only arrive on the scene, late in the game. Mother Nature waits till the end, to add the finishing touches, these finishing touches ensure the baby makes the transition from the warm cosy womb, to the big wide world, smoothly.

So, when a baby comes early, even just a little, the package is not a hundred percent complete and there can be complications.

Don’t get inpatient or get talked into speeding things up. Trust Mother Nature – her timing is PERFECT. The moment the water bursts………she is announcing, she is done, your baby is now ready for delivery.

we forget it’s doing a job.

And midlife is when these conversations start showing up —
cholesterol, statins, shifting risk.

If this is on your radar…
there’s a free Navigating the Middle Years bundle open right now.

50+ resources on midlife health, hormones and what’s actually going on.

⏳ Closes tomorrow

Hop inside, you'll find the link in bio.

Everyone fears sugar spikes… but almost no one realises sugar crashes shake your blood vessels too.
Inside your bloodstream, stability matters more than perfection.

Agent Vaso is the quiet operator keeping your flow steady — until things drop faster than he can respond.

I’ve spent a long time trying to figure out how to explain what I actually do in a way that feels honest — not salesy, not dramatic, and not simplified to the point of being wrong.

What I finally landed on is something I call Unlocking Better Body Chemistry.

It’s not a program or a protocol.
It’s a way of looking at health problems — especially metabolic ones — that focuses on why things aren’t responding, instead of just chasing symptoms.

Most people I talk to are already doing a lot of “right” things.
They’re just doing them without a clear understanding of how their own body is functioning.

This framework is how I make sense of bloodwork, symptoms, and context together — and how I help people stop guessing about what actually matters.

I’ve put it all into a page so it’s clear, grounded, and easy to read.

If you’re curious, you can read it here. (link in first comment)

Your body isn’t misbehaving.
Its clocks are out of sync.

Every cell runs a molecular timekeeper — CLOCK, BMAL, PER and CRY — driving your energy, appetite, sleep pressure and mood.

When those clocks drift, everything feels “off,” and people blame willpower instead of timing.
