A couple of weeks ago, I wrote “The Bed Rest Myth” and promised that a post about preventing preterm labor was in the works. 

Here is that promised post on how to prevent preterm labor naturally covering some important questions ask about this topic including:

Can preterm labor be prevented?

What triggers preterm labor?

How can I slow down preterm labor naturally?

Let’s start!

To recap, I got thinking about preterm labor a little over a month ago. A family member was put on bed rest (at 7 months pregnant) for some worrisome cramping and contracting she was experiencing.

Her situation catapulted preterm labor onto my radar screen with big flashing red lights.

Since then I’ve spent considerable time digging through the available research, hoping to find some clues that might be helpful to women facing preterm labor (and those hoping to prevent it).

The Role of Inflammation

There is much I could say about preterm labor and the rise of preterm births over the last two decades, but that’s not really what this post is about. 

What I would like to discuss in detail is a common denominator linking many of the causes of preterm labor—inflammation in the body.

It is fairly well known that prostaglandins ripen the cervix and can induce labor. Increased inflammation in the body means an increase of prostaglandins in the body.

The more I dug into the scientific literature about preterm labor, the more and more convinced I became that a large portion of women experiencing preterm labor has heightened levels of inflammation in their bodies from a variety of sources.

It became a sort of game. I would discover something that had been shown to increase a woman’s risk of preterm birth and then I would do a search to see whether that particular risk factor also increased inflammation in the body. Over and over I found that it did.

Here are some examples:

Stress, Anxiety & Depression

Stress, anxiety, and depression increase the risk for preterm labor.  And there are links between depression and stress and increased inflammation in the body. As one source explained it simply, “[T]he more depression there is, the more inflammation there is” (Dr. Robert J. Hedaya, “Depression, Inflammation, Immunity, and Infection“).

Infections (uterine, placental, urinary tract, and others throughout the body) increase risk for preterm labor. I like this basic explanation from Parenting.com: 

“During a vaginal bacterial infection, for example, the body releases infection-fighting chemicals known as cytokines, which cause inflammation. This inflammation, in turn, launches the release of prostaglandins, which begin the chemical process that initiates contractions and the dilation of the cervix”. 

A similar inflammatory process takes place in response to all types of infection throughout the body.

Magnesium & Vitamin D Deficiency

Magnesium deficiency and vitamin d deficiency increase the risk for preterm labor.  Research also demonstrates that magnesium and vitamin d both reduce inflammation in the body, while naturally, their deficiency increases inflammation.

Doctors have long been aware of the role of inflammation in preterm labor. In fact, one of the treatments commonly suggested to women experiencing preterm contractions is anti-inflammatory drugs like ibuprofen.

My family member who was put on bed rest had been told to take large quantities of ibuprofen to keep her contractions at bay.

She felt really uncomfortable with the amount she was taking (I was shocked too, especially now knowing the risks associated with ibuprofen consumption during pregnancy… ).

Eventually, she asked if she could take less, and then, to her relief, the doctor gave her the go-ahead to stop taking them altogether.

(And, by way of update, she is no longer on bed rest and her contractions have not produced any cervical dilation. Yay!)

Doctors know that inflammation can produce preterm contractions.

So my question is why are they recommending large quantities of drugs like ibuprofen which evidence suggests can lead to miscarriage and birth defects when there are so many other, much safer ways to reduce inflammation in the body?

Reducing Inflammation

So what can pregnant women (or those hoping to become pregnant) do to safely reduce inflammation levels in their bodies and by extension likely reduce their risk of preterm labor? 

There isn’t a cure-all. But there are simple ways for preventing preterm labor.

And most of them are healthy steps (for anyone) and harmless. I can’t guarantee that doing any of these things will prevent or reduce preterm labor symptoms. 

I can only assume that they would be helpful through the application of logic according to the facts I have uncovered. 

I also don’t recommend implementing any of them without first consulting with your midwife or doctor.   Some women will continue to have preterm labor even when all preventative measures have been taken.  But these things just might help…

Reduce Stress, Anxiety, and Depression

If stress, anxiety, and depression can provoke preterm labor, it would make sense to do everything within our power to reduce stress and anxiety levels in our lives and to seek out natural, psycho-therapeutic, or pharmacological anti-depressive aids. Research shows that it has helped a lot of mothers in preventing preterm labor.

Strengthen the Immune System

A strong immune system will attack infections and eliminate them far more quickly, reducing the amount of time the body has increased levels of inflammation.  Check out “Reduce Stress and Strengthen Your Immune System: 10 Natural Ways to Rejuvenate” for some helpful tips for building up your body’s defenses.

Increase Low Magnesium and Vitamin D Levels

What are the best dietary sources for magnesium? Pumpkin seeds, spinach, and swiss chard are some of the best. And I’m partial to sunlight as the ideal source of vitamin d, but supplements are helpful for those who experience real winters or spend a lot of their time indoors.

Increase Your Pre-pregnancy Fitness Level and Stay Active

While pregnancy isn’t the ideal time to work on losing excess weight or to start a rigorous exercise program, research does indicate that “high body fat is related to high inflammation and high fitness to low inflammation” (Science Daily, “Fitness Reduces Inflammation“). 

The ideal would be for women to get into shape prior to becoming pregnant and continue to stay active during pregnancy (with their care providers’ approval). Research has found that moderate prenatal exercise may “be of value in preventing preterm labor.”

Foods to Help Prevent Preterm Labor

I began learning about anti-inflammatory foods about four years ago when I first learned that raw pineapple had anti-inflammatory properties much like over-the-counter pain relievers (such as ibuprofen). 

I dug deeper into anti-inflammatory foods earlier this year searching for ways to reduce my daily aches and pains naturally. 

Rather than taking vast quantities of ibuprofen, you may want to try consuming larger quantities of anti-inflammatory foods such as olive oil, fish oil (and other omega-3?s), turmeric, sweet potatoes, blueberries (and other berries), papaya, pineapple, broccoli, cauliflower, cherries, garlic, ginger, almonds, apples, cinnamon, dark chocolate, rosemary, chili peppers, meats from grass-fed animals (if you’re a meat-eater), and.

You’ll also want to reduce your intake of foods that increase inflammation such as refined sugars and grains, polyunsaturated vegetable oils (such as safflower, soy, sunflower, corn, and cottonseed oil), processed meats, alcohol, MSG, aspartame, and any foods you may be allergic to.

Some people also go for supplements to prevent preterm labor but my hope is that more and more care providers will begin recommending more natural ways to reduce inflammation to all their clients, particularly those who experience preterm contractions. 

But, having said that, I also want to make it clear that preterm labor should be taken very seriously. Applying the above tips for preventing preterm labor is fine but do not try to self-treat if you suddenly begin to experience possible preterm labor symptoms. 

You must see how long can preterm labor be delayed and when it’s time to take the next move….

The March of Dimes urges:

Call your health care provider or go to the hospital right away if you think you are having preterm labor. The signs of preterm labor include:

  • Contractions (your abdomen tightens like a fist) every 10 minutes or more often
  • Change in vaginal discharge (leaking fluid or bleeding from your vagina)
  • Pelvic pressure—the feeling that your baby is pushing down
  • Low, dull backache
  • Cramps that feel like your period
  • Abdominal cramps with or without diarrhea
