*TRIGGER WARNING: Miscarriage*
Ask an Expert Question: Reoccurring loss, I’ve had 2 miscarriages back to back… fertility appointment is not until August/September… should I try again or wait? What can I do to decrease the chance of miscarriage?
Preventing miscarriage – what can be done?
Trying to get pregnant is not always a walk in the park. In fact, 1 in 6 Canadian couples struggle with infertility, and this number is on the rise. The harsh reality is that up to 15% of all clinical pregnancies end in a spontaneous miscarriage (1). Recurrent pregnancy loss (RPL), is when a woman has suffered 2 or more consecutive pregnancy losses, and may affect as many as 5% of couples who are trying to conceive (2, 3).
When a couple is ready to try (or try again), there are steps that can be taken to ensure their best chances of carrying a healthy pregnancy to term. As a fertility-focused Naturopathic Doctor, my role is to address the lifestyle factors that optimize pregnancy outcomes.
What factors cause miscarriage?
Causes of miscarriage are complex and varied, and for some couples a cause is difficult to identify. That being said, we should be asking the right questions.
The following causes should be considered:
1) Chromosomal factors
The vast majority of miscarriages result from of a chromosomal abnormality of the embryo (1). Genetic screening, or karyotyping, may be an option, particularly if a couple has suffered two or more miscarriages. Assessing ovarian reserve is another important tool in predicting risks for early pregnancy loss.
2) Uterine changes
This includes changes in the shape of the uterus (for example, a uterine septum is a tissue that may divide, or partially divide the uterus) or other abnormalities (fibroids, polyps, scarring or adhesions). We can also include thin uterine lining in this category. These changes may be detected on a pelvic ultrasound or sonohysterogram, which allows a detailed visualization of the inside of the uterus.
3) Hormone imbalances
In as many as 20% of recurrent miscarriages, a hormone imbalance may be to blame (1).
Progesterone plays a critical role in supporting receptivity of the uterine lining, enhancing the chances of implantation (10) and is involved in immunomodulatory changes which favour this process as well (1). Women with a history of recurrent pregnancy loss are sometimes prescribed progesterone during the first trimester (8, 11).
Thyroid and thyroid autoimmunity
Thyroid function should be investigated for all women who are trying to conceive, as suboptimal thyroid levels and thyroid autoimmunity are common factors that can contribute to miscarriage, if they are not addressed.
PCOS, or Polycystic ovary syndrome, is the most common hormone condition in women, and is associated with endocrine, metabolic and inflammatory changes; all of which may contribute to the risk of miscarriage. The recommended first-line treatment for PCOS women is lifestyle modifications, including nutrition and exercise. Addressing the risk factors of PCOS is one of the main areas that I treat in clinical practice.
4) Metabolic factors
Metabolic risk factors for pregnancy loss include insulin resistance or diabetes, both of which can be better managed with Naturopathic medicine.
5) Autoimmune and clotting disorders
Autoimmune diseases, including Lupus, Celiac disease or Hashimoto’s thyroiditis, can increase the risk of miscarriage, as can conditions affecting blood clotting, such as Antiphospholipid syndrome, Factor V Leiden or MTHFR gene mutations.
Infections, including ureaplasma, mycoplasma and others, are associated with a risk of miscarriage or preterm delivery (4), and are especially important to rule out if a woman has suffered a late pregnancy loss. Assessing the uterine microbiome can detect whether there are enough healthy bacteria present, as well as rule out the presence of infection.
7) Lifestyle factors
How does our lifestyle affect miscarriage risk?
Multiple lifestyle factors can significantly influence the risk of miscarriage. These include improper diet, nutrient deficiencies, body weight, caffeine, alcohol, drugs, smoking and exposure to toxins or environmental pollutants, particularly endocrine disrupting chemicals. As an example, a high caffeine intake (>200 mg/d) has been linked to miscarriage, and this link is particularly strong in women with a history of prior miscarriage (5). Simple and achievable lifestyle changes can make a difference not only to achieving a pregnancy, but also in carrying to term. Paying particular attention to these factors during the preconception period offers is crucial.
I am an advocate for Preconception care for both parents-to-be during the 3-6 months prior to trying to conceive. Preconception care, or making purposeful and healthful choices in the months leading up to pregnancy, can not only support egg and sperm quality to impact the chances of a successful pregnancy; but will also program the future health of the child.
