Causes of Miscarriage Before 12 Weeks: What Most Doctors Miss

Causes of Miscarriage Before 12 Weeks: What Most Doctors Miss

If you’ve had early miscarriage before 12 weeks, especially more than once, and been told everything looks “normal,” or you’ve been diagnosed with low AMH, high FSH, this episode is for you.

We’re going to talk about what’s often overlooked in early term pregnancy loss: gut health, immune dysfunction, clotting disorders, nutrient deficiencies, and hormone imbalance from a conventional and functional medicine perspective.

In this episode, you’ll learn:

Why progesterone, thyroid function and adrenal health are key to early pregnancy

The role of gut dysbiosis, inflammation, and food sensitivities in recurrent miscarriage

What comprehensive bloodwork reveals - including homocysteine, hsCRP, ANA, and more

Functional strategies to support detoxification, reduce stress, and improve implantation

How immune triggers and vaginal microbiome imbalances increase miscarriage risk

While the focus of this episode is on the female side of fertility, it’s not to be overlooked to look at the male partner’s health. Poor sperm quality, oxidative stress, gut infections, and DNA fragmentation can all contribute to miscarriage, poor embryo development,t and implantation failure. Just as we look at gut health, inflammation, and functional bloodwork in women,n we need to apply this lens to the male partner. If you haven’t looked at semen analysis or functional testing for men, be sure to check out our Male Factor Fertility episode for strategies to optimize sperm health and improve pregnancy outcomes.
