- 0:11for joining us today. Yeah. So today we are putting
- 0:14a singular focus on a really critical intersection
- 0:17in the medical field right now, which is navigating
- 0:19GLP-1 medications and pregnancy. Right, because
- 0:22as prescribing rates for these medications keep
- 0:25rising, we're looking at a pretty massive evidence
- 0:27gap regarding maternal and fetal safety. Exactly.
- 0:31And to set the stage for you, we have to look
- 0:34at the current landscape. According to Dr. D.
- 0:36Yvette LaCoursiere, who is the lead author of newly
- 0:39released guidance from ACOG. That's the American
- 0:42College of Obstetricians and Gynecologists, just
- 0:45for anyone unfamiliar with the acronym. Right,
- 0:47ACOG. Well, according to her, as many as 1 in
- 0:50300 women are currently exposed to GLP-1s prior
- 0:53to pregnancy. 1 in 300. I mean, that is a staggering
- 0:57number when you zoom out. And with these medications
- 0:59becoming increasingly accessible online and at
- 1:02medical spas, that exposure likelihood is just
- 1:05heightening. It really is. And that's exactly
- 1:07what prompted ACOG to release specific recommendations
- 1:10for clinicians. So let's start with the period
- 1:13before pregnancy even begins. Preconception.
- 1:16ACOG's specific recommendation to clinicians
- 1:18is that they should consider having patients
- 1:20stop GLP-1 medications one to two months before
- 1:24trying to conceive. Yeah, one to two entire months.
- 1:27Which, you know, feels like a really long time
- 1:29to just wait after stopping a drug. But it makes
- 1:32sense if you think about it like an engine. It's
- 1:34kind of like letting the engine fully clear out
- 1:37before starting a completely new journey. That's
- 1:39a great way to visualize it, yeah. Because of
- 1:41the long half-lives of these medications, it
- 1:44takes weeks for the body to actually fully clear
- 1:46them. It's not an overnight thing. Right. You
- 1:48can't just stop taking it on a Friday and be
- 1:50clear by Monday. Exactly. And ACOG also brings
- 1:53up a really important point about fertility here.
- 1:55Oh, right. Because the weight loss associated
- 1:57with GLP-1s can actually improve fertility.
- 2:00Yes. Both spontaneous and assisted conception
- 2:03can improve. So ACOG recommends that clinicians
- 2:05need to speak with patients who do not wish to
- 2:08become pregnant about using reliable contraception.
- 2:11Because obviously, if you're on the medication
- 2:12and suddenly your fertility improves, you could
- 2:15find yourself in a situation where you get pregnant
- 2:17before you even have a chance to do that one
- 2:20to two month clearance window. Precisely. It's
- 2:22a huge clinical consideration right now. OK,
- 2:25so that logically leads us to the next big question.
- 2:28If clinicians are advising patients to stop the
- 2:32medication before getting pregnant, what are
- 2:34the actual physical effects of that discontinuation?
- 2:38Well, this is where a newly published study in
- 2:40JAMA by Maya et al. comes into play. Okay, let's
- 2:43unpack that. But we need to strictly frame this
- 2:46first. This is an observational study. It found
- 2:49an association. It is absolutely not proof that
- 2:52stopping the drugs causes harm. Right. That distinction
- 2:55is so important for you listening. It's an association,
- 2:59not a direct proven cause. Exactly. So looking
- 3:03at the exact findings, they looked at a cohort
- 3:05composed primarily of women with obesity. Okay.
- 3:09And those who were prescribed GLP-1s with discontinuation
- 3:13before or in early pregnancy experienced a mean
- 3:17gestational weight gain of 13.7 kilograms. 13.7
- 3:21kilograms. Okay. But how does that compare
- 3:24to people who weren't on the drug? So they looked
- 3:26at propensity-matched unexposed pregnancies,
- 3:29and in that group, the mean weight gain was 10.5
- 3:31kilograms. Okay, so that's a difference of
- 3:343.3 kilograms. Right, exactly. The exposed group
- 3:37gained 3.3 kilograms more, but did that translate
- 3:41to other risks? It did. The study listed specific
- 3:44comparative figures for the exposed group versus
- 3:47the unexposed group. For instance, there was
- 3:49a higher risk of preterm delivery. It was 17%
- 3:52versus 13%. Okay. And for gestational diabetes,
- 3:56it was 20% in the exposed group compared to
- 3:5815% in the unexposed. Wow. Yeah. And for hypertensive
- 4:02disorders of pregnancy, they saw 46% compared
- 4:06to 36%. Wait, I have to jump in here. If they
- 4:09stop taking the drug, are these higher risks
- 4:12actually being caused by the medication exposure?
- 4:14Or is this just the body rebounding after an
- 4:16obesity treatment is removed? That is the crucial
- 4:19question. And it highlights a key limitation
- 4:21of the Maya et al. study. Oh, really? How so?
- 4:25Well, the researchers matched patients based
- 4:27on their pre-pregnancy BMI. They did not match
- 4:31them based on their BMI from before they started
- 4:33the GLP-1 treatment. Oh, I see. So you're looking
- 4:36at someone who maybe just lost a lot of weight
- 4:38on the drug and comparing them to someone who
- 4:41naturally maintained that same BMI without the
- 4:43drug. Exactly. The metabolic baselines are completely
- 4:47different. And this actually aligns perfectly
- 4:49with ACOG's caution to clinicians. Which is that
- 4:52regaining weight after discontinuation is common,
- 4:55right? Yes. ACOG notes that this rebound weight
- 4:58gain is common and may increase the risk of adverse
- 5:01outcomes. Which is why they encourage clinicians
- 5:04to really monitor their patient's weight and
- 5:06counsel them on lifestyle interventions during
- 5:08that period. You can't just stop the drug and
- 5:11walk away. Right. It requires very active management.
- 5:14Okay. So moving the timeline forward chronologically.
- 5:18What does ACOG tell clinicians to do once a patient
- 5:21is actively pregnant? ACOG's guidance here is
- 5:23very clear. Clinicians are advised against the
- 5:26use of GLP-1s during pregnancy except within
- 5:29a clinical trial. And I just want to clarify
- 5:31that language really quickly for you listening.
- 5:33They are strongly recommending against it to
- 5:36clinicians based on a lack of data, but they
- 5:38never actually call it a firm prohibition or
- 5:41a ban. That's a great point. It's not an outright
- 5:43ban, but the why behind the guidance is pretty
- 5:46compelling. Right, because of the animal studies.
- 5:48Yes. ACOG attributes their reasoning directly
- 5:51to animal studies, which showed associations
- 5:53with decreased fetal weight, growth restriction,
- 5:56and abnormal bone development. Yeah, which obviously
- 5:59raises immediate concerns for human pregnancies.
- 6:01Definitely. And additionally, ACOG points out
- 6:04that GLP-1 use could result in inadequate intake
- 6:07of nutrient-dense foods. Oh, because the medication
- 6:10makes you feel full so quickly. Exactly. So patients
- 6:12might not get the essential vitamins and minerals
- 6:14that are just vital during a pregnancy. That
- 6:16makes total sense. You physically just can't
- 6:18eat enough of the good stuff. But to add some
- 6:20balance here, what does ACOG say about the human
- 6:23data we actually do have? Well, ACOG notes that
- 6:26available human data has not demonstrated a consistent
- 6:29increase in birth defects. Which is somewhat
- 6:31reassuring. It is. And they also mentioned that
- 6:34because GLP-1s are large peptide molecules,
- 6:37transplacental passage is thought to be unlikely.
- 6:39Meaning the drug molecules are too big to easily
- 6:41cross the placenta to the fetus. Exactly. But
- 6:44even with that, the safety data we have is just
- 6:46far too limited right now. Hence the strong advice
- 6:49against use. Yeah, that makes sense. You just
- 6:52can't risk the unknowns. OK, so moving to the
- 6:55final stage of the timeline, the postpartum period
- 6:58and breastfeeding. Right. Lactation. What is
- 7:02ACOG advising there? For lactation, ACOG advises
- 7:05obstetricians to engage in shared decision-making
- 7:08with their patients. Meaning they need to sit
- 7:10down and create a customized postpartum care
- 7:12plan together. Yes, and that plan can potentially
- 7:15include GLP-1s. But there are some really crucial
- 7:18exceptions here that ACOG emphasizes, right?
- 7:20Very crucial. ACOG recommends against use while
- 7:24nursing preterm infants. Okay. And they also
- 7:27recommend against use for newborns in the first
- 7:2928 days of life. And I want to stress for you
- 7:32listening that ACOG stated those parameters without
- 7:34providing the underlying physiological reasons
- 7:36in this specific guidance. So we aren't going
- 7:39to guess or speculate as to why that 28-day
- 7:41window exists. Right. We just report what they
- 7:44advise the clinicians. Now, for infants outside
- 7:46that window, if a patient does use GLP-1s while
- 7:49breastfeeding, ACOG advises close surveillance.
- 7:52Meaning monitoring the infant's weight gain,
- 7:54right? Exactly. In close concert with the infant's
- 7:57healthcare professional, like their pediatrician.
- 7:59Okay. Did ACOG give any guidance on which specific
- 8:03medications might be preferred if they do decide
- 8:05to use them postpartum? They did mention that
- 8:08if a patient chooses to use GLP-1s while lactating,
- 8:11despite the limited data, it's prudent to select
- 8:14medications with shorter half-lives. Okay. Like
- 8:17what? They specifically used exenatide as an
- 8:20example. Right. And again, this is strictly what
- 8:23ACOG told clinicians to consider. It's definitely
- 8:25not a how-to guide or prescribing advice for
- 8:28you listening at home. Definitely not. It's just
- 8:30a clinical strategy they mentioned to help mitigate
- 8:33the unknown risks. You know, looking at this
- 8:36whole picture, it just reflects this incredible
- 8:38balancing act for both clinicians and patients
- 8:41right now. It really does. Everyone is kind of
- 8:44caught in this giant evidence gap. You're forced
- 8:47to weigh the really well-documented risks of
- 8:49obesity and that rapid rebound weight gain against
- 8:52the totally unknown variables of early GLP-1
- 8:55exposure. It's a tough spot to be in. It perfectly
- 8:58highlights how incredibly fast GLP-1 medicine
- 9:01is moving and how urgently maternal safety research
- 9:05just needs to catch up. Absolutely. The research
- 9:08just has to catch up to the reality on the ground.
