Popular weight loss and diabetes medications are once again under scrutiny, this time for their possible effects during pregnancy. A large new study suggests that women with pre-diabetes who take these drugs early in pregnancy may face a higher risk of preterm birth. The findings are particularly important because drugs such as semaglutide and other GLP-1 receptor agonists are increasingly being used not only for diabetes but also for weight management. As their popularity increases, so does concern about their safety during pregnancy, especially in the case of unplanned exposure.
What the study found
The study analyzed data from more than 750,000 pregnancies, making it the largest study to date to examine this issue. The key complication was the most significant, which states that women who use this drug to manage pre-existing diabetes and are exposed early in pregnancy have an increased risk of preterm birth. The increased risk was estimated to be about 70% higher in those who were not exposed. However, there was an important difference. When the same drug was used purely for weight loss, researchers found no significant association with preterm birth or other major pregnancy complications.
This suggests that the underlying condition, time of exposure, or metabolic factors play a more important role than the drug alone.

Why is preterm birth important?
Preterm birth, defined as birth before 37 weeks of pregnancy, is a major health concern. Babies born too early are at risk of:
- Breathing difficulties
- Developmental delays
- Chronic health complications
Prevention of preterm birth is therefore a key focus in maternal health care. Even modest increases in risk can have significant public health implications.
Why can diabetes risk change?
One of the most important insights from the study is that pre-existing diabetes itself can affect pregnancy outcomes. Women with pre-diabetes are at a higher risk of complications, including premature birth, due to factors such as:
Adding weight-loss drugs to the mix, especially in early pregnancy, may further alter metabolic processes, potentially increasing the risk. The researchers suggest that an interaction between the drug and the underlying disease could explain why the risk is seen in people with diabetes but not in people who use the drug only for weight loss.
A question of time
Time seems critical. The increased risk was mainly associated with women who were exposed to these drugs before or during pregnancy, often unintentionally. This is important because many pregnancies are unplanned, and some women may take weight loss or diabetes medications without realizing they are pregnant. Current medical guidelines generally recommend discontinuing GLP-1 drugs before pregnancy, as their effects on the developing fetus are not fully understood.

What about other pregnancy risks?
Interestingly, the study did not find strong evidence that this drug is associated with other major birth complications when used for weight loss. This suggests that drugs themselves do not universally increase pregnancy risks, but that specific clinical conditions, such as diabetes, are more important. Still, other studies have raised concerns about a wide range of pregnancy-related consequences associated with these drugs, including:
This indicates the need for careful monitoring and personal care.
What the experts say
Researchers and doctors urge caution, especially for women of childbearing age who take this drug. Key recommendations include:
- Avoid use during pregnancy
- Planning medication changes before trying to conceive
- Consult your doctor if you become pregnant during treatment
Given the increasing use of these drugs globally, experts say awareness is crucial. Many patients may not fully understand the potential side effects of pregnancy.
Limitations and what we don’t know yet
Despite its large size, the study has limitations. It is observational, meaning it shows a correlation, not direct cause and effect, and it cannot fully account for all factors, such as diabetes or lifestyle differences.
More research is needed to understand how these drugs interact with pregnancy, especially in different populations. Recent evidence suggests that weight loss and diabetes medications may increase the risk of preterm birth in women, especially when exposed early in pregnancy. However, the same risk was not observed when the drug was used only for weight loss, indicating the importance of individual health conditions. As the use of this drug continues to grow, the findings highlight an important message: Women who plan to become pregnant, or who may become pregnant, should carefully discuss this treatment with their health care provider. Meanwhile, researchers are calling for more studies to better understand how to balance the benefits of these drugs with their potential risks during the most sensitive period of life.
