Semaglutide Use During Pregnancy: What You Need to Know

An in-depth look at the risks, benefits, and considerations for using semaglutide to manage diabetes during pregnancy

For expectant moms, caring for their health and the baby's development is top priority. For women with type 2 diabetes, managing blood sugar during pregnancy requires difficult decisions about medication use that weigh both risks and benefits

One drug you may consider is semaglutide, but how much do you know about what it is and how it works?

What Is Semaglutide and How Does It Work?

Semaglutide belongs to a class of drugs called GLP-1 receptor agonists. Semaglutide works by stimulating the GLP-1 receptors in your pancreas, which are responsible for regulating insulin and glucagon.

Glucagon is the hormone that raises blood sugar, while insulin lowers it. Semaglutide increases insulin secretion and decreases glucagon secretion based on your blood glucose levels, which helps lower your A1C and blood sugar.

In everyday terms, semaglutide helps your pancreas know how much insulin to produce and release at the right times based on the foods you eat and your body's needs. 

For many women with diabetes, semaglutide can be an effective way to achieve target blood sugar goals, especially important for controlling diabetes during pregnancy. 

However, its impacts on a developing baby are still not fully known, which is important to consider when making choices about medication use in pregnancy. Discussing all your options with trusted health experts is key.

Potential Benefits of Semaglutide During Pregnancy

While semaglutide use during pregnancy comes with risks to consider, it may also provide benefits that lead to better health for both mother and baby. 

For women unable to control their diabetes well with insulin alone, semaglutide could help support a healthier pregnancy by providing tighter blood sugar management and an alternative option for care.

Tighter Blood Sugar Control

Semaglutide works to lower blood sugar levels and A1C, which can help achieve target goals for diabetes management in pregnancy. Controlling blood sugar, especially in early pregnancy, reduces the risk of birth defects and other complications that could affect the baby.

Studies show women with higher A1C levels have a higher chance of miscarriage, birth defects, preterm birth, and other issues. By using semaglutide to control blood sugar, especially right away, women may decrease risks to the fetus during this critical development stage.

Potential To Support a Healthier Pregnancy

Tighter blood sugar control is linked to benefits like fewer pregnancy losses, longer gestation, and lower chances of preterm birth. For my patients on semaglutide, better outcomes are often seen compared to those not taking anything or struggling with control on insulin alone. 

While medication risks remain, the benefits of sustained blood sugar management may lead to an overall healthier pregnancy with the best chances of delivering a healthy baby.

Option for Women Unable To Use Insulin

For some expectant mothers, semaglutide could be preferable or a better choice than insulin injections alone during pregnancy. Certain patients have trouble tolerating insulin, face risks like obesity that semaglutide also helps address, or can’t use insulin for other reasons.  

GLP-1 agonists provide an alternative, though risks to the fetus still must be carefully weighed for each patient based on their unique medical situation and stage of pregnancy. Frequent monitoring and timely adjustments to treatment may help minimize risks, but they cannot be entirely eliminated given the current limited research.

Determining if Semaglutide is Right for You During Pregnancy

To decide if semaglutide fits into your diabetes management and pregnancy care plan, discuss the benefits and potential risks thoroughly with your healthcare team. 

Your endocrinologist and OB-GYN can review your medical history, blood sugar levels, stage of pregnancy, and overall health to determine if semaglutide may be helpful for you and the baby or if alternative options like insulin alone would be safer based on your unique situation.

If used, closely monitor your progress with extra appointments, tests, and diabetes and pregnancy education. Report any issues like abnormal blood sugar readings, side effects, or concerns immediately so your doctors can make timely adjustments to treatment. Your health and your baby’s well being rely on vigilant management and care.  

Semaglutide may need to be stopped if risks start to outweigh benefits, especially during the first trimester when fetal development occurs rapidly. However, discontinuing any medication requires guidance from your doctor to avoid risks like fluctuating blood sugar. 

They will determine the best way to transition you to alternative treatment while keeping close tabs on your progress through frequent blood sugar checks, ultrasounds, and office visits. 

Close collaboration with your endocrinologist and OB-GYN, honest reporting of your experiences, and a willingness to make changes as needed are essential to using semaglutide safely during pregnancy or switching to alternative options if required based on your health and pregnancy stage. 

An open, flexible approach will help achieve the goal of the healthiest pregnancy possible in the face of diabetes. 

FAQ About Semaglutide and Pregnancy:

Should pregnant women or those planning pregnancy use semaglutide for treatment of type 2 diabetes? 

Pregnant women or those planning pregnancy should consult their healthcare provider before using semaglutide. 

Animal studies have shown potential risks to the fetus from exposure to GLP-1 receptor agonists like semaglutide. Although there are potential benefits of tighter blood sugar control during pregnancy, the risks of adverse fetal outcomes or pregnancy losses are unknown for semaglutide. 

Health care providers can determine if the benefits outweigh the risks for each pregnant patient based on their treatment plan.

How does semaglutide work and how can it benefit pregnant women with diabetes?

Semaglutide is a GLP-1 receptor agonist that works by increasing insulin secretion and decreasing glucagon secretion based on blood glucose levels. This can help lower blood sugar and A1C levels which provides potential benefits for diabetes management during pregnancy. 

Tighter control of blood glucose and A1C early in pregnancy can reduce the risk of birth defects and support a healthier pregnancy. However, the effects of semaglutide on fetal development and long-term outcomes are still unknown. 

Pregnant women should work closely with their healthcare providers to determine if semaglutide fits into their diabetes in pregnancy program.  

Are there any risks associated with taking semaglutide during pregnancy? 

There are potential risks to the fetus associated with taking semaglutide during pregnancy. Animal studies have shown adverse effects on embryo-fetal development with other GLP-1 receptor agonists. Although studies in humans are limited, there is a possibility of adverse reactions like major birth defects or developmental abnormalities. 

Semaglutide may also affect maternal factors like blood pressure, blood sugar levels, and weight which can indirectly impact the fetus. The risks seem to be greater during the first trimester, so women of childbearing age should use effective birth control while on semaglutide and stop the drug if pregnancy is detected. 

However, stopping semaglutide abruptly can also lead to risks, so patients should consult their health care provider right away if pregnancy occurs.

How Will My Doctor Determine if Semaglutide Is Right for Me During Pregnancy?

To determine if semaglutide is appropriate during your pregnancy, your doctor will consider several factors:

  • Your blood sugar levels and A1C before pregnancy: Tighter control may provide benefits, but risks may outweigh benefits if levels were already well-controlled before pregnancy. 
  • Your weight and any obesity-related health conditions: Semaglutide could provide benefits for chronic weight management, but may not be optimal during pregnancy
  • Your pregnancy category and stage: Risks seem highest in the first trimester, so your doctor will determine if benefits outweigh risks at your current stage of pregnancy.   
  • Alternative treatment options: Oral medications or changing insulin treatment may provide similar benefits with less risk during pregnancy compared to semaglutide. 
  • Your overall health: Conditions like diabetic retinopathy, kidney problems, or heart disease could impact the risk-benefit analysis for semaglutide use during your pregnancy.
  • Your doctor's experience with semaglutide and diabetes in pregnancy: Board-certified endocrinologists and OB-GYNs with experience managing GLP-1 agonists and diabetes during pregnancy will be able to provide the best guidance.  

Your doctor will weigh all these factors carefully to determine if semaglutide fits into a comprehensive treatment plan focused on a healthy pregnancy and the best outcomes for you and your baby. Be sure to report any issues or concerns right away to your entire care team.
