Do you trust the safety of weight loss medications if taken shortly before becoming pregnant?
A systematic review of over two million pregnancies found that GLP-1 agonist weight loss medications did not increase risks of miscarriage, stillbirth, or birth defects when used around the time of conception. These findings provide new insight into the safety profile of these popular medications for those planning a family.
Why it matters
Current government guidelines advise against using these medications for two months prior to conception due to a lack of safety data. This research helps address those gaps by examining whether common concerns about birth outcomes are supported by current observational evidence.
This systematic review analyzed data from ten observational studies involving over two million pregnancies, including 8,325 women who used GLP-1 agonists within six months of conceiving. Researchers found no significant increase in risks such as miscarriage, premature birth, or birth defects.

The details
Researchers compared pregnancy outcomes for those using weight loss jabs near conception against those who did not. By aggregating data across studies, the review aimed to determine if the medication’s physiological effects on weight and metabolism interfered with fetal development. While the study found no increased adverse outcomes, the mechanism of these drugs in early pregnancy remains a focus for researchers who emphasize the need for more data, particularly at higher doses.

Health Landscape
Current government guidelines maintain a precautionary stance by advising against medication use during pregnancy and two months prior to conception. This study offers a preliminary, large-scale look at safety data, potentially serving as a foundation for future clinical practice updates.
If you are using these medications and planning to conceive, it is important to discuss current government advice with your doctor, as experts still recommend stopping injections before pregnancy. The study findings reinforce the need for ongoing conversations with your physician regarding your specific treatment plan.
The takeaway
While this review indicates no increased risk of complications, current medical advice remains to discontinue these injections before a planned pregnancy. Always consult your physician to weigh these findings against your specific health needs and medication history.
