What does the source cover?
JD BioWorks reviews studies of GLP-1 medicines when becoming pregnant and in early pregnancy. Its article distinguishes accidentally taking a medicine early in pregnancy from continuing treatment throughout pregnancy.
How should the findings be read?
A 2026 systematic review did not find a clear increase in major birth defects in the groups studied, but rated confidence in the evidence as low. That result does not rule out every risk or apply identically to every drug.
Breast-milk studies answer a different question from pregnancy studies. For a personal exposure concern, a pregnancy-care clinician or prescriber can check the medicine, timing, and medical history. The source article explains the evidence and its limits; it does not establish safety for research material.
“Those results do not establish safety.”
