GLP-1 drugs and pregnancy: Who may face higher preterm birth risk

Weight loss drugs have been linked to an increased risk of premature births among women who took them inadvertently just before or during early pregnancy to treat pre-existing diabetes. However, a large study of over 750,000 pregnancies found that there was no link to preterm births or other obstetric complications if the medication was being used to lose weight. The authors of the study, published in Human Reproduction Open, say their findings suggest that it is diabetes rather than the drugs that may be contributing to the increased risk of preterm births.
