GLP-1 medicines have not been extensively studied in relation to menstrual health, but some women report changes in their menstrual cycles after starting these medications. Factors like weight loss, hormonal changes, and improved overall health can influence menstruation. For some, weight loss may lead to more regular cycles, while others may experience irregularities. If you notice significant changes in your menstrual health after starting GLP-1 therapy, it's important to discuss this with your healthcare provider. They can help determine if the medication is a contributing factor and suggest appropriate adjustments.
