Does GLP-1 medication affect menstrual cycles or hormone-related symptoms?

Weight loss itself, regardless of the method, can affect menstrual cycles. For some, particularly those with PCOS-related irregular cycles, significant weight loss has been associated with more regular ovulation and cycles, sometimes even affecting fertility (this has been discussed in the context of unexpected pregnancies among people on GLP-1 medications, sometimes referred to informally as "GLP-1 babies," linked to improved ovulation rather than the drug directly acting on the reproductive system). Whether the medication itself has direct hormonal effects beyond what's driven by weight change isn't fully established, so any specific cycle changes are worth discussing with a provider rather than assuming either way.

Mine actually became way more regular after a few months, went from pretty unpredictable to almost clockwork. Wasn't expecting that side benefit honestly.
