Reported by some women during rapid weight loss experience Menstrual Changes while taking Wegovy, which means it is far from unusual.

Why does Wegovy cause Menstrual Changes?

Rapid weight loss alters oestrogen levels and hypothalamic-pituitary-ovarian axis function. This is a direct consequence of how GLP-1 receptor agonists work — the same mechanism that drives weight loss and blood sugar control also affects gut motility and the body's response to food. The brain and gut are closely connected through the vagus nerve, and GLP-1 receptors are found throughout this system. Menstrual Changes tends to be most pronounced at the start of treatment and during dose increases because the body needs time to adapt to the new signalling environment. As GLP-1 receptor sensitivity adjusts over weeks, most patients find that menstrual changes becomes significantly more manageable even on the same or higher dose.

The body typically adapts to Wegovy over several weeks as GLP-1 receptors adjust to the presence of the medication. This adaptation process explains why Menstrual Changes and most other GLP-1 side effects are most pronounced during the initial weeks of treatment and during dose increases, then tend to improve with continued use. Starting at the lowest dose and increasing slowly is the most effective strategy for minimising Menstrual Changes during this adaptation period.
