Will this medication affect my periods?

Some women report changes to their periods when they start GLP-1 medications. Your cycle might become irregular, arriving earlier or later than usual, or the timing might become unpredictable. You might notice that your bleeding is heavier or lighter than normal. In some cases, periods might become less frequent or even stop altogether for a while. The medications themselves do not directly interfere with your hormones in the way that the contraceptive pill does. However, rapid weight loss affects your hormones. Fat cells produce and store hormones, particularly oestrogen. As you lose fat, these hormones are released, and your body needs time to adjust. If you notice significant changes, please have a chat with your doctor.
