Ozempic, whose active ingredient is semaglutide, was originally designed to help people with type 2 diabetes manage blood sugar levels. In recent years, though, it gained extraordinary popularity for its potential in supporting weight loss. Increasingly more women are using it, and with this comes an important question: Can Ozempic affect your period? Many began reporting changes in their menstrual cycles, which, of course, sparked interest in understanding the possible connection.
This article breaks down how Ozempic works, the reasons it may influence menstrual patterns, what changes you may notice, and when it's important to seek medical advice.

Ozempic is a GLP-1 receptor agonist, meaning it mimics the GLP-1 hormone that is naturally produced in the intestines. This hormone has several roles:
Since metabolism, insulin levels, and hormones are so closely linked, these effects have the potential to impact the reproductive system, too.
Many of them may wonder: Does Ozempic affect your period? While menstrual irregularities are not listed among the primary side effects, real-world experiences do indeed show some changes. As more women started using it for weight loss, online forums and even clinical observations noticed patterns such as:
This has raised questions like: Can Ozempic affect your menstrual cycle? Emerging evidence supports that metabolic changes can influence reproductive hormones.
Improved insulin sensitivity due to Ozempic can result in a modification in the levels of estrogen and progesterone. As these hormones regulate the menstrual cycle, even minor shifts may cause obvious changes.
Interestingly, some women with PCOS might actually experience improved menstrual regularity since GLP-1 drugs lower insulin, a major contributor to irregular periods in women with PCOS.

Sudden weight loss, as is common in the first weeks with Ozempic, may disrupt hormone production, leading to changes in regular menstrual cycles.
Insulin is strongly associated with ovulation; since Ozempic changes the way insulin responds, your cycle might change for a time.
Even positive changes, such as weight loss, can stress the body and lead to temporary menstrual irregularities.
If appetite decreases severely, you might be inadvertently consuming less. Iron, vitamin D, and essential fatty acid deficiencies can impact your cycle.
In fact, Ozempic can actually normalise periods for women with PCOS by helping balance insulin and androgens.
Many women describe the following changes within the first few weeks or months:
These are usually temporary and non-toxic.

Mild menstrual changes are common and usually settle within 2–3 months of starting the medication. However:
Remember, each body is different, and menstrual health is highly associated with lifestyle, metabolism, stress conditions, and hormonal balance in general.
Seek medical advice if you have:
Timely evaluation rules out other underlying conditions.
You may not be able to control every menstrual fluctuation, but you can support your body through the transition period.

So, does Ozempic affect your period? Yes, it may be for many women, especially those who experience sudden changes in weight or metabolic changes. Most menstrual disorders are quite temporary and settle as the body gets used to them.
However, if symptoms persist, cycles become highly irregular, or you're planning a pregnancy, it is necessary to consult with a doctor. Understanding how Ozempic interacts with reproductive health can help you use it safely and confidently.

The most common side effects are nausea, vomiting, and digestive disturbances.
It can temporarily cause menstrual irregularities due to hormonal changes associated with weight loss and insulin sensitivity.
Yes, some women have delayed, lighter, heavier, or irregular periods; however, this is usually temporary.
Ozempic influences insulin and metabolism, thus impacting estrogen and progesterone levels.
