Losing weight with PCOS can feel frustrating, especially when insulin resistance, increased appetite and constant cravings make progress harder than it should be.
So when women like Tessy, who has insulin-resistant PCOS, lose 15kg on Mounjaro, it’s understandable why others want to know more.
But before you consider Mounjaro for PCOS weight loss, there are seven things you should know.
TL;DR: Seven Things to Know About Mounjaro for PCOS
-
Women diagnosed with PCOS can lose significant weight on tirzepatide. In a 2026 study, those who reached 10 months lost an average of 19.4% of their body weight.
-
Mounjaro contains tirzepatide, which acts on GIP and GLP-1 receptors to regulate appetite and blood sugar. It may help with weight, insulin resistance and appetite when you have PCOS.
-
Mounjaro may reduce food noise, with women reporting fewer persistent thoughts about eating.
-
Some women may experience more regular periods or changes in ovulation as their weight and metabolic health improve.
-
Mounjaro can cause side effects including nausea, vomiting, diarrhoea and constipation, particularly when starting or increasing the dose.
-
Mounjaro can help with the metabolic side of PCOS, but you may still need other treatments for insulin resistance, periods or fertility.

1. Mounjaro Doesn’t Treat PCOS, But It May Help With Some of Its Metabolic Problems
Metabolic problems like insulin resistance can make weight loss feel like an uphill battle for women diagnosed with PCOS.
For some women with PCOS, higher insulin levels can affect how the ovaries produce hormones and may contribute to symptoms such as irregular periods, acne and excess hair. Insulin resistance can also make weight management more difficult.
One Reddit user, redcat987, shared that they had severe insulin resistance before starting Mounjaro.
They also shared that they were no longer insulin resistant after treatment, while their A1C dropped from 5.9 to 4.7.
Mounjaro contains tirzepatide, which works on GIP and GLP-1 receptors involved in appetite and blood sugar regulation.
Here are four areas Mounjaro may actually help PCOS warriors with:
-
Weight Loss: If PCOS has made losing weight difficult, Mounjaro can help reduce your appetite, so you may find it easier to eat less and maintain the calorie deficit needed for weight loss.
-
Insulin resistance: Tirzepatide, the active ingredient in Mounjaro, Tizaro and compounded tirzepatide, can improve insulin sensitivity, helping your body respond to insulin more effectively. When your body doesn't respond to insulin properly, your pancreas produces more insulin to compensate. Higher insulin levels can affect hormone production and make weight management more difficult for some women with PCOS.
-
Blood sugar: Insulin resistance can make it harder for your body to move glucose from your blood into your cells for energy. Tirzepatide helps improve blood sugar regulation, which can be particularly relevant if insulin resistance or elevated blood sugar is part of your PCOS picture.
-
Appetite and cravings: PCOS and insulin resistance can sometimes come with persistent hunger. Mounjaro works on appetite-regulating hormones, which can help you feel fuller for longer and reduce how often you think about food.
PCOS doesn't only impact your ovaries. It can involve your hormones, metabolism and reproductive health too.
This is why, in 2026, PCOS was renamed Polyendocrine Metabolic Ovarian Syndrome (PMOS).
The new name recognises the hormonal, metabolic and reproductive changes that can come with the condition, rather than putting the focus mainly on the ovaries.

2. Mounjaro Can Support Weight Loss Even If You Have PCOS
A 2026 study looked at 4,241 women with self-reported PCOS who used tirzepatide.
Of these women, 40 reached the 10-month assessment and lost an average of 19.4% of their body weight.
Women without PCOS lost an average of 18.74%, so the difference was not significant.
In other words, having PCOS didn't appear to make tirzepatide less effective for weight loss in this study.
Of course, everyone responds differently. Your starting weight, dose, how long you stay on treatment and how your body responds can all affect your results.
At HueBeautyGlam, our client Tessy who was on Mounjaro told us Mounjaro made it easier for her to stay consistent and lose 15kg.

3. Mounjaro May Quiet the Constant Food Thoughts That Make Weight Loss Harder
Sometimes, the hardest part of losing weight is thinking about food all the time.
You eat breakfast and you're already wondering what you'll have for lunch. You finish lunch and start thinking about dinner. Then there's the snack you weren't planning to have but can't stop thinking about.
For some women with PCOS, that constant food noise can make staying consistent with weight loss even harder.
Tessy knows this feeling well. Before starting Mounjaro, she told us she spent a lot of time thinking about what she would eat for lunch, dinner or her next snack.
After starting Mounjaro, she noticed a completely different relationship with food. She said, “I think about food like a normal person now.”
A Reddit user shared a similar experience. k-gnar, who has lived with PCOS since her teenage years, had tried different forms of Metformin before starting Mounjaro after developing diabetes.
She reported losing 50 lb (22.7kg), along with improvements in her blood sugar, and said her food noise had stopped.

4. Mounjaro May Help Make Your Periods More Regular
If your periods have been irregular because of PCOS, you may notice them becoming more regular after starting Mounjaro. However, Mounjaro isn't prescribed specifically to regulate your periods.
As your weight and metabolic health improve, your insulin regulation may improve too.
For some women with PCOS, this can support more regular ovulation, which may lead to more regular periods.
redcat987, shared that she previously had severe bleeding for about a week.
After being on Mounjaro, she reported that her periods became shorter, lasting around three days with moderate flow.
k-gnar also shared a change in her periods after starting Mounjaro.
She said she had previously gone several months without a period and experienced prolonged, heavy bleeding.
After starting treatment, she reported getting her period twice, despite having an IUD.
So, if your periods have been irregular, losing weight and improving your metabolic health may help, but don't start Mounjaro expecting it to work as a period regulator.
5. Mounjaro May Affect Ovulation and Fertility
PCOS can interfere with regular ovulation, which is one reason some women with the condition have difficulty getting pregnant.
As Mounjaro helps with weight loss and metabolic health, it may also affect the hormonal changes involved in ovulation.
Early research into tirzepatide in women with PCOS has found improvements in areas such as menstrual regularity, insulin sensitivity and reproductive markers.
These research findings suggest that the benefits of tirzepatide may extend beyond weight loss and could have an impact on ovulation for some women.
There is also an important practical point if you're sexually active.
As your cycles become more regular, you may start ovulating more consistently, which means you can become pregnant even if getting pregnant was previously difficult.
If you're trying to conceive, speak with your healthcare provider about Mounjaro and your treatment plan.
NOTE: Mounjaro isn't recommended during pregnancy.

6. Mounjaro Has Side Effects You Should Know About
Like any medication, Mounjaro can cause side effects, especially when you first start treatment or increase your dose.
The most common ones include:
-
Nausea
-
Vomiting
-
Diarrhoea
-
Constipation
-
Abdominal discomfort
-
Reduced appetite
For many people, these effects are more noticeable when starting Mounjaro or moving up to a higher dose.
That's why Mounjaro is usually increased gradually rather than starting at a high dose immediately.
Giving your body time to adjust can make the treatment easier to tolerate.
7. You May Need Other PCOS Treatments Alongside Mounjaro
Starting Mounjaro doesn't necessarily mean stopping the other parts of your PCOS treatment.
What you need alongside it depends on your symptoms, health and what you're trying to achieve.
For example, your doctor may recommend:
-
Metformin if insulin resistance is a concern.
-
Hormonal contraception or other hormonal treatment if you're managing irregular periods or other hormonal symptoms.
-
Fertility treatment if you're trying to get pregnant and aren't ovulating regularly.
-
Treatment for acne or excess hair if these are part of your PCOS symptoms.
-
Healthy eating and physical activity to support your weight loss and overall metabolic health.
Mounjaro can be one part of your PCOS treatment plan, rather than the whole plan.
If you're already taking medication for PCOS, discuss your treatment with the HueBeautyGlam team to find out if Mounjaro can be added to your current plan.
