You can take Wegovy (semaglutide) if you have polycystic ovary syndrome (PCOS), provided you meet the eligibility criteria. PCOS isn’t listed as a contraindication in the Wegovy prescribing information.¹

PCOS affects approximately 1 in 10 women in the UK. Studies suggest that 50-70% of women with PCOS are overweight or obese, although prevalence varies depending on the population studied and diagnostic criteria used.²

The condition creates a cycle where hormonal imbalances promote weight gain, and excess weight worsens hormonal symptoms.

Insulin resistance, which affects up to 70% of women with PCOS regardless of body weight, promotes fat storage, particularly around the abdomen.

International guidelines recommend that losing 5-10% of body weight is one of the most effective first-line approaches for managing PCOS symptoms in women with overweight or obesity.² This makes effective weight management particularly relevant for women living with the condition.

What is PCOS?

Polycystic ovary syndrome is an endocrine condition that affects how the ovaries function. It’s the most common endocrine disorder in women of reproductive age, with a global prevalence of 6-13%.²

It’s characterised by at least two of the following: irregular or absent periods, elevated androgen levels (which can cause acne and excess hair growth), and polycystic ovaries on ultrasound.

Three interconnected issues are common in PCOS:

• Insulin resistance: affecting up to 70% of women with PCOS, regardless of body weight. This promotes fat storage, particularly around the abdomen, and makes it harder to lose weight through diet and exercise alone.
• Elevated androgen levels (hyperandrogenism): contributing to symptoms like acne, excess hair growth, and hair thinning
• Chronic low-grade inflammation: which may worsen insulin resistance and hormonal imbalances

These factors create a self-reinforcing cycle. Insulin resistance stimulates the ovaries to produce more androgens, which in turn promote central fat storage and worsen insulin resistance further.

How Wegovy may help with PCOS

Semaglutide is a GLP-1 receptor agonist that mimics a hormone our body naturally produces in the gut. It acts on the brain to reduce appetite and food intake, and also improves insulin sensitivity and blood sugar regulation.

While no large-scale trial has specifically studied Wegovy in PCOS, there’s growing evidence supporting GLP-1 receptor agonists in this population.

A 2024 meta-analysis of randomised controlled trials found that GLP-1 receptor agonists in women with PCOS led to significant reductions in BMI and waist circumference, a 33% reduction in testosterone levels, and improved menstrual regularity and ovulation rates.³

A 2025 meta-analysis of 8 randomised controlled trials (526 participants) that specifically examined semaglutide in PCOS confirmed significant reductions in BMI and improvements in lipid profiles, with greater effects at doses of 1.0 mg or higher per week.⁴

How weight loss improves PCOS

Medication interactions

Metformin

Metformin is commonly prescribed off-label for PCOS to improve insulin resistance. There’s no negative interaction between semaglutide and metformin, and the two can be co-prescribed.

A 2025 randomised controlled trial of 100 women with PCOS found that the combination of semaglutide and metformin produced significantly greater improvements in body weight, insulin resistance, inflammatory markers, and menstrual regularity compared to metformin alone. The combination group also had higher natural pregnancy rates during follow-up.⁵

Both medications can cause gastrointestinal side effects, so a slower dose escalation of Wegovy may be helpful if you’re already taking metformin.

Combined oral contraceptives

Many women with PCOS take the combined oral contraceptive pill to regulate periods and manage androgen-related symptoms.

A pharmacokinetic study confirmed that semaglutide doesn’t reduce the bioavailability of ethinylestradiol or levonorgestrel, so Wegovy shouldn’t affect the effectiveness of your contraceptive pill.¹ This is a relevant distinction from Mounjaro (tirzepatide), which has been shown to reduce oral contraceptive exposure by approximately 20%.

Spironolactone

Spironolactone is sometimes prescribed for PCOS to reduce androgen-related symptoms such as acne and excess hair growth. There’s no documented interaction between semaglutide and spironolactone, and the two can be used together.

Foods to focus on with PCOS and Wegovy

Eating to support stable blood sugar levels is particularly important with PCOS, as insulin resistance is central to the condition.

When taking Wegovy, your appetite will be reduced, so it’s important to ensure that you’re eating a diet based on nutrient-dense, whole foods to provide your body with everything it needs.

Protein at every meal

Protein helps maintain muscle mass during weight loss and supports stable blood sugar levels. Aim for a palm-sized portion at each meal.

Good options include:

• Chicken, turkey, and lean red meat
• Fish, particularly oily fish like salmon, mackerel, and sardines (also good sources of omega-3, which may help reduce inflammation)
• Eggs
• Greek yoghurt (if you tolerate dairy)
• Tofu and tempeh
• Lentils and chickpeas

Foods that support insulin sensitivity

Choosing foods that release energy slowly helps avoid the blood sugar spikes that worsen insulin resistance:

• Non-starchy vegetables: leafy greens, broccoli, courgettes, peppers, aubergines, tomatoes
• Complex carbohydrates: sweet potatoes, oats, quinoa, basmati rice, sourdough bread
• Healthy fats: avocado, olive oil, nuts, and seeds (walnuts and flaxseeds are particularly good sources of omega-3)
• High-fibre foods: beans, lentils, vegetables, and berries, which slow the absorption of sugar into the bloodstream

Anti-inflammatory foods

Chronic low-grade inflammation is a feature of PCOS, and while our overall diet and lifestyle will have a greater influence on managing inflammation than any single food, including foods with anti-inflammatory properties, may help:

• Oily fish (salmon, mackerel, sardines) at least twice a week
• Nuts and seeds, especially walnuts, almonds, and flaxseeds
• Berries, cherries, and pomegranates
• Leafy greens and cruciferous vegetables (broccoli, kale, spinach)
• Extra virgin olive oil
• Turmeric and ginger

Foods to limit

Some foods may worsen both insulin resistance and Wegovy side effects:

• Refined carbohydrates and added sugars (white bread, sugary cereals, pastries, sweets)
• Sugary drinks, including fruit juice
• Ultra-processed foods and takeaways
• Excessive caffeine can worsen anxiety, which is common in PCOS
• Alcohol (affects blood sugar regulation and can worsen nausea from Wegovy)

Managing nausea from Wegovy

If nausea is an issue, particularly during dose escalation:

• Eat smaller, more frequent meals rather than large portions
• Avoid lying down immediately after eating
• Choose easily digestible foods during the first few weeks (scrambled eggs, white fish, mashed potatoes, cooked vegetables)
• Ginger tea or ginger supplements may help settle your stomach

Physical activity

Regular exercise improves insulin sensitivity independently of weight loss, which is particularly beneficial for PCOS.

Aerobic exercise

Activities like walking, cycling, and swimming improve cardiovascular health and insulin sensitivity.

A systematic review found that vigorous aerobic exercise produced the most consistent improvements in insulin sensitivity markers in women with PCOS.⁶

Aim for at least 150 minutes of moderate-intensity activity per week, or 75 minutes of vigorous activity. Even brisk walking for 30 minutes most days can make a meaningful difference.

Resistance training

Resistance training (bodyweight exercises, free weights, or resistance bands) is particularly relevant for PCOS.

Research suggests it can reduce visceral fat, lower fasting glucose, and increase lean muscle mass in women with PCOS.⁷

More muscle mass increases your basal metabolic rate, meaning you burn more energy at rest. This is especially helpful when taking Wegovy, as maintaining muscle mass during weight loss protects your metabolism in the long term.

Aim for 2-3 sessions per week. You don’t need a gym membership to start. Bodyweight exercises like squats, lunges, press-ups, and resistance band work are all effective.

Other beneficial activities

Yoga has shown promising results for PCOS in early research, with potential benefits for both insulin resistance and androgen levels.⁶ It may also help manage the stress and anxiety that are common in PCOS.

There are no PCOS-specific restrictions on exercise while taking Wegovy. Focus on activities you enjoy and can maintain consistently.

Mental health and PCOS

PCOS is associated with significantly higher rates of anxiety and depression.

A systematic review found that women with PCOS have around 4 times the odds of moderate to severe depressive symptoms and over 5 times the odds of anxiety symptoms compared to women without the condition, even after accounting for differences in body weight.⁸

Several factors contribute to this. The visible symptoms of PCOS, such as acne, excess hair growth, and weight gain, can significantly affect body image and self-confidence. Difficulties with fertility add additional emotional pressure.

The hormonal imbalances themselves, including insulin resistance and elevated androgens, may also have direct effects on mood.

Managing a chronic condition that requires ongoing attention to diet, medication, and symptoms is also mentally demanding.

If you’re starting Wegovy alongside managing PCOS, it’s worth being aware that the early weeks of dose escalation can be physically uncomfortable, which may affect your mood.

What can help

• Speak to your GP if you’re experiencing persistent low mood, anxiety, or difficulty coping
• Regular physical activity has evidence behind it for improving mood in PCOS, alongside its metabolic benefits
• Peer support, whether through PCOS-specific communities or general support groups, can reduce the sense of isolation many women with PCOS describe
• Cognitive behavioural therapy (CBT) has evidence for managing anxiety and depression in chronic health conditions
• If you’re prescribed medication for anxiety or depression, there are no known interactions between common antidepressants and semaglutide

When to speak to your GP

Contact your GP or specialist if you experience:

• Changes in your menstrual cycle that concern you (either improvement or worsening)
• Persistent gastrointestinal side effects that affect your ability to take other medications
• If you’re planning to become pregnant, Wegovy should be stopped at least two months before conception¹
• Significant mood changes or worsening mental health symptoms
• Severe abdominal pain, which could indicate pancreatitis (rare but serious)
• Signs of dehydration include vomiting or diarrhoea that are persistent (dizziness, dark urine, extreme thirst)

Frequently asked questions

Is Wegovy approved for treating PCOS?

Wegovy isn’t licensed specifically for PCOS. It’s licensed for weight management in adults with a BMI of 30 or above, or 27 or above with at least one weight-related comorbidity.

If you have PCOS and meet these criteria, you may be eligible for Wegovy through specialist weight management services.

Will Wegovy help with my PCOS symptoms?

Research suggests that GLP-1 receptor agonists can improve several PCOS features, including insulin resistance, testosterone levels, menstrual regularity, and ovulation rates.³

These improvements are largely driven by weight loss, though semaglutide may also have direct effects on insulin signalling.

Can I take Wegovy with metformin for PCOS?

Yes. There’s no interaction between semaglutide and metformin. A 2025 randomised controlled trial found that the combination was more effective than metformin alone in improving weight, insulin resistance, and ovulatory status in PCOS.⁵ Both can cause gastrointestinal side effects, so a slower dose escalation may help.

Will Wegovy affect my fertility?

Weight loss in women with PCOS often improves ovulation and fertility. If you’re not trying to conceive, ensure you have reliable contraception in place, as improved ovulation means an increased chance of pregnancy.

If you are planning pregnancy, Wegovy should be stopped at least two months before trying to conceive.¹

Can I take Wegovy with the contraceptive pill?

Yes. Studies confirm that semaglutide doesn’t reduce the effectiveness of combined oral contraceptives containing ethinylestradiol and levonorgestrel.¹

Does PCOS make it harder to lose weight on Wegovy?

Insulin resistance, which is common in PCOS, can make weight loss more challenging. However, semaglutide directly improves insulin sensitivity alongside reducing appetite, which may help counteract this. The rate of weight loss may vary between individuals.

Is there a link between PCOS and type 2 diabetes?

Yes. Women with PCOS have a significantly higher risk of developing type 2 diabetes due to insulin resistance. Effective weight management can reduce this risk. If you have PCOS, your GP should monitor your blood sugar levels regularly.

Can Wegovy help with PCOS-related acne and hair growth?

These symptoms are driven by elevated androgen levels. Research shows that weight loss and GLP-1 receptor agonists can reduce testosterone levels in women with PCOS.³ Improvements in androgen-related symptoms may follow, though this varies between individuals and can take several months to become noticeable.

Can I get Wegovy on the NHS if I have PCOS?

Wegovy is available through NHS specialist weight management services under NICE TA875.⁹ PCOS itself isn’t an eligibility criterion, but if you meet the BMI and comorbidity requirements, you can be referred. Your GP can make the referral.

How long can I take Wegovy for PCOS?

NICE recommends Wegovy for a maximum of two years through specialist weight management services.⁹ The goal is to use the medication alongside lifestyle changes that can be maintained long-term. Private prescriptions may have different duration guidelines.

Take home message

Wegovy isn’t licensed specifically for PCOS, but women with PCOS who meet the weight management criteria may benefit from it.

Research suggests that GLP-1 receptor agonists can improve several features of PCOS, including insulin resistance, androgen levels, and menstrual regularity, largely through weight loss.

Because insulin resistance is central to PCOS, focusing on foods that support stable blood sugar levels, regular physical activity (including resistance training), and maintaining muscle mass during weight loss are all particularly important for women with this condition.

If you have PCOS and are considering Wegovy, discuss it with your GP or specialist. They can help determine whether it’s appropriate alongside your current PCOS management plan.
