Polycystic Ovary Syndrome (PCOS) is a common hormonal disorder affecting 1 in 10 women in the UK. It is often linked to insulin resistance, weight gain, and metabolic issues, making weight management a crucial part of managing the condition.
Mounjaro is a once-weekly injectable medicine approved for weight loss and type 2 diabetes in the UK. It targets two key hormones that help control blood sugar levels and reduce appetite. This makes the body more sensitive to insulin, lowers blood sugar, and aids in weight loss.
According to research, Mounjaro helps treat and manage PCOS symptoms, such as insulin resistance and obesity.
Polycystic Ovary Syndrome (PCOS) is a common hormonal disorder that affects women of reproductive age. It occurs when the ovaries produce an excess amount of androgens (male hormones), leading to hormonal imbalances that disrupt the menstrual cycle and cause various health issues. PCOS can affect fertility, metabolism, and overall well-being.
PCOS symptoms vary from person to person, but common signs include:
Many women with PCOS struggle with unexplained weight gain, especially around the abdomen.
The body becomes less responsive to insulin, leading to high blood sugar levels. It increases the risk of type 2 diabetes and metabolic disorders.
PCOS can cause irregular ovulation or lack of ovulation, making it difficult to conceive. It is one of the leading causes of infertility in women.
Women with PCOS often experience mood swings, depression, anxiety, and low energy levels.
Dark, velvety skin patches, usually on the neck, underarms, or groin, are linked to insulin resistance.
The exact cause of PCOS is not fully understood, but several factors contribute to its development:
Increased levels of androgens (male hormones) prevent the ovaries from releasing eggs, leading to irregular periods and fertility issues.
The body’s inability to use insulin properly causes higher insulin levels, which trigger more androgen production, worsening PCOS symptoms.
PCOS often runs in families, meaning you are more likely to develop it if your mother or sister has it.
Low-grade inflammation can cause the ovaries to produce excessive androgens, leading to hormonal imbalances and weight gain.
Women with Polycystic Ovary Syndrome (PCOS) are at a higher risk of developing several health conditions, including:
Mounjaro is a prescription-only injectable medication containing tirzepatide, approved for the management of type 2 diabetes and weight loss.
Although Mounjaro is not licensed to treat PCOS, your healthcare provider may prescribe it if you meet the eligibility criteria because it will help your PCOS symptoms.
Mounjaro (Tirzepatide) is a dual-action GLP-1 and GIP receptor agonist. It helps regulate blood sugar and appetite by:
Injecting Mounjaro once a week works the same way each time. This means it treats obesity by keeping you fuller for longer and reducing your appetite, so you can eat fewer calories without constantly feeling hungry. It also helps regulate blood sugar levels, making it easier to manage type 2 diabetes.
There is no definitive cure for PCOS, but its symptoms can be effectively managed through lifestyle changes, medications, and medical treatments. The goal is to regulate hormones, improve insulin sensitivity, and reduce associated health risks.
Mounjaro for PCOS can help in several ways, such as weight loss and treating insulin resistance, leading to better weight management, symptom improvement, and enhanced fertility.
50%-90% of women with PCOS and obesity struggle with insulin resistance, which can lead to weight gain and high blood sugar. Mounjaro helps increase insulin sensitivity, lowering blood glucose levels and reducing the risk of Type 2 diabetes.
If you have PCOS, you may find it harder to lose weight, and much of this is linked to insulin resistance. When your body struggles to use insulin effectively, it stores more fat, particularly around the abdomen, making losing weight even more challenging.
According to the NHS, losing just 5% of your body weight can significantly improve PCOS symptoms, including menstrual irregularities, insulin resistance, and excess androgen levels. This is why weight loss is often one of the first treatment recommendations for women with PCOS who are overweight or obese.
Mounjaro (tirzepatide) can be a game-changer for women with PCOS who have struggled to lose weight despite making lifestyle changes. It is prescribed alongside a healthy diet and exercise plan to enhance weight loss efforts and improve PCOS-related symptoms.
