PCOS (Polycystic Ovary Syndrome) and insulin resistance are closely linked, with up to 80% of women with PCOS experiencing insulin resistance. This connection plays a key role in worsening symptoms like irregular periods, excess hair growth, and weight gain, while also increasing long-term risks for type 2 diabetes and heart disease.
Here’s what you need to know:
- PCOS Symptoms: Irregular cycles, high androgen levels (causing acne, hirsutism), and polycystic ovaries.
- Insulin Resistance: Cells don’t respond properly to insulin, leading to elevated blood sugar and insulin levels.
- The Cycle: Insulin resistance increases androgen production, worsening PCOS symptoms, while PCOS itself can contribute to insulin resistance.
- Health Risks: Women with PCOS and insulin resistance are 4-7 times more likely to develop diabetes.
- Treatment: Medications like metformin and GLP-1 agonists, combined with lifestyle changes (diet and exercise), can help manage symptoms and reduce risks.
Understanding your PCOS type (A, B, C, or D) can guide treatment choices. For example, phenotype B (irregular cycles + high androgens) has the highest insulin resistance rate (91.9%) and benefits most from insulin-sensitizing treatments. Platforms like Oana Health offer accessible, prescription-based solutions for managing PCOS and insulin resistance from home.
Takeaway: Early diagnosis and targeted treatments are key to breaking the cycle of PCOS and insulin resistance, improving symptoms, and preventing long-term complications.
Why Does Insulin Cause PCOS (Polycystic Ovary Syndrome)? – Dr.Berg
How PCOS and Insulin Resistance Affect Each Other
PCOS and insulin resistance are deeply interconnected, each making the other worse and creating a cycle that prolongs symptoms and complicates treatment. Let’s explore how these processes impact ovarian function and inflammation.
High Androgen Levels and Insulin Resistance
One of the defining features of PCOS is elevated androgen levels, which play a key role in insulin resistance. These hormones promote abdominal fat storage and disrupt how the body processes glucose. The central fat, in turn, releases inflammatory substances that interfere with insulin signaling. This sets off a harmful loop: insulin resistance leads to even higher androgen production. Women with the full-blown PCOS phenotype are 2.52 times more likely to experience insulin resistance compared to other types.
Insulin’s Impact on Ovarian Function
Insulin resistance doesn’t just stop at blood sugar issues - it directly affects ovarian health. High insulin levels push ovarian theca cells to produce more androgens, disrupt normal follicle development, and lower the liver’s production of SHBG (sex hormone-binding globulin). This results in higher levels of free testosterone, which throws ovarian function off balance. The consequences? Irregular menstrual cycles, anovulation, and the presence of multiple small cysts - immature follicles that fail to develop properly.
Inflammation and Weight Gain
Chronic low-grade inflammation is another key player in this cycle. Markers like elevated hs-CRP and interleukin-6 signal inflammation that worsens insulin resistance and amplifies PCOS symptoms. Abdominal fat contributes to this by releasing pro-inflammatory substances, such as TNF-α and interleukin-6, which further disrupt insulin signaling. Weight plays a significant role here: between 38% and 88% of women with PCOS are overweight or obese. Insulin resistance is found in 70–95% of obese cases, compared to 30–75% in lean cases. Encouragingly, even a modest weight loss of 5–10% can improve insulin sensitivity and lower androgen levels.
These interconnected challenges require a personalized approach. Oana Health offers telehealth solutions grounded in science, providing prescription-based treatments delivered straight to patients’ homes to help manage PCOS and insulin resistance effectively.
Different Types of PCOS and Insulin Resistance
PCOS comes in various forms, each influencing the severity of insulin resistance and shaping the best approach to treatment.
The 4 Types of PCOS
According to the Rotterdam criteria, PCOS is divided into four phenotypes:
- Phenotype A (O–H–P): This type includes all three hallmark features: irregular ovulation (oligo/anovulation), elevated androgen levels (hyperandrogenism), and polycystic ovaries visible on ultrasound. It's the most comprehensive form, affecting 51.9% of women with PCOS.
- Phenotype B (O–H): Characterized by irregular ovulation and high androgen levels, but without the polycystic ovary appearance. This classic metabolic form accounts for 23.1% of cases.
- Phenotype C (H–P): In this type, women experience elevated androgen levels and polycystic ovaries while maintaining regular ovulation. It represents 13.1% of cases.
- Phenotype D (O–P): This form involves irregular ovulation and polycystic ovaries but lacks elevated androgens. It accounts for 11.9% of diagnoses and is considered non-hyperandrogenic.
Insulin Resistance in Each PCOS Type
The severity of insulin resistance varies significantly among these phenotypes. A 2023 study examining 160 women with PCOS highlighted these differences:
| PCOS Phenotype | Key Features | Insulin Resistance Rate |
|---|---|---|
| Phenotype A | All three symptoms | 74.7% |
| Phenotype B | Irregular cycles + high androgens | 91.9% |
| Phenotype C | High androgens + polycystic ovaries | 57.1% |
| Phenotype D | Irregular cycles + polycystic ovaries | 57.9% |
Phenotype B stands out with the highest insulin resistance rate, reaching nearly 92%. Classic types (A and B) generally show more severe metabolic dysfunction than non-classic ones (C and D). Notably, these patterns occur regardless of weight, meaning even lean women with PCOS can face significant insulin resistance challenges.
How PCOS Type Affects Treatment
Understanding these phenotypes helps tailor treatment plans to individual needs. Women with phenotypes A and B face a higher risk of developing type 2 diabetes and cardiovascular issues due to their pronounced metabolic disturbances. They often see the most benefit from insulin-sensitizing medications like metformin, intensive lifestyle changes focused on weight management, and regular monitoring for metabolic complications.
Phenotype B patients, in particular, respond well to insulin-sensitizing treatments and lifestyle adjustments, showing marked improvements in metabolic health when these strategies are applied.
On the other hand, phenotypes C and D typically have milder symptoms and lower metabolic risks. Women with phenotype D may benefit less from insulin-targeted therapies and often require treatments focused on managing reproductive symptoms.
This phenotype-based approach allows for more personalized care, addressing both reproductive and metabolic health. For those seeking convenient, tailored PCOS management, Oana Health offers science-backed, prescription-based treatments delivered directly to patients' homes, providing comprehensive support for both insulin resistance and hormonal concerns.

Symptoms and Health Risks of PCOS with Insulin Resistance
When PCOS and insulin resistance occur together, the combination can intensify symptoms and increase long-term health risks. Identifying these signs early is key to managing the condition effectively.
Common Symptoms Linked to Insulin Resistance
For women with PCOS, high insulin levels can push the ovaries to produce more androgens, or male hormones. This hormonal imbalance can lead to several challenging symptoms:
- Excess abdominal fat, making weight management more difficult.
- Hirsutism, or unwanted hair growth, along with persistent acne and oily skin.
- Scalp hair thinning or hair loss, even as hair grows in other areas.
- Irregular menstrual cycles, caused by disrupted ovulation.
- Acanthosis nigricans, which appears as dark, velvety patches of skin on areas like the neck, armpits, or groin - often a sign of metabolic changes.
While women with obesity and PCOS often experience more severe insulin resistance and symptoms, lean women can also be affected, though their symptoms may be less intense.
These symptoms not only disrupt daily life but also point to deeper health concerns.
Long-Term Health Risks: Diabetes and Cardiovascular Issues
The combination of PCOS and insulin resistance significantly raises long-term health risks. Women with both conditions face a four- to sevenfold higher likelihood of developing type 2 diabetes. If left unmanaged, insulin resistance can progress to impaired glucose tolerance and eventually diabetes.
Additionally, metabolic syndrome - characterized by high blood pressure, abnormal cholesterol levels, central obesity, and elevated blood sugar - further increases the risk of heart disease. Studies have linked higher insulin resistance to elevated blood pressure, increased triglycerides, and a greater free androgen index. Chronic low-grade inflammation, often present in these cases, adds to the metabolic strain.
Early detection and intervention are crucial. Regular screenings for glucose intolerance, lipid imbalances, and high blood pressure can help catch these risks before they escalate. Lifestyle changes and medications like insulin sensitizers can slow the progression to diabetes and reduce cardiovascular risks.
Margaret K., a patient of Oana Health, shared her experience:
"Thanks to Oana, my menstrual cycles are more regular, and my skin has never looked better!"
Telehealth platforms like Oana Health provide science-backed treatments that target both insulin resistance and hormonal imbalances. Options such as prescription Metformin ER start at $22 per month, offering accessible support for women managing PCOS and its related metabolic challenges.
Treatment Options for PCOS and Insulin Resistance
Managing PCOS alongside insulin resistance involves a combination of medications, lifestyle adjustments, and accessible care options. By understanding the different PCOS phenotypes and how they correlate with varying levels of insulin resistance, tailored treatment plans can help alleviate symptoms and lower the risk of long-term complications.
Medications for Insulin Resistance
Metformin is widely regarded as the go-to medication for managing insulin resistance in women with PCOS. It works by enhancing insulin sensitivity and reducing glucose production in the liver. Research indicates that Metformin can lower fasting insulin levels and improve ovulation rates in women with PCOS. It is particularly effective for those experiencing metabolic issues or high levels of insulin resistance.
However, Metformin can cause gastrointestinal side effects such as nausea, diarrhea, and abdominal discomfort. For women who experience these issues, topical Metformin offers an alternative. This formulation boosts insulin sensitivity without the gastrointestinal side effects, making it easier for patients to stick to their treatment plan.
Another option is GLP-1 receptor agonists, such as liraglutide and semaglutide. These newer medications are highly effective for weight loss and improving insulin sensitivity. Clinical trials have shown that women with PCOS using GLP-1 agonists can achieve an average weight loss of 5-10% of their body weight within 6-12 months. These medications are especially beneficial for overweight or obese women, as they simultaneously address weight and insulin resistance.
The choice of medication often depends on the PCOS phenotype. Women with classic phenotypes (A & B), who tend to have higher levels of insulin resistance, may benefit more from GLP-1 agonists. Metformin, however, remains a popular first-line treatment for a broader range of PCOS cases. Research highlights that women with phenotype B PCOS experience the highest rates of insulin resistance - up to 91.9% in some studies - making insulin-sensitizing medications a critical part of their care.
| Medication | How It Works | Best For | Common Side Effects | Monthly Cost |
|---|---|---|---|---|
| Metformin | Enhances insulin sensitivity | Most PCOS types | Nausea, diarrhea | $22 |
| Topical Metformin | Improves insulin sensitivity without GI issues | Sensitive to oral Metformin | Mild skin irritation | $89 |
| GLP-1 Agonists | Promotes weight loss and improves insulin use | Overweight/obese PCOS | Nausea, vomiting | $199 |
Lifestyle changes can further amplify the benefits of these medications.
Diet and Exercise Adjustments
Lifestyle modifications are a cornerstone of managing PCOS and insulin resistance. Even a modest weight loss of 5-10% can significantly enhance insulin sensitivity, lower androgen levels, and restore ovulation cycles. The focus should be on consistency rather than striving for perfection.
Dietary changes play a crucial role. Low-glycemic index diets, Mediterranean-style eating, and high-protein meal plans have been shown to improve insulin sensitivity and alleviate PCOS symptoms. These diets emphasize foods that prevent rapid spikes in blood sugar, such as whole grains, vegetables, lean proteins, and healthy fats.
Exercise is equally important. A combination of aerobic activities - like walking, cycling, or swimming - and resistance training is particularly effective. Aerobic exercise improves cardiovascular health and insulin sensitivity, while resistance training builds muscle, which helps the body manage glucose better.
A 2022 study published in Frontiers in Public Health highlighted the benefits of combining approaches. Women with PCOS who combined Metformin with diet and exercise saw a 30% greater reduction in HOMA-IR (a marker of insulin resistance) over six months compared to those relying on Metformin alone.
Beyond medications and lifestyle changes, telehealth services are making PCOS care more accessible and personalized.

Key Points About PCOS and Insulin Resistance
The connection between PCOS and insulin resistance is intricate and impacts many aspects of health. Insulin resistance is a frequent issue for women with PCOS, affecting a large portion of them, including those who are lean but still face significant metabolic challenges.
Studies indicate that classic PCOS phenotypes (A and B) are associated with higher levels of insulin resistance, which plays an essential role in tailoring treatment strategies. Understanding your specific PCOS type can help anticipate metabolic risks and create a more customized treatment plan.
The effects of insulin resistance extend beyond blood sugar regulation. It exacerbates several PCOS symptoms, such as irregular menstrual cycles, excessive hair growth on the face and body, acne, and weight gain. Elevated insulin levels can stimulate the ovaries to produce more androgens, which can intensify these symptoms over time.
Inflammation is another key factor in this relationship. Women with PCOS and insulin resistance often show increased levels of inflammatory markers like C-reactive protein and interleukin-18, which can worsen both metabolic and reproductive health challenges.
Insulin resistance in PCOS is also linked to a higher risk of developing type 2 diabetes and cardiovascular disease. Research suggests that women with PCOS may experience a 27% reduction in insulin sensitivity compared to those without the condition, though this gap can be narrowed with the right interventions. Addressing these risks through targeted treatments is essential.
Medications and lifestyle changes aimed at reducing insulin resistance can significantly improve PCOS symptoms. Treatments include options like metformin, GLP-1 agonists, and tailored lifestyle adjustments. Thanks to advancements in telehealth, platforms like Oana Health now make these evidence-based approaches more accessible, offering personalized care from the comfort of home.
Given the importance of early intervention, all women with PCOS should be screened for insulin resistance. Identifying and treating insulin resistance early can help prevent severe health complications and improve overall well-being.
