What PCOS Treatment Aims to Do
Treating PCOS means tackling the root causes of the condition, not just masking its symptoms. Since PCOS is a long-term metabolic condition, any effective approach must address the interconnected challenges it presents, rather than focusing on isolated issues.
The main goals of treatment revolve around three key areas: improving insulin sensitivity, regulating menstrual cycles, and managing high androgen levels. These areas are closely linked, as PCOS affects both reproductive and metabolic health. Success often depends on tailoring treatments to each individual’s specific symptoms. By targeting these objectives, treatment helps restore hormonal and metabolic balance, addressing both the visible symptoms and the underlying causes.
Treating Insulin Resistance
Insulin resistance is a major driver of PCOS symptoms, as high insulin levels fuel excessive androgen production. This issue affects about 70% of women with PCOS. Tackling insulin resistance can lead to significant improvements. For instance, studies show that losing just 5% of body weight can improve ovarian function, potentially restore fertility, and reduce the risk of conditions like type 2 diabetes and heart disease.
Regulating Hormones and Menstrual Cycles
Imbalances in insulin also disrupt hormone levels, making it essential to restore regular menstrual cycles. PCOS is often characterized by elevated male hormone levels, which interfere with ovulation and menstrual patterns. Treatment focuses on rebalancing hormones to support regular ovulation. High androgen levels can prevent proper egg development and release, leading to irregular or missed periods and low progesterone levels. By reducing androgen production and promoting healthy ovarian function, treatments aim to reestablish a natural hormonal rhythm.
Managing Other Symptoms of PCOS
PCOS treatment also addresses symptoms that can significantly impact daily life, such as excessive hair growth, acne, and weight gain. These issues stem from the same hormonal imbalances driving the condition. As treatments improve insulin sensitivity and lower androgen levels, many women notice improvements in energy, mood, skin clarity, and overall well-being. Since 40–80% of women with PCOS are affected by obesity, managing weight becomes a key part of symptom control, as it helps address the underlying metabolic challenges. Lifestyle changes, like diet and exercise, often complement medical treatments to enhance symptom relief.
How Metformin and Birth Control Work
To understand why Metformin and birth control address different aspects of PCOS, it’s helpful to look at how each treatment works. Metformin targets metabolic issues, while birth control focuses on balancing hormones. Here’s a closer look at how they tackle PCOS from different angles.
How Metformin Works
Metformin is commonly used to treat insulin resistance, a condition affecting 50%-70% of women with PCOS. It’s an oral medication that helps the body respond better to insulin by working at the cellular level. Metformin primarily reduces glucose production in the liver and improves how peripheral tissues respond to insulin. It also activates AMPK, a cellular enzyme that enhances glucose uptake.
The results? Fasting insulin levels can drop by about 40%, and many women experience an average weight loss of around 5.8%. Beyond these metabolic improvements, Metformin helps lower androgen levels in the bloodstream. As insulin levels stabilize, many women notice more regular menstrual cycles and even improved fertility.
How Birth Control Works
Birth control pills take a different approach, focusing on hormone regulation rather than insulin resistance. These pills contain synthetic versions of estrogen and progestin, which influence the body’s natural hormone production. By suppressing ovarian function, birth control reduces androgen production.
With a steady dose of hormones followed by a hormone-free interval, birth control pills help create predictable menstrual cycles. While they’re effective for managing hormonal symptoms, it’s important to note that they don’t address insulin resistance. Instead, their role is centered on controlling the hormonal imbalances linked to PCOS.
Which Treatment Works Better for Different Symptoms
Managing PCOS effectively means matching the treatment to your most prominent symptoms. Here's a breakdown to help you understand which options work best for specific concerns.
What Metformin Excels At
Metformin shines when it comes to tackling the metabolic aspects of PCOS. For instance, a study involving 150 obese women showed a 10% reduction in BMI after using metformin. Additionally, a long-term study of 23 women with PCOS found that nearly half resumed regular menstruation, with over 90% achieving consistent cycles after at least six months of treatment.
What Birth Control Excels At
Birth control pills are particularly effective at addressing hormonal imbalances and cosmetic symptoms. They can quickly regulate menstrual cycles - research highlights that combined oral contraceptives are especially effective for this purpose. Pills containing both estrogen and progestin also lower male hormone levels, which helps reduce acne, excessive facial and body hair, and male-pattern baldness. Interestingly, studies suggest that metformin may not be as effective for treating hirsutism, especially in women with a BMI between 25 and 30 kg/m². Moreover, oral contraceptives offer additional benefits, such as reducing the risk of ovarian and endometrial cancers by nearly 30%.
Choosing the Right Option for You
Your dominant symptoms and health priorities will guide your choice of treatment.
Metformin may be the right fit if you have:
- Insulin resistance or pre-diabetes
- Significant challenges with weight management
- Plans to conceive in the near future
- Primarily metabolic symptoms
Birth control might be better suited if you experience:
- Severe irregular periods or heavy bleeding
- Persistent acne or excessive hair growth
- No immediate plans for pregnancy
- Mainly hormonal symptoms
Clinical guidelines often recommend combined oral contraceptives for irregular cycles and hirsutism, while metformin is preferred for metabolic concerns. Women with higher BMIs tend to see better metabolic improvements with metformin, whereas those with normal weight might benefit from either treatment depending on their symptoms. In some cases, combining both treatments can address multiple aspects of PCOS at the same time. Up next, take a closer look at possible side effects to finalize your decision.

Side Effects and Things to Consider
Knowing the potential side effects of treatments is an important part of managing PCOS effectively. It helps you prepare for what to expect and allows for more informed conversations with your healthcare provider.
Metformin Side Effects
Metformin is widely used for PCOS, but it often causes gastrointestinal discomfort in about 50% of patients. Common issues include heartburn, stomach pain, nausea, vomiting, bloating, gas, diarrhea, and constipation. Other complaints might include headaches, a metallic taste, or even mild weight loss.
The good news? These symptoms usually improve with dose adjustments. Starting with a low dose and taking the medication with meals can help. Extended-release versions of metformin are another option for reducing these side effects.
On rare occasions, metformin may lead to a serious condition called lactic acidosis, especially in those with kidney problems or heavy alcohol use. To prevent this, your doctor will monitor your kidney function regularly.
Birth Control Side Effects
Birth control pills, another common treatment for PCOS, are known to cause spotting, nausea, headaches, mood changes, breast tenderness, and weight changes. Fortunately, these effects typically subside within the first few months.
However, the most concerning risk is an increased chance of blood clots. Oral contraceptives can raise the relative risk of venous thromboembolism (VTE) by three- to six-fold. For context, the risk increases from about 5 cases per 10,000 women in non-users to 9–10 cases per 10,000 women in users. Women with PCOS face an even higher risk - about 1.5 to 2 times greater than those without PCOS. If you have a family history of blood clots or clotting disorders, it's essential to share this information with your healthcare provider before starting birth control.
Long-Term Use Considerations
Metformin is generally safe for long-term use, but it can sometimes lead to a vitamin B12 deficiency. This deficiency might result in anemia or nerve-related issues. Regular monitoring of B12 levels and taking supplements, if necessary, can address this. Interestingly, some studies suggest that metformin might lower the risk of cancer and dementia in people with diabetes.
For birth control pills, the blood clot risk does not diminish over time, and certain types of progestins - like desogestrel, drospirenone, and gestodene - carry higher risks compared to levonorgestrel. Regular evaluations of cardiovascular risk factors are crucial. Long-term use may also impact blood pressure, glucose metabolism, and cholesterol levels, making lifestyle changes an essential part of treatment.
Lifestyle plays a big role in managing PCOS over the long term. Losing just 5% of your body weight can significantly improve symptoms and boost the effectiveness of medications. Weight loss, combined with a healthy diet and regular exercise, can lower insulin and testosterone levels, sometimes even leading to more regular menstrual cycles. If you're taking birth control and have a higher BMI, working with a registered dietitian can help reduce potential metabolic side effects and improve overall outcomes.
How to Choose the Right Treatment
Deciding between metformin and birth control for managing PCOS isn't a one-size-fits-all process. The best choice depends on your specific symptoms, medical history, and personal goals.
Working with Your Doctor
PCOS presents itself differently in every individual, so treatment needs to be tailored. Start by discussing your medical history with your doctor, especially if you have risk factors like smoking, high blood pressure, diabetes, or blood clotting disorders.
Your reproductive goals play a big role too. If you're looking to conceive soon, metformin might be the better option. On the other hand, if you need contraception or want to regulate your cycle, birth control could be more suitable. These considerations will help guide the treatment decision.
Practical factors also matter. For instance, think about the cost, how convenient the treatment is, and how well you tolerate side effects. Birth control pills require daily use, while metformin is usually taken with meals to reduce stomach upset. Some people find one routine easier to maintain than the other.
Your BMI and overall metabolic health are crucial as well. If your main concerns are irregular periods and unwanted hair growth, birth control might address these better. But if insulin resistance and metabolic issues are at the forefront, metformin could be the right starting point.
These discussions with your doctor can also help you explore whether a single treatment or a combination approach might work best.
Using Both Treatments Together
Once you've evaluated your individual needs, you might consider combining treatments. Research suggests that using both metformin and oral contraceptives together can be more effective than birth control alone, particularly for individuals without obesity.
For example, a 2011 study followed 19 overweight women with PCOS over three months. The group using both metformin and birth control experienced a 1.9% reduction in BMI and a 69% improvement in flow-mediated dilation (a measure of blood vessel health). In contrast, the group taking only birth control did not see these benefits. Birth control is effective for managing hormonal symptoms like irregular periods and excess hair growth, while metformin targets insulin resistance, which affects over 75% of people with PCOS. Together, they can address both the hormonal and metabolic challenges of the condition.
However, while combination therapy may offer broader benefits, it can also increase the risk of side effects and raise costs. It's important to discuss these potential drawbacks with your doctor. Some people start with one treatment and add the other later if needed.
Ultimately, the choice depends on your unique symptoms and priorities. If you're dealing with both metabolic and hormonal issues, exploring combination therapy with your healthcare provider could help you manage PCOS more effectively.
Keep in mind that treatment plans are highly individualized. What works well for one person may not be the best fit for you, and that's completely normal. Open communication with your doctor is key to finding the most effective approach for your situation.
Key Points to Remember
When deciding between metformin and birth control for managing PCOS, it’s important to understand what each medication is designed to address. Birth control pills are particularly effective for hormonal symptoms like irregular periods and excess hair growth. On the other hand, metformin focuses on metabolic issues, such as insulin resistance, which affects an estimated 50%–70% of women with PCOS.
Medical guidelines generally recommend birth control for issues like irregular cycles and hirsutism, while metformin is suggested for managing metabolic challenges. So, if your primary concerns are unpredictable periods or unwanted hair growth, birth control might be the better option. However, if insulin resistance or high cholesterol are your main struggles, metformin could be more effective. In some cases, a combination of both treatments might offer the most comprehensive relief.
It’s important to note that neither treatment is inherently better than the other - they simply target different aspects of PCOS. Birth control helps regulate hormones, while metformin improves the body’s sensitivity to insulin. Depending on your symptoms, a tailored approach that combines both treatments might work best.
Ultimately, your symptoms and personal health goals should guide your treatment choice. Partnering with a knowledgeable healthcare provider is crucial. They can assess your medical history, symptoms, and reproductive goals to create a plan that works for you.
Research also suggests that combination therapy - using both metformin and birth control - can be particularly effective for managing hirsutism. This strategy may provide more well-rounded benefits than relying on a single treatment.
PCOS affects about 8% to 18% of women of reproductive age, and treatment plans should be as personalized as the condition itself. Regular communication with your healthcare provider is essential for managing symptoms and improving overall well-being.
