Top Treatments for Insulin Resistance and Thyroid in PCOS

Polycystic Ovary Syndrome (PCOS) is a common hormonal condition affecting up to 15% of women of reproductive age. It’s strongly linked to insulin resistance (70% of cases) and thyroid dysfunction, which can worsen symptoms like irregular periods, infertility, and metabolic issues. Here’s a breakdown of the most effective treatments:

• Metformin: Improves insulin sensitivity, regulates blood sugar, and supports menstrual regularity. Costs about $3/month.
• Levothyroxine: Addresses thyroid hormone imbalances, aiding metabolism and ovulation. Costs range from $12–$270/month.
• Spironolactone: Reduces androgen-related symptoms like acne and unwanted hair. Costs around $14/month.
• GLP-1 Receptor Agonists: For advanced insulin resistance, these medications improve glucose control and assist with weight loss. Costs can exceed $1,000/month without insurance.
• Lifestyle Adjustments: Diet, exercise, and weight management significantly improve symptoms and insulin sensitivity. Affordable and effective.
• Combination Therapies: Pairing treatments like metformin with spironolactone or GLP-1 agonists offers broader symptom relief.

Quick Comparison

Metformin for PCOS (what it does & natural treatment options)

1. Metformin for Insulin Resistance

Metformin is widely regarded as the go-to medication for improving insulin function in women with PCOS. This biguanide works by decreasing glucose production in the liver and enhancing the body's ability to absorb glucose in the liver and skeletal muscles. Women with PCOS often have normal insulin molecules and receptors but face a post-receptor defect that leads to insulin resistance within their cells. Metformin also activates the AMPK pathway, which helps transport glucose into muscle cells.

The effects are impressive: fasting serum insulin levels can drop by roughly 40%, and plasma glucose levels often fall to around 72–81 mg/dL (4–4.5 mM). For those with diabetes, metformin typically lowers HbA1c levels by 1.5–2.0%. These biochemical improvements often lead to better menstrual cycle regularity and enhanced fertility.

Impact on PCOS-Related Symptoms

Metformin offers a range of benefits for managing PCOS symptoms. It helps regulate menstrual cycles, encourages ovulation, and lowers androgen levels. Additionally, it supports mild weight loss and can curb sugar cravings. A 2020 meta-analysis of 21 clinical trials found that metformin had a small but meaningful effect on reducing BMI, particularly in individuals with obesity. One study even reported an average weight loss of 13 to 15 pounds.

"PCOS is a complex metabolic condition that affects multiple body systems, making it challenging to treat."

• Jessica Shepherd, MD, board-certified OB/GYN and Chief Medical Officer of Hers

For women struggling with infertility, metformin can be a game-changer. By improving the body's insulin response and reducing glucose production in the liver, it helps restore regular menstrual cycles and boosts fertility. This is especially critical since PCOS is a leading cause of infertility.

Ease of Integration into Daily Life

Metformin is easy to incorporate into daily routines. It’s taken orally, typically starting with a dose of 500 mg once a day, with gradual increases as needed. To minimize common gastrointestinal side effects, it’s best taken with food. Pairing metformin with healthy lifestyle choices - like eating a balanced diet, exercising regularly, staying hydrated, and getting enough sleep - can amplify its benefits.

Its straightforward oral dosing and affordability make it a practical solution for many women in the U.S.

Cost and Accessibility for Patients in the United States

Metformin is both affordable and widely available in its generic form. In the U.S., a one-month supply of generic metformin costs about $3. This low cost ensures that most women can access this vital treatment for managing PCOS-related insulin resistance without significant financial strain.

2. Levothyroxine for Thyroid Management

Levothyroxine, a synthetic form of the T4 hormone, is commonly prescribed to treat hypothyroidism - a condition that women with PCOS are 2.5 times more likely to experience compared to the general population. By supplementing or replacing the body's deficient thyroid hormone production, levothyroxine helps restore normal metabolic processes.

Effectiveness in Addressing Thyroid Dysfunction

Levothyroxine works by providing T4, which the body converts into the active hormone T3 in various tissues. This process helps improve metabolic markers. Studies reveal that women with both PCOS and subclinical hypothyroidism often have higher triglyceride levels, elevated fasting insulin, and increased HOMA-IR (a measure of insulin resistance) compared to those with normal thyroid function. By normalizing thyroid hormone levels, levothyroxine can lead to improvements in these markers, supporting better overall metabolic health.

Impact on PCOS-Related Symptoms

Thyroid hormones play a critical role in reproductive health, influencing ovarian function, egg development, and the quality of the uterine lining. Improved thyroid function can promote regular ovulation and aid in weight management - two challenges commonly faced by women with PCOS. Additionally, untreated subclinical hypothyroidism is linked to a 90% higher risk of miscarriage compared to women with normal thyroid function. Addressing thyroid imbalances is an essential part of managing PCOS, especially when combined with treatments targeting insulin resistance.

Ease of Integration into Daily Life

Taking levothyroxine is straightforward. It’s typically prescribed as a once-daily oral tablet that should be taken on an empty stomach, at least 30–60 minutes before breakfast. Keeping the medication in a convenient location can help maintain a consistent routine. Regular blood tests - initially every 6 to 8 weeks and later every 6 to 12 months once levels stabilize - allow healthcare providers to adjust the dosage as needed. Its simple dosing schedule makes it easy to incorporate into a broader PCOS treatment plan.

Cost and Accessibility for Patients in the United States

In the U.S., generic levothyroxine costs range from about $12 to $270 per month, depending on the dosage and pharmacy. Discount programs like GoodRx can help lower these costs. Additionally, most Medicare and insurance plans cover generic levothyroxine with minimal copays, ensuring that treatment remains accessible. Affordable thyroid management, when paired with other targeted therapies, plays a crucial role in addressing the complex needs of women managing PCOS.

3. Spironolactone for Androgen Reduction

When it comes to addressing the hormonal imbalances of PCOS, spironolactone plays a critical role in reducing the effects of hyperandrogenism, a condition that affects about 80% of women with PCOS. Hyperandrogenism is marked by an overproduction of male hormones, leading to issues like acne, unwanted facial or body hair, and hair thinning or loss in a male-pattern distribution. Originally developed as a potassium-sparing diuretic, spironolactone has become a go-to option for managing these androgen-related symptoms in PCOS.

Spironolactone works by lowering testosterone levels and speeding up its breakdown in the body. Unlike treatments that primarily address insulin resistance or thyroid issues, spironolactone directly targets the hormonal disruptions that cause many of the visible and often distressing symptoms of PCOS. This makes it a valuable complement to other therapies, such as those focused on insulin or thyroid regulation.

Impact on PCOS-Related Symptoms

Spironolactone is particularly effective at reducing symptoms like acne, hirsutism (excess facial and body hair), irregular periods, and hair loss. Improvements in acne can often be seen within three months, while other symptoms, like hair growth and hair loss, may take three to six months to show noticeable changes. However, patience is key, as full results may take up to six months.

It’s important to note that spironolactone is not safe during pregnancy or breastfeeding due to potential risks. For sexually active women, using spironolactone alongside reliable birth control is recommended to ensure safety.

Ease of Integration into Daily Life

Spironolactone is taken orally, typically once or twice a day with food to help reduce nausea. Common side effects include dizziness, muscle cramps, fatigue, and breast tenderness or enlargement. To minimize dizziness, it helps to stand up slowly from sitting or lying down.

Dietary adjustments are also necessary while taking this medication. Patients should avoid salt substitutes containing potassium and limit high-potassium foods like bananas and avocados. Regular monitoring of electrolytes is crucial, as hyperkalemia (high potassium levels) has been reported in about 16.1% of cases.

Spironolactone may also cause changes in menstrual cycles, including irregular or missed periods and breakthrough bleeding. Women experiencing severe side effects should consult their doctor. Additionally, activities like driving or operating machinery should be avoided if drowsiness occurs.

Cost and Accessibility for Patients in the United States

Spironolactone is widely available as a generic medication, making it an affordable treatment option for many women with PCOS. It’s often prescribed off-label to manage symptoms related to high androgen levels. Insurance coverage is typically good since spironolactone is a well-established medication with multiple FDA-approved uses. Most users experience only mild or temporary side effects, making it a practical choice for long-term management of androgen-related symptoms. When combined with therapies for insulin resistance or thyroid dysfunction, spironolactone offers a comprehensive approach to managing PCOS.

4. GLP-1 Receptor Agonists for Advanced Insulin Resistance

GLP-1 receptor agonists are a promising option for PCOS patients who don’t respond well to metformin. These medications help improve insulin release in a glucose-dependent way, which means they reduce the risk of hypoglycemia. Since managing insulin sensitivity is a cornerstone of PCOS treatment, these drugs play an important role for patients with more resistant cases of insulin resistance. They represent a newer tool in addressing the metabolic challenges associated with PCOS.

Effectiveness in Addressing Insulin Resistance

GLP-1 receptor agonists work on multiple fronts to combat insulin resistance. They improve glucose transporter expression, reduce inflammation, and lower oxidative stress. These actions, combined with their ability to regulate lipid metabolism, help decrease fasting insulin levels, 2-hour glucose levels from oral glucose tolerance tests, and HOMA-IR scores. Additionally, these medications aid in weight loss by enhancing insulin production, suppressing glucagon secretion, slowing gastric emptying, and increasing feelings of fullness.

Impact on PCOS-Related Symptoms

Beyond their metabolic benefits, GLP-1 receptor agonists can also help alleviate a range of PCOS-related symptoms. Research has shown that liraglutide, for example, significantly reduces BMI, liver fat, and visceral fat. It also lowers free testosterone levels, which can help regulate menstrual cycles and reduce symptoms like acne and excess hair growth (hirsutism). A case-control study by Kahal et al. highlighted additional improvements in body weight and quality of life, including better social, physical, and psychological well-being. These benefits make GLP-1 receptor agonists a valuable addition to broader PCOS management strategies.

Ease of Integration into Daily Life

These medications are available as daily or once-weekly injections, offering flexibility and effective glucose control with fewer gastrointestinal side effects. It’s important to screen patients for contraindications and schedule regular follow-ups to fine-tune their treatment plans.

Cost and Accessibility in the United States

One major challenge with GLP-1 receptor agonists is their cost. Without insurance, they can run about $1,000 per month. While discount programs and initiatives from manufacturers can help reduce expenses, the high price limits their use to fewer than 3% of eligible patients in the U.S..

For women with PCOS who haven’t had success with other treatments for insulin resistance, GLP-1 receptor agonists offer a way to address multiple metabolic issues. Although the cost is a significant hurdle, the potential improvements in metabolic health, weight management, and overall quality of life make these medications worth considering for advanced PCOS care.

5. Diet, Exercise, and Weight Management

Making changes to your diet, staying active, and managing weight are key steps in addressing PCOS symptoms. These lifestyle adjustments can improve insulin sensitivity and help balance hormones, offering meaningful relief.

Effectiveness in Addressing Insulin Resistance

Your diet plays a big role in managing insulin sensitivity. Studies show that women with PCOS often eat less fiber than those without the condition, and this lower fiber intake is linked to higher insulin resistance. In fact, fiber intake combined with BMI accounts for 54% of the differences in insulin resistance scores. Foods like cruciferous vegetables, beans, lentils, almonds, and berries are great options because they slow digestion and help keep blood sugar stable. Cutting back on refined carbs can also reduce inflammation.

Exercise is another powerful tool for improving insulin action, especially when done regularly - daily or at least every other day. A mix of cardio and strength training works well, with high-intensity interval training (HIIT) showing particular promise for reducing insulin resistance and abdominal fat. Research suggests that committing to at least 120 minutes of vigorous exercise each week can lead to better metabolic health.

Managing weight further enhances these benefits. Losing just 5% of your body weight can improve insulin resistance, hormone levels, menstrual cycles, and even fertility. A meta-analysis of 19 trials involving 1,193 participants found that dietary changes were more effective than exercise or metformin in improving both metabolic and reproductive health in women with PCOS. These improvements often lead to better overall symptom management.

Impact on PCOS-Related Symptoms

Lifestyle changes don’t just help with metabolism - they can also significantly ease PCOS symptoms. For example, a study by Marsh et al. found that women with PCOS following a low glycemic index (GI) diet saw a threefold improvement in insulin sensitivity compared to those on a standard healthy diet. Additionally, 95% of the low-GI group achieved regular menstrual cycles and ovulation, compared to 63% in the control group.

Contrary to earlier beliefs, research now indicates that women with PCOS can lose weight at similar rates to those without the condition. Higher fiber intake has been linked to lower insulin resistance, reduced total body fat, and less abdominal fat. Diets that prioritize protein may also support weight loss.

Staying active doesn’t just help with weight - it lowers the risk of heart disease and stroke by up to 35%.

Ease of Integration into Daily Life

Incorporating these lifestyle changes into your routine can be simpler than it seems. For dietary adjustments, start small. Swap refined bread for whole-grain, high-fiber options, and skip sugary drinks. Focus on whole foods that are rich in protein and healthy fats to stabilize blood sugar and make meals more satisfying.

Exercise doesn’t have to be complicated. Aim for about 150 minutes of physical activity per week - that’s just 20 minutes a day. You can mix strength training, cardio, and stress-relieving activities like yoga. If you’re new to working out, low-impact options like swimming, cycling, or even Tai Chi can be great starting points.

For weight management, sustainable habits are key. Prioritize 7 hours of sleep, practice mindfulness to manage stress, and focus on nutrient-dense foods to support your overall health.

Cost and Accessibility for Patients in the United States

Lifestyle changes are some of the most affordable ways to manage PCOS. Many dietary adjustments, like choosing whole foods, and exercise options, such as walking or home workouts, require little to no cost. These changes can also reduce the need for medications and frequent doctor visits, saving money in the long run.

Additionally, telehealth services like Oana Health offer personalized plans that combine lifestyle changes with medical guidance, making it easier to get the support you need without breaking the bank.

6. Combination Treatments: Metformin & Spironolactone or GLP-1 & Metformin

When it comes to managing PCOS, combining treatments can tackle multiple aspects of the condition at once, providing more comprehensive relief. Two combinations that have shown promise are metformin with spironolactone and metformin with GLP-1 receptor agonists. These pairings work on different fronts, offering benefits that often surpass those of single treatments.

Effectiveness in Addressing Insulin Resistance

The combination of GLP-1 receptor agonists and metformin has been particularly effective in addressing insulin resistance and related issues. A meta-analysis involving 337 participants revealed that this pairing led to significant improvements: an average weight loss of 3.02 lbs, a BMI reduction of 0.88 kg/m², a 2.46 cm decrease in waist circumference, and lower fasting and post-meal glucose levels by 0.30 and 1.58 units, respectively.

On the other hand, the metformin and spironolactone combination takes a complementary approach. While metformin directly targets insulin resistance, spironolactone reduces androgen levels, which can indirectly improve insulin sensitivity. Studies have shown that using these two medications together is more effective in reducing BMI and androgen levels compared to using either one alone.

Impact on PCOS-Related Symptoms

These combinations don’t just improve insulin resistance - they also address other troublesome PCOS symptoms. For example, the GLP-1 and metformin regimen has been shown to increase sex hormone-binding globulin (SHBG) by about 10.04 points compared to metformin alone. Higher SHBG levels can help counteract the effects of excess androgens, alleviating symptoms like acne and unwanted facial hair.

Patient feedback further highlights the benefits of these treatments. Testimonials from Oana Health users report improvements in menstrual regularity, clearer skin, and reduced excess hair. Research backs these experiences, showing that combining metformin with low-dose spironolactone can not only ease symptoms more effectively but also improve adherence to the treatment plan.

Ease of Integration into Daily Life

Both combinations are relatively easy to incorporate into daily routines. The metformin and spironolactone regimen is taken orally, typically once or twice a day with meals, which can help reduce stomach upset. In contrast, GLP-1 receptor agonists are administered as weekly injections, offering convenience but requiring patients to manage potential side effects like nausea, vomiting, and dizziness, especially during the initial stages of treatment. Starting with a low dose and gradually increasing it can help minimize these side effects.

Cost and Accessibility for Patients in the United States

One of the biggest differences between these two options is cost. The metformin and spironolactone combination, available through Oana Health, is priced at just $32 per month. Both medications are available as generics, making this an affordable choice for many patients.

GLP-1 receptor agonists, however, come with a much steeper price tag - typically ranging from $700 to $800 per month in the U.S.. Dr. Jennifer Hwang from UChicago Medicine explains:

"While effective, GLP-1 receptor agonists cost approximately $700–$800 per month."

This high cost has sparked discussions about accessibility. Dr. David Kim from UChicago shares:

"We want people who need these medications to be able to access them. But to do that, we need lower prices, thoughtful coverage policies, and a clearer understanding of who benefits most."

There is some hope on the horizon. Semaglutide, a popular GLP-1 medication, is one of the first 15 drugs selected for Medicare price negotiations under the Inflation Reduction Act, with potential price adjustments expected in 2027. Historically, such negotiations have led to price reductions of about 20%.

For now, many patients find the metformin and spironolactone combination to be the most practical option, especially when offered through telehealth services like Oana Health. Its affordability and effectiveness make it a logical starting point for managing PCOS, especially for those concerned about costs.

Treatment Comparison Table

Here’s a quick guide to compare treatment options for managing PCOS-related insulin resistance and thyroid issues. The table highlights the key benefits, common side effects, dosage ranges, and monthly costs for each option.

Combination therapies provide a more tailored approach to managing symptoms. For example, pairing metformin with spironolactone can improve hormone regulation, while combining GLP-1 receptor agonists with metformin offers both insulin control and weight management benefits. However, treatments like spironolactone require regular blood tests to monitor electrolytes and liver function.

One important factor to consider is insurance coverage. GLP-1 receptor agonists, while effective, often lack consistent insurance approval for PCOS since they aren't officially indicated for this condition. To help with affordability, services like Oana Health partner with telemedicine providers and compounding pharmacies to offer competitive pricing, making these treatments more accessible across the U.S.

This comparison can help you weigh the effectiveness, potential side effects, and costs to find the best treatment plan for your needs.

Conclusion

Effectively managing PCOS means tackling both insulin resistance and thyroid dysfunction, as these two often work hand in hand to amplify symptoms. Consider this: more than half of women with PCOS develop type 2 diabetes by age 40, and Hashimoto's thyroiditis affects 22.8% of women with PCOS compared to only 5.7% in those without it. These numbers underscore the importance of a well-rounded approach to care.

Focusing on just one issue isn’t enough. Women dealing with both PCOS and thyroid problems often face heightened triglyceride levels, increased fasting insulin, and more severe metabolic challenges. To combat this, regular thyroid testing and a thorough hormone evaluation are key starting points. From there, addressing root causes through personalized nutrition, quality sleep, stress management, and consistent exercise becomes essential. With insulin resistance affecting anywhere from 50% to 75% of individuals with PCOS, managing blood sugar is a cornerstone of any effective treatment plan.

Personalized care can truly make a difference. Services like Oana Health offer science-backed, affordable treatment options, including combination therapies and topical metformin. Many patients have seen real progress. One patient shared:

"It's been a little over 5 weeks, and I've noticed a dramatic reduction in my facial hair growth. This has been such a relief for me. You really have to stick with it and be patient to notice results!"

• Allison L., Hairless Hype

This kind of tailored approach can set the stage for better long-term health outcomes.

The key to success lies in working with providers who understand the complex relationship between PCOS, insulin resistance, and thyroid health. Whether you opt for traditional medications, newer topical treatments, or a combination of approaches, taking that first step toward better hormonal balance is crucial. With the right plan and consistent care, you can manage symptoms and reduce long-term risks effectively.

FAQs

What lifestyle changes can help manage insulin resistance and thyroid issues in women with PCOS?

Managing insulin resistance and thyroid issues in PCOS often starts with making smarter lifestyle choices. One key step is cutting back on sugars and refined carbs, as these can make insulin resistance worse. Instead, focus on including more anti-inflammatory foods in your meals - think leafy greens, nuts, fatty fish, and whole grains.

Staying active is equally important. Incorporate a mix of strength training and moderate aerobic exercises like walking or cycling into your routine. On top of that, addressing stress can work wonders for hormonal balance. Practices like meditation, yoga, or even talking with a therapist can help keep stress in check. Lastly, working toward a healthy weight - even with small, steady changes - can improve both insulin sensitivity and thyroid function over time.

How do combination treatments like Metformin with Spironolactone or GLP-1 receptor agonists with Metformin help manage PCOS symptoms more effectively?

Combination therapies, like pairing Metformin with Spironolactone or GLP-1 receptor agonists with Metformin, can be highly effective for managing PCOS symptoms. These approaches tackle multiple issues at once, addressing both metabolic and hormonal imbalances.

For instance, Metformin and Spironolactone work together to reduce insulin resistance, lower androgen levels, and aid in weight management. This dual action helps target the root causes of PCOS more effectively. Similarly, combining GLP-1 receptor agonists with Metformin can amplify weight loss, improve insulin sensitivity, and regulate blood sugar levels. This combination is particularly beneficial for women who are overweight or obese.

By addressing both metabolic dysfunction and hyperandrogenism, these treatment combinations provide broader relief compared to using single therapies.

What are the costs and accessibility challenges of using GLP-1 receptor agonists for treating insulin resistance in PCOS?

GLP-1 receptor agonists have proven to be an effective option for tackling advanced insulin resistance in PCOS. However, their steep price tags often put them out of reach for many. In the United States, the monthly out-of-pocket cost for these medications typically falls between $700 and $1,500, with an average hovering around $1,000 per month. Without insurance, these costs can be overwhelming.

Even with insurance, access isn’t always straightforward. Issues like prior authorization requirements and limited coverage under employer health plans can create additional hurdles. On top of that, the high demand for these medications, coupled with frequent discontinuation rates, makes long-term use especially challenging - particularly for underserved communities. This underscores the pressing need for treatment options that are both more affordable and easier to access for managing insulin resistance in PCOS.
