Understanding PCOS & Insulin Resistance
Up to 70% of women with PCOS have some degree of insulin resistance — a hormonal imbalance that triggers a cascade of symptoms throughout the body.
How PCOS Affects Your Body
- Insulin resistance drives excess androgen production
- High androgens cause acne, facial hair, and hair thinning
- Weight gain becomes harder to manage
- Irregular or missing periods are common
What You May Be Experiencing
- Irregular or missing periods
- Stubborn weight gain, especially mid-section
- Acne that won't respond to typical treatments
- Unwanted facial or body hair
- Hair thinning or shedding
- Difficulty getting pregnant

The Science Behind Metformin for PCOS
Metformin is one of the most commonly prescribed medications for PCOS, with decades of clinical evidence supporting its use for insulin resistance and related hormonal symptoms.
Targets Insulin Resistance
Metformin reduces glucose production in the liver and improves how your cells respond to insulin — the metabolic root of most PCOS symptoms.
Lowers Androgen Levels
When insulin drops, your body produces fewer androgens (testosterone, DHEA-S). Lower androgens mean less acne, less unwanted hair, and less hair thinning.
Supports Weight Management
Metformin helps break the cycle of insulin-driven fat storage, making diet and exercise more effective for women with PCOS.
Extended Release = Better Tolerance
The ER formulation releases metformin gradually throughout the day, dramatically reducing the nausea and GI issues that cause many women to stop treatment.
Metformin has been FDA-approved for decades and is one of the most prescribed medications in the world

Common Questions About Metformin for PCOS
Will metformin help my PCOS?
Metformin is one of the most commonly prescribed medications for PCOS. It improves insulin resistance — the underlying driver of many PCOS symptoms including irregular periods, acne, weight gain, and excess hair growth. Most women notice improvements within 2–3 months.
What PCOS symptoms does metformin treat?
Metformin primarily targets insulin resistance, which can improve: period regularity, acne, weight management, androgen levels (reducing facial hair and hair thinning), and fertility. It works best as part of a comprehensive approach including diet and exercise.
Can I take metformin with spironolactone?
Yes — metformin and spironolactone are commonly prescribed together for PCOS. Metformin handles insulin resistance while spiro blocks androgens. Through Oana, both prescriptions are $39/month combined ($22 metformin + $17 spironolactone).
What about the stomach side effects?
Oana prescribes metformin ER (Extended Release), which releases the medication slowly and significantly reduces nausea, diarrhea, and stomach upset. Most women tolerate ER much better than immediate-release metformin.
Will metformin help me lose weight?
Metformin can support weight management by improving insulin resistance and reducing insulin-driven fat storage. It's not a weight loss drug on its own, but many women with PCOS find it makes diet and exercise more effective.
