How Do You Treat PCOS? From Weight Loss to Fertility

PCOS is treated through a combination of lifestyle changes, medications, and ongoing monitoring, with the specific approach depending on whether your main concerns are irregular periods, acne and excess hair growth, difficulty getting pregnant, or metabolic health. There’s no single cure, but most symptoms can be significantly improved with the right strategy.

Weight Loss Has an Outsized Effect

If you carry extra weight, losing even a modest amount can shift the hormonal picture dramatically. Each 1% reduction in body weight is associated with a roughly 6% increase in the odds of resuming ovulation. In a randomized controlled trial of women with PCOS and obesity, more than 50% of those who lost any weight at all recovered regular ovulation, compared to just 19% of those who didn’t lose weight. The sweet spot appeared to be 10 to 15% total weight loss, where ovulation recovery reached 100% in that study group.

Weight loss works because it lowers insulin levels and reduces circulating androgens (the hormones responsible for acne, hair growth, and disrupted cycles). You don’t need to hit an ideal body weight. A loss of 5 to 10% is the threshold where reproductive function starts to measurably improve, and it also brings down cholesterol and blood sugar levels. The method of weight loss matters less than the consistency: structured dietary changes and regular physical activity are the foundation of every PCOS treatment guideline.

Regulating Your Cycle With Hormonal Birth Control

Combined oral contraceptives are the most common first-line treatment for PCOS symptoms when pregnancy isn’t the goal. They work by suppressing the pituitary signals that drive the ovaries to overproduce androgens, and they increase a protein in your blood that binds up free testosterone, reducing it by roughly 50%. The practical result is more predictable periods, less acne, and slower hair growth over time.

Beyond symptom control, regular withdrawal bleeds from the pill protect the uterine lining. Without regular periods, the lining can build up over months or years, which raises the risk of abnormal cell changes. If you can’t or prefer not to take estrogen-containing pills, a progestin-only option or a hormonal IUD can provide that uterine protection, though it won’t address androgen-driven symptoms as effectively.

Managing Excess Hair and Acne

Hormonal birth control handles mild to moderate acne well, but hirsutism (coarse, dark hair on the face, chest, or back) often needs additional treatment. Spironolactone, typically prescribed at 100 to 200 mg daily, blocks androgen activity at the skin level. It’s effective, but slow. Expect at least six months before you notice meaningful changes: hair growth slows first, then individual hairs become finer and lighter. Because spironolactone can cause birth defects, it’s almost always paired with reliable contraception.

Topical treatments and hair removal methods like laser or electrolysis can be used alongside medication. Many women find that combining a systemic treatment (the pill plus spironolactone) with a physical method gives the best cosmetic results while waiting for the medication to take full effect.

Improving Insulin Resistance

Insulin resistance is present in the majority of women with PCOS, regardless of weight. When your cells respond poorly to insulin, your body compensates by producing more of it, and high insulin directly stimulates the ovaries to produce excess androgens. Breaking this cycle is central to long-term management.

Metformin is the most widely used medication for this purpose. It works by reducing the amount of glucose your liver releases and improving how efficiently your body uses insulin. In studies of women treated for at least six months, more than 90% resumed regular menstruation. The clinical effect typically doesn’t kick in below 1,000 mg per day, and the optimal dose ranges from 1,500 to 2,550 mg daily. Because it commonly causes nausea and digestive upset early on, most doctors start with 500 mg taken with a meal and increase gradually over weeks.

Myo-inositol, a supplement available without a prescription, has shown benefits for insulin sensitivity in PCOS at doses of 2 to 4 grams daily over 12 to 24 weeks. It’s not as potent as metformin, but some women use it as a complement or as an alternative when they can’t tolerate metformin’s side effects.

Fertility Treatments for PCOS

PCOS is one of the most treatable causes of infertility. The core problem is irregular or absent ovulation, and several medications can reliably trigger it.

Letrozole is now considered the first-choice ovulation induction drug for PCOS. In a head-to-head trial against the older standard, clomiphene citrate, letrozole produced a clinical pregnancy rate of 61% compared to 43% with clomiphene. Ovulation rates per cycle were also higher with letrozole (75% versus 67%). Letrozole works by temporarily lowering estrogen, which tricks the brain into sending a stronger signal to the ovaries to develop and release an egg.

Clomiphene remains a reasonable option, especially where letrozole isn’t available or covered by insurance. When neither oral medication works, injectable hormones are the next step, though they require closer monitoring due to a higher risk of multiple pregnancies. For women who’ve exhausted medication options, a surgical procedure called ovarian drilling can restore ovulation. About 50% of women who undergo it conceive within the first year. It’s typically reserved for cases where medications have failed or aren’t an option.

Newer Medications on the Horizon

GLP-1 receptor agonists, the class of drugs that includes liraglutide, have generated significant interest for PCOS. A meta-analysis found that adding a GLP-1 medication to existing treatment reduced BMI by an average of about 1.4 points more than controls. However, the evidence for improvements in blood sugar, insulin levels, hirsutism, or menstrual regularity remains too weak to draw firm conclusions. Notably, no published studies have yet tested semaglutide or tirzepatide specifically in PCOS populations, so the enthusiasm currently outpaces the data.

Screening for Long-Term Health Risks

PCOS isn’t just a reproductive condition. It carries elevated risks for type 2 diabetes, high cholesterol, and cardiovascular disease that persist well beyond your reproductive years. International guidelines recommend that every woman with PCOS, regardless of weight, get a glucose tolerance test and a full lipid panel at the time of diagnosis.

The glucose tolerance test (a two-hour blood draw after drinking a sugary solution) is more accurate than a simple fasting glucose for catching early insulin problems, which are common in PCOS. After the initial test, it should be repeated every one to three years depending on your individual risk factors. If you’re planning a pregnancy, testing is recommended before conception and again at 24 to 28 weeks of pregnancy, since PCOS significantly raises the risk of gestational diabetes.

Lipid screening frequency after diagnosis depends on whether your initial results are abnormal. If your cholesterol and triglycerides come back normal and you don’t have other cardiovascular risk factors, less frequent monitoring is reasonable. If they’re elevated, your doctor will track them more closely and may recommend treatment.
