The jeans at the back of the closet
Your jeans still fit everywhere except the waist.
That's the strange part. Your arms haven't changed, and neither have your legs. Your boots still zip, your sleeves still button, and your rings fit the way they always have. It's only the waistband.
So you did what most of us do. You bought the next size up, and then the one after that. At some point you started choosing dresses and anything with a tie instead of a waistband. The old jeans went to the back of the closet instead of the donation bag, because giving them away felt like admitting something.
You hadn't changed how you ate. If anything, you were more careful than you'd been at thirty. When you asked about it, everyone told you the same thing. Your metabolism is slowing down. It's perimenopause. It happens to every woman.
Eventually you stopped asking and put it down to getting older.
A lot of women end up in the same place. In a 2025 study, researchers interviewed twenty-nine women with PCOS who were going through or past menopause, and most of them described exactly this. Sixty-nine percent said their weight gain had gotten worse with age, and about a third had given up hope that it would change. One woman summed it up: You have to just accept that it will never be better.
If you've felt that way, it makes sense. You were working with the information you had, and nobody had given you the whole picture.
Where the weight goes is the clue
Where your body stores weight says something about your hormones.
When weight goes on evenly, across your arms, face and middle, it's mostly about calories. When it goes almost entirely to your stomach while your arms and legs stay the same, that points to a hormone problem, and it's the kind of problem a blood test can pick up.
You probably noticed this pattern years ago. Nobody told you it meant anything, so you assumed you were being vain about your looks. You weren't. It was the most useful clue you had, and the problem behind it can be treated.
Why the fat goes to your middle
Most women with PCOS have insulin resistance. Your cells don't respond well to insulin, so your pancreas makes extra to make up for it. All that insulin has two effects. It tells your ovaries to make more androgens, which are hormones like testosterone. And it tells your liver to make less of a protein called SHBG, which normally keeps testosterone in check. The result is more active testosterone in your body.
Androgens affect more than your skin and hair. They also affect where your body stores fat.
An NIH-funded study at UCLA looked at women with PCOS who were a normal weight and found that they stored fat differently from women the same size without PCOS. They had more fat packed around the organs in their abdomen, and less fat under the skin of their belly, hips and thighs. The women whose androgen levels were normal didn't have this pattern at all.
So your arms and legs didn't stay the same by luck. The fat was going somewhere else.
That matters for your health, not just your clothes. The fat under your skin, the kind you can pinch on your hips and thighs, is fairly harmless storage. Visceral fat, the fat around your organs, sends a steady supply of fatty acids and inflammation straight to your liver. Your liver then makes more sugar and becomes less sensitive to insulin, whatever your weight. That pushes insulin even higher, which sends more fat to your middle, and the cycle keeps going.
That's why doctors should treat this as a health issue. Women with PCOS have about four times the odds of developing type 2 diabetes, and a review of more than a million women found PCOS was linked to higher odds of heart disease. The 2023 international guideline now says every woman with PCOS should have her heart risk checked, whatever her age or weight. A rising A1c is an early warning about your blood sugar, whatever you look like.
This is also why trying harder with diet and exercise so often doesn't work. The hormones are driving the weight gain, and they come first. Your effort was never the problem. You were up against hormones that nobody had treated.
Perimenopause is part of it, too
Your doctor wasn't making it up when they blamed perimenopause.
As estrogen drops, fat really does move from the hips and thighs toward the stomach, and that happens separately from getting older. During the menopause transition, fat around the organs goes from about five to eight percent of total body fat to fifteen or twenty percent.
So whoever told you it was perimenopause was partly right. They just didn't finish the thought. When PCOS and perimenopause happen at the same time, both of them push weight toward your middle, and that's exactly why this gets missed so often.
The tests and the treatments
Before you talk about medication, ask for some numbers. An HbA1c is a blood test that shows your average blood sugar over the past three months. An oral glucose tolerance test is even better, and the 2023 guideline calls it the first choice. Ask for a lipid panel (a cholesterol test), a blood pressure check and a thyroid test too. If the weight came on quickly, ask what else your doctor is ruling out, including Cushing's syndrome, and whether any of your medications could be playing a part.
There are two medications worth asking about.
Metformin lowers the amount of sugar your liver releases and helps your body use insulin better. The international guideline recommends it for the metabolic side of PCOS. It's approved for type 2 diabetes, and doctors prescribe it "off-label" for PCOS, which means it's approved for something else but can legally be used for this. That's very common. The main side effect is an upset stomach, especially in the first few weeks, and the extended-release version is usually easier to take. If you're on it long term, ask to have your B12 checked.
GLP-1 medications slow down how quickly your stomach empties, reduce your appetite, and help your body use insulin. In PCOS studies they've led to modest weight loss and better insulin resistance in the short term, but they haven't clearly lowered testosterone, and there isn't much research yet on fertility. They have real downsides, too: nausea and constipation, high cost and insurance battles, muscle loss if you don't get enough protein and strength training, and weight regain for many people who stop. They can't be used during pregnancy and need to be stopped well before you try to conceive.
You could say something like this at your appointment:
My weight gain has been almost all in my middle, and my arms and legs haven't changed. I think it might be insulin resistance. Can we check an HbA1c or a glucose tolerance test and a lipid panel, and talk about whether metformin or a GLP-1 makes sense for me?
Give any treatment a few months. The scale usually isn't the first thing to change. Your A1c, your triglycerides (a type of fat in your blood), your energy in the afternoon and your periods often improve first, and those count.
Getting it looked at
Start with your primary care doctor, your OB-GYN or an endocrinologist (a hormone specialist). Bring the question above, and ask for copies of your results.
It helps to know going in that PCOS gets missed a lot. It affects about one in ten women, and it's still often treated with a birth control prescription and nothing else. In that 2025 study, one woman had seen two endocrinologists, an OB-GYN and her family doctor, and felt that none of them were listening. If your appointment goes the same way, it tells you more about that doctor's training than about your symptoms. You can ask again, or see someone else.
If you'd like a doctor who focuses on PCOS, there are telehealth options. Allara Health is an online practice for PCOS and women's hormone and metabolic health. It pairs doctors with registered dietitians and takes many major insurance plans, though it isn't available in every state. Sesame lets you book an appointment with a specific doctor at a set cash price, with no insurance or referral needed. That can help if you're uninsured, between plans, or facing a six-month wait to see an endocrinologist.
I have no financial relationship with either company. I'm not an affiliate, and I don't get paid if you book. I mention them because telling you to find a doctor who understands PCOS isn't much help without somewhere to start.
PCOS can be managed but not cured, and I can't promise you a particular number or timeline. But the weight you were told to accept as part of turning forty is something doctors can measure and treat, and many women with numbers like yours have brought them down. You don't have to make peace with it. You just need someone to look at it properly.
This is my experience and my reading of the research, not medical advice. Nothing here should replace a conversation with a clinician who knows your history.
