There has never been more on offer to a woman with PMOS (PCOS) who wants to lose weight. Apps, coaches, diet programmes, supplements, new medicines, old medicines - all of them marketed with confidence, some of them backed by evidence, and almost none of them explained against your specific biology.

This is a checklist for that moment. Not advice for or against any particular option - just the questions that separate an informed decision from an expensive experiment. Take them to your doctor, your programme, or your own research. Good options survive good questions.

Questions about your own body first

Has my insulin resistance actually been measured? With an OGTT (a two-hour glucose test) and ideally insulin levels - not just a fasting glucose, which misses around 40% of glucose disorders in this condition. If the answer is no, this is step one, before any treatment choice.
Which PMOS phenotype do I have? There are four presentations, and they respond differently. A treatment aimed at a metabolic phenotype may be aimed at nothing in a woman with a different type.
What’s my baseline? Weight is one number. Androgens, lipids, blood pressure, cycle regularity, and mood are the fuller scoreboard. If you don’t know the starting line, you can’t know if anything worked.

Questions about the treatment itself

What is the evidence for this in PMOS specifically? Results in the general population, or in type 2 diabetes, don’t automatically transfer. It’s fair to ask what’s known in women like you - and honest answers sometimes include “the evidence is still developing.”
What happens when I stop? For any programme or medicine, ask about what tends to happen after it ends. If maintenance requires the treatment to continue indefinitely, you deserve to know that before starting, not after.
What does this cost over a year - realistically? Not per month. Per year, including consultations, monitoring tests, and renewals. Sustainability is a medical variable: a treatment you can only afford for three months is a three-month treatment.
What are the side effects and who monitors them? Every effective intervention has trade-offs. Ask what they are, how common, and who is watching for them - a named person, on a schedule, not “come back if something feels wrong.”
How does this fit my fertility plans? Some options are incompatible with pregnancy or actively trying to conceive. If children are anywhere in your next few years, this question moves to the top of the list.

Questions about the plan around the treatment

How will we define “working”? Agree upfront: which numbers, reviewed when? A treatment without a review date is a subscription, not a plan.
What’s the plan for the rest of my PMOS? Weight is one thread of a whole-body condition. Cycles, skin, hair, mood, and long-term cardiovascular health still need a home in the plan - whoever is prescribing the weight-loss part.
Who is coordinating all of this? If the diet comes from one place, the prescription from another, and the labs from a third, name the person who sees the whole picture. If nobody does - that’s the gap to fix first.

“Good options survive good questions. It’s the ones that discourage questions you should worry about.”

If the answers feel thin

Silence, vagueness, or irritation in response to these questions isn’t a verdict on the treatment - but it is a verdict on the process around it. You’re allowed to pause. You’re allowed to get an independent, specialist read on your labs and your options before committing your body and your money to anything. That’s not being difficult. That’s being the informed patient every good clinician actually wants.
