What is PCOS?
A note on the name: MedlinePlus, the NIH’s consumer health site, now calls the condition polyendocrine metabolic ovarian syndrome (PMOS) and says it was previously called PCOS. The new name is meant to show that it affects many systems in the body, not only the ovaries.[8] This page keeps “PCOS”, the name most people still search for; both refer to the same condition.
The NIH’s child health institute (NICHD) describes PCOS as a set of symptoms linked to a hormonal imbalance in people with ovaries. Clinicians look for two or more of three features: no ovulation, which shows as light or skipped periods; high androgen levels (hormones such as testosterone); and follicle growths on one or both ovaries.[1]
NICHD adds that people with PCOS may also have metabolic issues such as insulin resistance or obesity, which is one reason weight and metabolic health come up so often in PCOS care.[1][3]
Are GLP-1 medicines approved for PCOS?
No. The current US labels for Wegovy®, Ozempic®, Zepbound® and Mounjaro® do not list PCOS as an indication.[4][5][6][7] That does not mean a clinician won’t consider them; it means the label does not describe PCOS-specific results.
The 2023 international evidence-based PCOS guideline, developed with ASRM, the Endocrine Society, ESE and ESHRE, puts lifestyle support at the centre and also discusses weight-management medicines for adults with PCOS. It frames these as a shared decision between the person and their clinician.[2]
Which label details matter most with PCOS?
| What the label says | Why it matters with PCOS | What to log in PepLabo |
|---|---|---|
| Semaglutide: stop at least 2 months before a planned pregnancy, because it stays in the body for a long time.[4][5] | Fertility is often part of PCOS care, so timing is worth planning early. | Your restart or stop dates in the dose history. |
| Tirzepatide may make oral hormonal contraceptives less reliable; for the first four weeks and the four weeks after every step up, the labels point to a contraceptive that is not swallowed, or a condom alongside the pill.[6][7] | Many people with PCOS use the pill to regulate their cycle. | Dose increases (visible in your history) and a note when you add a backup method. |
| Not labelled for PCOS.[4][5][6][7] | Results described in the labels come from other populations. | Weight trend, symptoms and cycle notes for your clinician to judge. |
What does PepLabo not do?
PepLabo is a log. It does not diagnose, measure hormones or body composition, suggest a dose or tell you when to change one.
There is no dedicated period tracker: period start dates, spotting or a missed period go in the note of a side-effect check-in.
Wegovy® and Ozempic® are registered trademarks of Novo Nordisk A/S; Zepbound® and Mounjaro® are registered trademarks of Eli Lilly and Company. They are named only to identify the medicines and their labels. PepLabo has no affiliation with these companies.
