Women with polycystic ovary syndrome (PCOS) exhibit a distinct metabolic profile characterized by elevated lactate, long-chain fatty acids, and specific amino acids (valine, leucine, serine, threonine, phenylalanine, tyrosine, ornithine), alongside reduced glucose, glycine, and proline, which serves as a biomarker for insulin resistance and diabetes risk.
If you have PCOS, your body's metabolism is fundamentally different, affecting how you process sugars, fats, and proteins. This isn't just about weight; it's about your risk for diabetes and heart disease. Key markers like low glycine and high valine/leucine can help doctors assess your risk. Managing insulin resistance through diet and exercise is crucial, as it addresses the root metabolic dysfunction, not just the symptoms.
Our results showed that carbohydrate, lipid and amino acid metabolisms were influenced in PCOS. The levels of lactate, long-chain fatty acids, triglyceride and very low-density lipoprotein were elevated, while glucose, phosphatidylcholine and high-density lipoprotein (HDL) concentrations were reduced in PCOS patients as compared with controls. Additionally, the levels of alanine, valine, serine, threonine, ornithine, phenylalanine, tyrosine and tryptophan were generally increased, whereas the levels of glycine and proline were significantly reduced in PCOS samples compared to controls.
Why this rating
Large sample size (217 PCOS, 48 controls) and use of two complementary metabolomic platforms (NMR and GC/TOF-MS).

- A reduced ratio of branched-chain amino acids (BCAA) to aromatic amino acids (AAA) in plasma is a specific metabolic signature of PCOS that is independent of obesity and insulin resistance, distinguishing it from type 2 diabetes profiles.Good
- Ovulatory dysfunction in PCOS is associated with elevated levels of serine, threonine, phenylalanine, tyrosine, and ornithine, suggesting that increased ovarian uptake of these amino acids contributes to anovulation.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
