INTERVENTIONAL
Conditions
Summary
The aim of this study is to elucidate the effects of red yeast rice on the improvement of symptoms in patients with polycystic ovary syndrome（PCOS）, and to analyze the dose-response relationship between intestinal microbiota and its metabolite, hydroxyindole, and clinical indicators of PCOS. The main questions it aims to answer are: How effective is red yeast rice in treating PCOS? Does the indole metabolic pathway of gut microbiota play a crucial role in the improvement of PCOS symptoms by red yeast rice? Participants will take 6 grams of red yeast rice daily for 6 months, and records will be kept of their PCOS clinical symptoms and indicators before the intervention, at the 3rd month post-intervention, and at the 6th month post-intervention. Additionally, biological samples from feces and serum will be collected at these time points.
