Abstract: Polycystic ovary syndrome (PCOS) is considered to be one of the most common female endocrine diseases. In addition to the abnormal reproductive function caused by this disease, the metabolic disorders and related complications caused by PCOS are also important factors affecting the quality of life of PCOS patients. Current research results indicate that although omega-3 fatty acids are one of the effective drugs to alleviate PCOS -related complications, how to use omega-3 fatty acids in the diet to systematically control the complications in PCOS patients still needs further research. This paper reviews the effects of omega-3 fatty acids on BMI, insulin resistance index, abnormal inflammatory factors and steroid hormone levels in PCOS patients. We summarize the results of clinical efficacy on the treatment of PCOS complications with omega-3 fatty acids.
