Assessment of Metabolic Changes in Response to Glcuose Intake in Women With Polyendocrine Metabolic Ovarian Syndrome (PMOS)

Polyendocrine metabolic ovarian syndrome (PMOS), previously known as polycystic ovary syndrome (PCOS), is a common endocrine and metabolic condition affecting women of reproductive age. It is associated with hormonal imbalances, irregular menstrual cycles, elevated androgen levels, and metabolic disturbances such as insulin resistance. These metabolic changes can increase the risk of type 2 diabetes and cardiovascular disease. Insulin resistance means that the body's cells respond less effectively to insulin, a hormone that regulates blood glucose. This leads to compensatory increases in insulin levels, which can further disrupt hormonal balance and contribute to the clinical features of PMOS. This study aims to investigate how the bodies of women with PMOS respond dynamically to glucose intake compared with women without PMOS. A standard clinical test, the oral glucose tolerance test (oGTT), will be used. Participants consume a glucose solution, and blood samples are collected before and two hours afterward. This procedure is routinely used in clinical practice. Women with PMOS will be compared with age- and body mass index (BMI)-matched control participants without PMOS. Blood and urine samples will be analyzed using advanced multi-omics technologies to measure proteins, metabolites, extracellular vesicles, and immune-related signals. The main objective is to understand how metabolic, hormonal, and immune pathways respond over time to a glucose challenge and whether these responses differ in PMOS. Special attention is given to inter-organ communication and systemic metabolic regulation. The study includes two visits. The first visit involves health assessments, questionnaires, and body composition measurements. The second visit includes the glucose tolerance test and blood sampling. In total, approximately 100 mL of blood will be collected across both visits. Participation is voluntary, and participants may withdraw at any time without affecting their medica
