PCOS and Pregnancy: What Changes Once You Conceive

Polycystic ovary syndrome (PCOS), recently renamed polyendocrine metabolic ovarian syndrome (PMOS), does not disappear after conception. Once pregnant, existing insulin resistance and hormonal imbalance can intensify as pregnancy hormones rise, raising the risk of gestational diabetes, hypertensive disorders, miscarriage, and preterm birth. This is why doctors monitor PCOS pregnancies more closely than others, with earlier blood sugar screening, more frequent blood pressure checks, and extra growth scans. Most women with PCOS still go on to have healthy pregnancies with early care and simple lifestyle adjustments.
