Many women ask, PCOD or PCOS – which is more dangerous? While both are hormonal disorders affecting the ovaries, PCOS (Polycystic Ovary Syndrome) is generally considered more serious. PCOD (Polycystic Ovarian Disease) involves hormonal imbalance and irregular periods, but is often manageable with lifestyle changes. In contrast, PCOS is a metabolic condition that may lead to infertility, type 2 diabetes, obesity, and heart problems if not treated in time. The impact of each condition varies from person to person.
