PCOD (Polycystic Ovarian Disease) and PCOS (Polycystic Ovarian Syndrome) are distinct conditions, with PCOD being less severe and more common, while PCOS is a metabolic disorder with serious health risks. PCOD involves the presence of many immature eggs leading to hormonal disturbances, whereas PCOS results in a higher production of male hormones and multiple follicular cysts, causing more severe symptoms and potential complications. Understanding these differences is crucial for appropriate management and treatment.
