PCOD (Polycystic Ovarian Disease) and PCOS (Polycystic Ovary Syndrome) are often used interchangeably, but they refer to different conditions. The key difference between PCOD and PCOS lies in their severity and long-term effects.PCOD is a condition where the ovaries contain many immature or partially mature eggs, leading to an imbalance in hormone production. This may cause irregular periods, weight gain, and acne. However, with proper care and lifestyle changes, the condition can often be managed effectively.PCOS, on the other hand, is a more severe hormonal disorder that can affect multiple body systems. It involves an imbalance of hormones that can disrupt ovulation, leading to infertility, excessive hair growth, and higher risk for conditions like diabetes and heart disease. PCOS requires more comprehensive treatment and monitoring.In summary, while both PCOD and PCOS involve ovarian dysfunction, PCOS is a more complex, long-term condition with higher risks, whereas PCOD is typically less severe and can be managed with lifestyle changes.
