Polycystic ovary syndrome, or PCOS, is a common endocrine condition, affecting anyone of reproductive age. However, signs and symptoms most commonly begin to appear in people during their late teenage years to their early 20’s. Whilst symptoms will appear differently in everyone they may include; irregular or no periods, difficulty getting pregnant, hirsutism (excess hair growth on the face and body), fluctuations in weight, acne and oily skin, and thinning or loss of hair from the head.
