Polycystic Ovary Syndrome (PCOS) is a complex, multi-system disorder that affects more than just the reproductive system. It can manifest in a variety of ways, with symptoms differing from person to person. Common symptoms include irregular menstrual cycles, amenorrhea (absence of menstruation), unwanted weight gain, and hirsutism (excessive hair growth). Some individuals may also experience the formation of multiple cysts on their ovaries. Initially, symptoms may appear alone, with just one or two signs. However, as the condition progresses, more symptoms usually develop.
