Polycystic ovary syndrome (PCOS) is one of the leading causes of Irregular Periods in women. PCOS is a hormonal disorder where the ovaries produce higher-than-normal levels of androgens (male hormones), which can disrupt the regularity of the menstrual cycle. As a result, women with PCOS often experience infrequent, irregular, or prolonged periods, and in some cases, may not have periods at all. This is due to the ovaries' inability to properly release eggs (ovulation), which is essential for regular menstruation. PCOS is also associated with other Symptoms such as weight gain, acne, and excess body hair (hirsutism). In addition to irregular periods, women with PCOS may also struggle with fertility, as ovulation is often unpredictable.
