Also known as: Menstrual Irregularity
Irregular periods include cycles shorter than 21 days, longer than 35 days, missed periods, or significant variation in cycle length month to month.
A normal menstrual cycle ranges from 21-35 days, with some variation between cycles being common. Irregularity becomes a concern when cycle length varies significantly or periods are absent.
PCOS is the most common hormonal cause of irregular periods, affecting up to 10% of women of reproductive age. Thyroid disorders — both hypo and hyperthyroidism — also frequently disrupt menstrual regularity.
Stress, rapid weight change, excessive exercise, and eating disorders can suppress the hormonal signals that drive the menstrual cycle, causing oligomenorrhea or amenorrhea.
