Concerned about Irregular Periods? It’s common.
Irregular periods are a common concern among women, especially during the beginning and end of the reproductive years. The prevalence of irregular menstrual cycles can vary based on the definition used, the population studied, and the age group considered. Here are some general statistics:
Adolescence: It's common for girls to experience irregular periods for a few years after menstruation begins. During the first two years after menarche (the onset of menstruation), as many as 50% or more of cycles can be anovulatory (no ovulation occurs), leading to irregularities. Over time, as the hormonal system matures, most girls will develop regular cycles.
Reproductive Age: Among women of reproductive age, the prevalence of irregular menstrual cycles can range from 14% to 25%, depending on the criteria used and the population studied. Factors that can lead to irregularities include polycystic ovary syndrome (PCOS), which affects about 6% to 12% of U.S. women of reproductive age, stress, significant weight changes, certain medications, and other medical conditions.
Perimenopause: As women approach menopause, it's common to experience irregular cycles again. The perimenopausal phase, which can last for several years, often sees hormonal fluctuations that can lead to varying cycle lengths and missed periods.
Other Factors: Conditions like thyroid disorders, eating disorders, rigorous exercise, and certain medications can also lead to menstrual irregularities.
It's crucial to understand that while irregular periods can be a part of natural life stages like puberty and perimenopause, persistent irregularities in women of reproductive age should be evaluated by a healthcare provider to rule out underlying medical conditions.
If you or someone you know experiences irregular menstrual cycles, it's always a good idea to consult with a healthcare provider to determine the cause and get appropriate guidance.
