Irregular Periods: 8 Main Causes and Effective Treatments

Irregular periods are common yet disruptive, stemming from various causes, including hormonal fluctuations, health conditions, and lifestyle factors. Normally, a woman’s menstrual cycle occurs every 28 days, though changes during puberty, perimenopause, or due to other factors can disrupt this pattern. Irregular cycles might include periods that are consistently shorter than 21 days, longer than 35 days, or missed altogether, with heavy or light bleeding and unexpected spotting. Tracking cycles through a calendar or app can help recognize patterns and discuss them with a doctor.
Here, we break down the main causes of irregular periods and share some effective treatments, from traditional options to advanced therapies, to help achieve menstrual regularity.
