7 common causes behind irregular periods

A regular menstrual cycle is often a sign of good health, but many women experience irregular periods at some point in their lives. While occasional fluctuations are normal, persistent irregularities may signal underlying health conditions. Here are seven possible reasons for irregular periods.

1. Stress and Lifestyle Changes

High stress levels can disrupt hormone balance, affecting the timing of menstruation. Poor sleep, sudden weight changes, and excessive physical exertion can also play a role in irregular cycles.

2. Hormonal Imbalances

Conditions like polycystic ovary syndrome (PCOS) and thyroid disorders can lead to hormonal fluctuations that affect menstrual regularity. Imbalances in estrogen and progesterone levels may cause missed periods or unpredictable cycles.

3. Excessive Exercise or Weight Fluctuations

Extreme weight loss, obesity, or excessive physical activity can impact hormone production, leading to skipped or irregular periods. A healthy balance of diet and exercise supports hormonal stability.

4. Birth Control and Medications

Certain contraceptives—like hormonal birth control pills, IUDs, or injections—can alter menstrual patterns. Some medications, including antidepressants and blood thinners, may also contribute to irregular cycles.

5. Perimenopause or Menopause

As women approach their late 40s or early 50s, menstrual cycles become erratic due to fluctuating estrogen levels. Perimenopause, the transitional phase before menopause, is marked by changes in period frequency and intensity.

6. Underlying Medical Conditions

Reproductive health issues such as uterine fibroids, endometriosis, or pelvic inflammatory disease (PID) can disrupt menstrual cycles. Managing these conditions with medical guidance helps regulate periods.
