Irregular periods can be caused by various factors. Here are some common culprits:

1. Hormonal Imbalances: Fluctuations in hormones, especially estrogen and progesterone, can disrupt the regular menstrual cycle.

2. Stress: High stress levels can impact hormonal balance, potentially leading to irregular periods.

3. Weight Changes: Significant weight loss or gain can affect hormones and disrupt the menstrual cycle.

4. Polycystic Ovary Syndrome (PCOS): A common condition where small cysts form on the ovaries, often causing irregular periods.

5. Thyroid Issues: Disorders like hypothyroidism or hyperthyroidism can influence menstrual regularity.

6. Excessive Exercise: Intense physical activity, especially when combined with low body weight, can affect hormone production and lead to irregular periods.

7. Poor Nutrition: Inadequate or imbalanced nutrition can impact overall health, including menstrual cycles.

8. Perimenopause: The transition period before menopause can bring about irregularities in menstrual cycles.

9. Certain Medications: Some medications, such as contraceptives or antipsychotics, may affect menstrual regularity.

10. Chronic Illness: Conditions like diabetes or inflammatory disorders can contribute to irregular periods.

11. Uterine Abnormalities: Structural issues in the uterus can lead to irregular bleeding.

12. Pelvic Inflammatory Disease (PID): Infections in the reproductive organs may cause irregular periods.

13. Early Pregnancy: Implantation bleeding or hormonal changes in early pregnancy can mimic irregular periods.

14. Breastfeeding: Changes in hormones during breastfeeding can result in irregular menstrual cycles.

15. Excessive Caffeine or Alcohol: High intake of caffeine or alcohol may impact hormonal balance and menstrual regularity.

It's important to note that these factors can interact, and the specific cause of irregular periods varies from person to person. If you're experiencing irregularities or have concerns, consulting with a healthcare professional can help identify the underlying cause and guide appropriate management.
