What are the reasons for irregular menstruation in girls?

The reasons for irregular menstruation in girls are complex and may be related to a variety of factors, including physiology, psychology, environment, and lifestyle. The menstrual cycle and bleeding volume may be affected by hormone levels, uterine and ovarian function. At the same time, emotional stress, bad lifestyle habits, diseases, and medications may also lead to irregular menstruation.

1. Physiological factors: Hormone levels are an important factor affecting the menstrual cycle. If hormone levels are unbalanced, such as abnormal estrogen and progesterone levels, it may cause irregular menstruation. Abnormal uterine and ovarian function may also cause irregular menstruation.

2. Psychological factors: Psychological factors such as emotional stress, anxiety, and depression may affect the menstrual cycle. Long-term mental stress may lead to dysfunction of the hypothalamus-pituitary-ovarian axis, which in turn affects the menstrual cycle.

3. Environmental factors: Environmental factors may also affect the menstrual cycle. For example, environmental pollution and excessive exposure to electromagnetic waves may have an adverse effect on the menstrual cycle.

4. Bad living habits: Bad living habits, such as staying up late for a long time, excessive weight loss, irregular diet, etc., may lead to a decline in body function, affect endocrine balance, and then lead to irregular menstruation.

5. Diseases and drugs: Some diseases, such as polycystic ovary syndrome and thyroid dysfunction, may affect the menstrual cycle. At the same time, some drugs, such as birth control pills and antidepressants, may also affect the menstrual cycle.
