Doctor's answer (1)
Dr. Zhao Xiaodong
Menstruation occurring 15 days earlier than usual could be due to one of the following reasons:
1. Stress and emotional changes: Mental stress, anxiety, or emotional fluctuations can affect a woman's hormone secretion, leading to changes in the menstrual cycle.
2. Weight changes: Rapid weight gain or loss, especially due to extreme dieting, may disrupt normal hormonal balance and affect the menstrual cycle.
3. Hormonal imbalance: Conditions such as ovarian cysts, polycystic ovary syndrome (PCOS), or thyroid dysfunction can cause hormonal imbalances, leading to irregular menstruation.
4. Medication effects: Certain medications, such as contraceptives, hormone therapy drugs, or specific psychiatric medications, may alter the menstrual cycle.
5. Increased physical activity: High-intensity exercise or a sudden increase in activity levels may affect hormone secretion and lead to changes in the menstrual cycle.
6. Age and reproductive stage: Women in early puberty or approaching menopause often experience unstable menstrual cycles.
7. Lifestyle habits: Insufficient sleep or irregular daily routines may also affect the menstrual cycle.
If menstrual irregularities persist or are accompanied by other symptoms such as severe pain or abnormal bleeding, it is advisable to consult a healthcare provider promptly.
