Hormonal fluctuations during the menstrual cycle are the primary cause of mood swings in girls and women. As hormone levels, specifically estrogen and progesterone, rise and fall in the days leading up to and during menstruation, they significantly impact brain chemistry and neurotransmitter levels. This hormonal interplay leads to emotional and psychological changes, manifesting as mood swings, irritability, anxiety, and even depression in some individuals.
The Role of Hormones
- Estrogen and Progesterone: These hormones, crucial for reproductive health, undergo dramatic shifts throughout the menstrual cycle. These shifts affect the production of serotonin, a neurotransmitter that regulates mood. [Source: Why Do You Get Cranky During Your Period? - The Women's Center]
- Serotonin Imbalance: Fluctuations in serotonin levels are strongly linked to mood changes. A decrease in serotonin can contribute to feelings of irritability, sadness, and emotional instability. [Source: Why Do You Get Cranky During Your Period? - The Women's Center]
Premenstrual Syndrome (PMS) and Premenstrual Dysphoric Disorder (PMDD)
Many women experience premenstrual syndrome (PMS), a collection of physical and emotional symptoms that occur in the days leading up to their period. Mood swings are a common symptom of PMS.

PMDD involves significantly more intense emotional symptoms, severely impacting daily life. [Source: Menstrually Related Mood Disorders - Center for Women's Mood ...]
Individual Sensitivity
It's important to note that the severity of PMS symptoms, including mood swings, varies widely among individuals. Some women are more sensitive to hormonal changes than others. This sensitivity can influence the intensity and frequency of experienced mood swings. [Source: Period mood swings: PMS, symptoms, and treatments]
Other Contributing Factors
While hormonal changes are the primary cause, other factors can exacerbate mood swings during menstruation:
- Stress
- Lack of sleep
- Poor diet
- Lack of exercise
In conclusion, understanding the connection between hormonal fluctuations, neurotransmitter levels, and emotional responses provides crucial insight into the cause of mood swings during menstruation.
