Hormones or Stress? What Really Causes Mood Swings in Women?

While sudden emotional shifts in women are frequently dismissed as mere hypersensitivity, medical science reveals that these mood swings are driven by complex biological changes and lifestyle stressors. Specialists indicate that major life transitions such as puberty, the menstrual cycle, pregnancy, and menopause induce sharp hormonal shifts that directly impact human emotions. According to global reviews by the World Health Organization, approximately 70 to 90 percent of women of reproductive age experience mild to moderate Premenstrual Syndrome (PMS) symptoms at some point in their lives.

The renowned healthcare institution Mayo Clinic notes that fluctuations in estrogen and progesterone during the menstrual cycle are primary catalysts for PMS symptoms like irritability and fatigue. Furthermore, the Mayo Clinic highlights that shifts in serotonin, which is a vital brain chemical, play a significant role in altering human temperament. Medical researchers explain that lower serotonin levels can quickly trigger depression, fatigue, and anxiety. These psychological shifts are highly visible during adolescence due to rapid hormonal surges and the subsequent adaptation to physical changes.

However, emotional fluctuations are not governed by biology alone, as academic, familial, relational, and future-oriented anxieties significantly exacerbate mood swings. Professor Ayesha Mahmuda from the Department of Psychology at the University of Dhaka emphasizes that biological changes work in tandem with environmental and social factors.

She notes that an individual's surroundings and coping mechanisms are crucial since an irregular or undisciplined lifestyle further fuels mental restlessness. She also states that while standard mood swings fluctuate based on immediate stressors, the physical discomfort and pain associated with the menstrual cycle compound the emotional instability.

Medical practitioners warn that if mood swings become severe enough to disrupt education, work, or familial relationships, they may signify Premenstrual Dysphoric Disorder (PMDD). This is a severe condition that requires immediate medical consultation.

Dr. Mohammad Shamsul Ahsan, Associate Professor of Psychiatry at Bangladesh Medical University, explains that mood naturally fluctuates based on time, environment, stress, and personality traits. He points out that women are highly sensitive to emotional stressors and hormonal shifts during menstruation and ovulation. He clarifies that while mood swings occur in healthy individuals, extreme variations can be symptomatic of psychiatric conditions such as bipolar mood disorder, borderline personality disorder, schizophrenia, or substance addiction.

To manage and alleviate daily mood swings, experts universally recommend regular physical exercise, adequate sleep, a balanced diet, and active stress management. Dr. Ahsan advises that identifying the specific root cause is vital for treatment, noting that mania requires medication while borderline personality disorder requires regular counseling. For stress-induced emotional shifts, reducing lifestyle pressures, taking work breaks, and getting sufficient rest are highly effective solutions. Utilizing relaxation techniques such as deep breathing and progressive muscle relaxation also helps stabilize mental health.
