Heightened emotional sensitivity, including crying, is common during the menstrual cycle’s premenstrual phase. Understanding the biological factors behind these emotional shifts can provide reassurance. This article explores these contributing factors.
The Role of Hormonal Shifts
The primary biological mechanism for emotional changes before menstruation is the fluctuation of ovarian hormones, estrogen and progesterone. These hormones shift throughout the menstrual cycle, influencing mood. While estrogen rises early in the cycle, often improving mood, a rapid decline of both estrogen and progesterone in the luteal phase (the week or two before menstruation) significantly impacts mood.
This sharp drop in hormone levels can lead to emotional fluctuations. The menstrual phase, with its low estrogen and progesterone, often brings fatigue and moodiness. These hormonal changes affect the brain’s emotion regulation, contributing to sadness or irritability before a period.
How Neurotransmitters are Affected
Hormonal fluctuations directly influence brain neurotransmitters, especially serotonin. Serotonin, a chemical messenger, regulates mood, sleep, and appetite. A decline in estrogen during the luteal phase can decrease serotonin levels or alter receptor sensitivity. This reduced serotonin activity is linked to sadness, irritability, and crying spells.
Estrogen enhances serotonin production and receptor sensitivity, and decreases serotonin transporter (SERT) activity, allowing more serotonin to remain active. When estrogen drops, these supportive effects diminish, contributing to mood dysregulation. Other neurotransmitters like GABA and dopamine also fluctuate, with declining levels in the luteal phase potentially affecting relaxation, motivation, and pleasure.
Distinguishing PMS from PMDD
Premenstrual Syndrome (PMS) and Premenstrual Dysphoric Disorder (PMDD) both cause emotional and physical symptoms before menstruation, but differ in severity. PMS is common, affecting up to 90% of women with symptoms like mood swings, irritability, anxiety, and fatigue. These symptoms are generally manageable and do not severely disrupt daily functioning.
PMDD is a more severe form of premenstrual distress, affecting 2% to 8% of menstruating individuals. Its symptoms are similar to PMS but are more intense, causing significant mood disturbances that interfere with daily life, work, and relationships. PMDD involves extreme irritability, severe anxiety, marked moodiness, or feelings of hopelessness, potentially leading to thoughts of self-harm. Diagnostic criteria emphasize this functional impairment and the cyclical nature of symptoms, appearing one to two weeks before a period and resolving within days of its onset.
Strategies for Managing Emotional Swings
Lifestyle interventions can help manage emotional sensitivity during the menstrual cycle. Dietary adjustments, such as consuming complex carbohydrates, fruits, and vegetables, are beneficial. Limiting caffeine, sugar, and salt can reduce mood swings and bloating. Eating smaller, more frequent meals helps stabilize blood sugar, preventing mood dips.
Regular physical activity is effective, improving mood by boosting endorphins. Aerobic exercises like walking, running, or swimming, and practices like yoga, can reduce stress, alleviate physical discomfort, and improve well-being. Aim for at least 30 minutes of activity most days.
Stress management techniques like mindfulness, meditation, and deep breathing can calm the mind and body. Adequate sleep is important, as poor sleep links to more intense premenstrual symptoms like anger, anxiety, and mood swings. Tracking symptoms helps identify personal patterns and triggers. Supplements like calcium, magnesium, and vitamin B-6 may ease symptoms, but consult a healthcare professional before starting any.
Knowing When to Seek Support
While emotional fluctuations before a period are common, seek professional medical attention if symptoms are severe or debilitating, significantly interfering with daily life, work, or relationships. This also applies if self-care strategies are ineffective or symptoms worsen.
Concerns about persistent depression, anxiety, or suicidal thoughts related to the menstrual cycle warrant immediate professional evaluation. A healthcare provider can diagnose PMS or PMDD and discuss treatments like hormonal contraceptives, which regulate hormone levels and reduce symptom severity. Selective serotonin reuptake inhibitors (SSRIs) are often a first-line treatment for severe PMS or PMDD due to their effectiveness in reducing mood symptoms.
