When to Seek Medical Attention
Premenstrual syndrome is generally not an emergency. Seek medical assessment when symptoms are severe, persistent, or substantially interfere with daily activities or quality of life, particularly when symptoms change significantly from usual patterns. Urgent evaluation is appropriate for severe physical symptoms, fainting, or other sudden concerning changes.

Causes 1
The exact cause of premenstrual syndrome is not fully understood. Symptoms are believed to be related to sensitivity to normal hormonal changes that occur during the menstrual cycle rather than simply to abnormal hormone levels. Changes in estrogen and progesterone may influence brain chemicals and contribute to mood, physical, and behavioral symptoms. Stress, sleep problems, and other lifestyle factors may affect symptom severity but are not considered the sole cause.
Hormonal Imbalance
Risk Factors
Risk factors and factors associated with greater symptom burden include a personal or family history of PMS, sensitivity to normal hormonal changes, and certain mood disorders. Symptoms may also be influenced by stress, poor sleep, limited physical activity, and other lifestyle factors. PMS can occur during the reproductive years and its severity may change during different stages of reproductive life.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis of premenstrual syndrome is usually based on the recurring pattern of physical and emotional symptoms in the days before menstruation and improvement after menstruation begins. A symptom diary kept for several menstrual cycles can help establish the timing and severity of symptoms. There is no single laboratory test that confirms PMS. A healthcare professional may evaluate other conditions when symptoms are unusual, severe, persistent, or not clearly linked to the menstrual cycle.
Prevention
Key Prevention Tips
PMS cannot always be prevented because it is related to normal menstrual-cycle changes and individual sensitivity to those changes
Regular physical activity, adequate sleep, balanced nutrition, limiting factors that worsen symptoms, and effective stress management may help reduce symptom burden
Keeping a menstrual and symptom record can help identify recurring triggers and support early discussion with a healthcare professional when symptoms interfere with daily activities
Prevention Guidance
PMS cannot always be prevented because it is related to normal menstrual-cycle changes and individual sensitivity to those changes. Regular physical activity, adequate sleep, balanced nutrition, limiting factors that worsen symptoms, and effective stress management may help reduce symptom burden. Keeping a menstrual and symptom record can help identify recurring triggers and support early discussion with a healthcare professional when symptoms interfere with daily activities.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
