Premenstrual syndrome is a syndrome characterized by repeated cycles of emotional, behavioral and somatic disturbances during the luteal phase, which naturally disappears after the onset of menstruation. This symptom may be due to neurological factors, ovarian hormone imbalance, neurotransmitter abnormalities, etc. Patients may experience headache, breast tenderness, emotional instability, irritability, easy fatigue, and poor concentration. If the symptoms are not serious, the symptoms of tension and pain can be improved by adjusting lifestyle, adjusting sleep habits, and correcting negative emotions. If the symptoms are more severe, patients can be treated with birth control pills, serotonin reuptake inhibitors, gonadotropin-releasing hormone agonists and other medications under the guidance of a doctor. Patients need to go to the hospital and follow the doctor’s instructions for treatment, and the use of medication should be strictly followed.
