Poor mood first affects the central nervous system such as the brain, and then affects the vegetative nervous system, the endocrine system and the immune system, and through the intermediary of these systems, finally causes lesions in the internal organs, thus leading to psychosomatic diseases. The etiology and pathogenesis of dysphoria may be related to psychological factors, social factors, etc. It is also believed that it is a protective response of the body to acute stress. What are the preventive efforts for dysphoria? There is a close temporal relationship between psychosocial stressful stimuli and the onset of the disease. In general, there should be an adverse stimulus before the onset of psychosomatic disease, and the adverse stimulus and onset cannot be reversed, in which case the disease would not be caused by a psychological stimulus, and certainly not a psychosomatic disease. In addition, it will not be a number of years after the end of the stimulus before the onset of disease. If a physical illness occurs at this time, it would be a stretch to link it to the earlier stimuli. Poor mood generally does not require special treatment, but family members should help patients through this phase. Psychotherapy is given appropriately to eliminate anxiety. Previous history of affective disorders neurotic depression, etc. should be taken as a precaution to try to avoid the occurrence of postpartum dysphoria or its development into postpartum depression and postpartum psychosis.
