Bipolar disorder is a lifelong disease, but unlike diseases such as cancer and leukemia, bipolar disorder does not directly endanger the life of the patient. From a pathological and physiological point of view, bipolar disorder does not cause a direct shortening of the patient’s life expectancy. Patients in the midst of a depressive episode with severe depression may engage in some suicidal and self-injurious behavior, and these risks may directly cause the patient to end his or her life prematurely. Once a patient suffers from severe bipolar disorder, it is recommended that family members take the patient to the nearest local professional hospital for treatment. In general, the average life expectancy of patients with bipolar disorder after receiving professional and systematic treatment is not significantly different from that of normal people, and patients with bipolar disorder can live and work like normal people.
