Suicide is a multifaceted public health problem that, unfortunately, remains the leading cause of death worldwide. Studies show that the rate of mental illness, particularly suicide, is higher among doctors than among the public, and the risk of depression and suicide among doctors has also increased. Interventions such as resilience and mindfulness programs can reduce suicidal thoughts among medical students. Suicide prevention programs should target high-risk groups, such as physicians. Studies have shown that medical students and physicians are at higher risk of suicide than the general population. The prevalence of mental health issues and suicidal thoughts increases during medical school. Psychological factors, such as burnout, depression, anxiety, and hopelessness, can lead to suicidal thoughts. Considering the worldwide significance of this issue and the recent increase in mortality among youthful Iranian physicians, we conducted and investigated the prevalence and possible causes of suicidal ideation among Iranian medical students and graduates in this study. The problem of suicides among Iranian doctors and the sudden increase in the deaths of doctors, especially young people, is dangerous. Suicides among Iranian medical, dental, and pharmacy students have increased in recent years. It may be beneficial to support populations at high risk for suicidal ideation and provide screening for early intervention, as well as raise awareness of the prevalence and impact of suicidal thoughts among male students, school officials, and teachers. Screening should include individuals with a family history of mental health issues and those who are separated from their parents, as these individuals are at increased risk for suicidal thoughts. Reducing the prevalence of suicidal ideation may benefit from smoking cessation interventions and stress-reducing curricula. In addition, studies show that work stress among Iranian doctors and dentists can affect their work and treatment. Controlling and managing occupational stress is vital to prevent future problems, as it can have physical and psychological consequences. High levels of occupational stress among these doctors can also pose a danger to their patients. Identifying the causes of physician suicide can help to control and manage it.
