What is the primary reason that contributes to the higher mortality rate in people with serious mental illnesses?

The primary reason contributing to the higher mortality rate in individuals with serious mental illnesses is often linked to preventable medical conditions. Individuals with serious mental health issues frequently face significant barriers to accessing healthcare services, which can lead to untreated or poorly managed physical health conditions such as cardiovascular disease, diabetes, and obesity.

These conditions are often preventable, yet they are exacerbated by a lack of regular medical care, poor management of chronic diseases, and the stigma surrounding mental health, which can dissuade individuals from seeking timely help. Additionally, those with serious mental illnesses might engage in behaviors that further compromise their physical health, but the root issue lies heavily in the systemic inadequacies of healthcare systems to provide comprehensive care that addresses both mental and physical health needs.

While genetic disorders and lifestyle choices contribute to health outcomes, and inadequate mental health support plays a role in overall wellness, it is the impact of preventable medical conditions on the population with serious mental illnesses that stands out as the primary factor in the increased mortality rates they experience.
