The mind–body connection
Mental ill-health is associated with a greater burden of physical disease. The reasons are multiple—and many of the risks are detectable, treatable or preventable.
People living with severe mental disorders may die 10–20 years earlier than the general population. The World Health Organization reports that most of these premature deaths are due to physical health conditions, many of which are preventable. UK public-health analysis estimates that around two-thirds of deaths in people with severe mental illness are from preventable physical illnesses.
These figures relate particularly to severe mental illness—such as schizophrenia, psychosis and bipolar disorder—and should not be applied uncritically to every person experiencing anxiety, depression or ADHD.
Why risk can increase
Diabetes, high blood pressure, abnormal cholesterol, obesity and cardiovascular disease occur more commonly in people with severe mental illness. Risk may reflect illness biology, medication, deprivation, stress and barriers to preventive care.
Some antipsychotics and other psychotropic medicines can contribute to weight gain, changes in glucose or lipids, altered blood pressure and other physical side effects. This does not mean medication should be avoided; benefits, risks and appropriate monitoring should be considered together.
Research links some mental disorders with altered inflammatory, immune and stress-response pathways. These mechanisms may contribute to physical disease, but the relationships are complex and often bidirectional. Inflammation is one part of the picture—not a single proven explanation.
Sleep disruption, smoking, alcohol or substance use, reduced activity and difficulties maintaining a balanced diet may increase risk. Symptoms, poverty, trauma, medication and the environments people live in all influence these behaviours; this is not simply a matter of willpower.
Physical symptoms can sometimes be attributed too quickly to anxiety or mental illness. People may also find screening, appointments or self-management harder to access. Listening carefully and investigating proportionately helps avoid physical illness being missed.
Physical illness can worsen mood, anxiety, sleep and cognition, while mental ill-health can make physical conditions harder to manage. Treating either in isolation risks missing what sustains the other.
