Mental health condition

Life expectancy with severe mental illness

Severe mental illness, including schizophrenia and bipolar disorder, is associated with a significant gap in life expectancy, most of which comes from physical health conditions rather than the illness itself.

Important. The figures below describe statistical associations across populations, drawn from published research. They are not a prediction about any individual. Outcomes vary widely between people in both directions, and many factors are modifiable. This is not medical advice. For personal guidance, speak to a GP.

What the research suggests

Research, including analyses in Lancet Psychiatry, associates severe mental illness with a notable reduction in average life expectancy, often cited in the region of ten to fifteen years. Much of this gap is driven by higher rates of cardiovascular disease, smoking, and barriers to physical healthcare, which means a large part of it is potentially modifiable.

What changes the outlook

Access to physical health checks, smoking cessation support, cardiovascular risk management, and continuity of care can narrow the gap substantially.

Can I get a personal estimate?

This tool gives a statistical estimate as a five-year range based on your overall profile, including severe mental illness alongside your other answers. It is not a prediction. For personal medical guidance, speak to a GP or specialist.
