UK data link severe mental illness to decades of premature, preventable deaths
UK NHS data cited by Rethink Mental Illness show adults under 75 with severe mental illness die about 15–20 years earlier than peers, largely from preventable physical diseases (liver, respiratory, cardiovascular diseases, cancer) and suicide. The gap is driven by poverty, housing, smoking, weight gain from medications, physical inactivity, and fragmented care, with 'diagnostic overshadowing' delaying investigation of physical symptoms. Advocates call for routine physical health checks and integrated, mental-health–informed care as government plans to act move forward.
