People with psychosis die, on average, nine years earlier than the rest of the population. The main cause of this reduced life expectancy is not suicide brought on by psychosis but coronary heart disease (CHD) and the death rate from CHD is 90% higher among people with psychosis than among other people. Some of this increased risk is due to the side effects of antipsychotic drugs but it is also due to the unhealthy lifestyles of people with psychosis. Researchers at the University of Pavia, in Italy, studied 123 participants with psychosis. They found that 6.9% had high blood pressure, 20.5% high cholesterol, 6.5% diabetes and 20.3% were obese. 63% smoked, 26% drank every day, 8% did not eat fruit and vegetables and 34% did not exercise on a daily basis.
