A common reason that those suffering from serious mental illness are “noncompliant” with medication is the side effect of weight gain. Of those who stay on their medication, weight gain can be the most distressing side effect. According to the National Institutes of Health, mentally ill people are 50% more likely to be overweight/obese than the general population. Weight gain has significant negative health implications and is one reason why on average mentally ill people die younger than non-mentally ill people.
