Schizophrenia, although a disabling disorder in itself, is associated with a host of comorbidities that further burden the patient.[APA, 2013; Buckley et al., 2009; Tsai & Rosenheck, 2013] These include psychiatric and somatic conditions.[Buckley et al., 2009; Tsai & Rosenheck, 2013; Leucht et al., 2007; APA, 2013]

The burden of comorbidity associated with schizophrenia means that it is important to focus on raising the awareness of physicians about the association between schizophrenia and other physical illness, and ensuring that psychiatrists are also skilled in the diagnosis and treatment of non-psychiatric conditions.[Leucht et al., 2007]
