Many people with OCD have neglected themselves for a considerable amount of time. This can have an adverse effect on your physical as well as mental health. In addition, some people try to overcome OCD by using substances, or restricting their diet or fluid intake, as an attempt to control their OCD or because ‘the OCD tells them to’ do certain things. By nature, many people with OCD tend to have an ‘all or nothing’ approach to life and this in itself can lead to periods of feast or famine which can have an effect on general health and wellbeing. It can therefore be helpful to try to improve your general physical health either before or during treatment.
