Editing Crohn's disease (section)

=== '''Lifestyle''' ===

* Dietary
** Low-fibre diet can help diarrhoea and pain during an acute exacerbation
** Frequently need vitamin supplementation - especially vitamin D, B12, folic acid, iron, zinc, calcium, magnesium
** Exclusive Enteral Nutrition (EEN) is used as an alternative to pharmacological induction agents. This consists of exclusive intake of elemental or non-elemental resource drinks during an acute flare. This is first-line induction therapy in children and second-line in adults (when steroids or biologics are contraindicated), for mild flares. The mechanism is not fully known but may be reduced exposure to antigens in food, altered microbiota, and improved nutritional deficiencies.
** Has been research into elemental diets to maintain remission, but not thought to be particularly important
* Smoking
** Clearly affects disease course - increases incidence of relapse and failure of maintenance therapy, and is associated with severity of disease
