If further treatment is required, a combination of an immunosuppressive drug (such as azathioprine) with mesalazine (which may also have an anti-inflammatory effect) may be needed, depending on the patient. Controlled release budesonide is used for mild ileal Crohns disease. Nutritional and dietetic therapies
Exclusive enteral nutrition is a first-line therapy in pediatric Crohns disease with weaker data in adults. : 331  Evidence supporting exclusive enteral nutrition in ulcerative colitis is lacking. : 333 Nutritional deficiencies play a prominent role in IBD. Malabsorption, diarrhea, and GI blood loss are common features of IBD. Deficiencies of B vitamins, fat-soluble vitamins, essential fatty acids, and key minerals such as magnesium, zinc, and selenium are extremely common and benefit from replacement therapy. Dietary interventions, including certain exclusion diets like the specific carbohydrate diet (SCD) can be beneficial for symptom management. Dietary fiber interventions, such as psyillium supplementation (a mixture of soluble and insoluble fibers), may relieve symptoms as well as induce/maintain remission by altering the microbiome composition of the GI tract, thereby improving regulation of immune function, reducing inflammation, and helping to restore the intestinal mucosal lining.Anaemia is commonly present in both ulcerative colitis and Crohns disease. Due to raised levels of inflammatory cytokines which lead to the increased expression of hepcidin, parenteral iron is the preferred treatment option as it bypasses the gastrointestinal system, has lower incidence of adverse events and enables quicker treatment. Hepcidin itself is also an anti-inflammatory agent. In the murine model very low levels of iron restrict hepcidin synthesis, worsening the inflammation that is present.
These treatments had no effect on quality of life, emotional well-being and disease activity. The need for these approaches should be individually assessed and further researched to identify subgroups and determine type of therapy that may benefit individuals with IBD. In adolescents population such treatments may be beneficial on quality of life and depression, although only short-term effects have been found, which also imposes the need for further research. Treatment standards
Crohns and Colitis Australia, the peak body for IBD in Australia, where prevalence is one of the highest in the world, reviewed the quality of care for patients admitted to Australian hospitals. They found that only one hospital met accepted standards for multidisciplinary care, but that care was improved with the availability of even minimal specialised services. Prognosis
While IBD can limit quality of life because of pain, vomiting, and diarrhea, it is rarely fatal on its own. Fatalities due to complications such as toxic megacolon, bowel perforation and surgical complications are also rare.. Fatigue is a common symptom of IBD and can be a burden.Around one-third of individuals with IBD experience persistent gastrointestinal symptoms similar to irritable bowel syndrome (IBS) in the absence of objective evidence of disease activity. Despite enduring the side-effects of long-term therapies, this cohort has a quality of life that is not significantly different to that of individuals with uncontrolled, objectively active disease, and escalation of therapy to biological agents is typically ineffective in resolving their symptoms.
