Impact of Diet and Nutrition on Growth

It is important that children with ulcerative colitis (UC) eat a balanced diet, since diarrhea and loss of nutrients may lead to malnutrition.  Because eating often exacerbates abdominal pain and diarrhea, children with ulcerative colitis may often avoid eating.  Improper diet and frequent diarrhea could lead to deficiencies in some nutrients.  Ulcerative colitis can also affect how well nutrients are absorbed from the intestines. 

Growing slowly is a specific issue facing children with inflammatory bowel disease (IBD).  Between 6% and 10% of children with ulcerative colitis experience growth impairment.  Deficiencies in vitamin D or calcium could lead to bone problems.  In addition to the influence of malnutrition, some medical treatments (e.g., corticosteroids) can also affect a child's growth.
