Evaluation of Chronic Abdominal Pain in School-Age Children

Initial Assessment and Diagnostic Approach

The American Academy of Pediatrics recommends determining if pain is relieved by defecation or associated with changes in stool frequency or consistency to suggest functional bowel disorder 1
The American Gastroenterological Association suggests asking about weight loss, fever, vomiting, diarrhea, constipation, blood in stool, and urinary symptoms to identify potential red flags 2
Chronic stress, as assessed by the American Psychological Association, strongly predicts persistence of functional symptoms in children with chronic abdominal pain 3
Plotting weight and height is crucial, as weight loss is a critical warning sign requiring extensive workup, according to the American Academy of Pediatrics 4

The American College of Gastroenterology recommends limited screening studies, including complete blood count, erythrocyte sedimentation rate, and stool hemoccult, for a child with 3 weeks of pain without red-flag symptoms 2
For diarrhea-predominant symptoms, consider stool for ova and parasites, lactose breath test, and celiac serologies, as suggested by the American Gastroenterological Association 2
A therapeutic trial of fiber (25 g/day) may be both diagnostic and therapeutic for constipation-predominant symptoms, according to the American College of Gastroenterology 5, 6

The American Academy of Pediatrics recommends providing pain control immediately with oral NSAIDs for mild-moderate pain, if no contraindications exist 7, 8
Education and reassurance are essential for functional abdominal pain, including establishing a therapeutic relationship and explaining that symptoms are real but not dangerous, as suggested by the American College of Gastroenterology 5, 6
Symptom-directed therapy, such as antispasmodic medication for pain exacerbated by meals, may be beneficial, according to the American Gastroenterological Association 5, 2

The American Academy of Pediatrics recommends immediately escalating care if weight loss, severe or progressive pain, fever with localized right lower quadrant pain, or signs of bowel obstruction occur 4, 7, 1
Inability to tolerate oral intake or signs of dehydration require urgent evaluation, as suggested by the American College of Emergency Physicians 7

Ignoring psychosocial factors, such as chronic ongoing life stress, can preclude recovery from functional bowel disorders, according to the American Psychological Association 3
Withholding pain medication is an outdated practice that impairs examination without improving diagnostic accuracy, as stated by the American Academy of Pediatrics 7, 8
