Target Audience:

This activity has been designed to meet the educational needs of pediatric gastroenterologists and other healthcare providers involved in the care of patients with irritable bowel syndrome (IBS).

Learning Objectives:

After completing this activity, the participants should be better able to:

  • Recognize the symptoms of carbohydrate malabsorption across the age spectrum.
  • Incorporate current diagnostic strategies into clinical practice to differentiate among the various carbohydrate malabsorption disorders.
  • Compare and contrast the clinical presentation, diagnosis, and management of carbohydrate malabsorption from other causes of functional GI symptoms seen in pediatric clinical practice, particularly in patients with suspected IBS.

For the past 30 years, the focus of my academic activities has been the diagnosis and treatment of functional and motility disorders in children of any age. I have pioneered the use of manometry and barostat testing to evaluate motor and sensory function in the upper and lower GI tract. I have held leadership positions within NASPGHAN, ANMS, AGA, Brain-Gut Club, and ABP. I have chaired both the Rome III and Rome IV Child-Adolescent committees, and I have had more than 280 peer-reviewed and invited manuscripts in the field of functional and motility disorders in pediatrics. I was awarded the Master Award in Gastroenterology by the AGA. I was the President of NASPGHAN from 2014 to 2016.
