Eosinophilic Esophagitis (EoE) is a chronic inflammatory disorder that causes inflammation and scarring in the esophagus and has been associated with food allergens. It requires a multi-disciplinary approach which includes a pediatric gastroenterologist, nurse, dietitian and allergist. The EoE program at UC Davis, led by Sunpreet Kaur, M.D., is devoted to the comprehensive care for children with EoE or GI Allergy with a very active role of the pediatric dietitian and gastroenterologist in ensuring that these patients receive the best care.

The UC Davis Children's Hospital Pediatric Inflammatory Bowel Disease (IBD) Program, led by clinical director Daphne Say, M.D., provides multidisciplinary care and focused disease management for children with Crohn's disease and ulcerative colitis. Our program offers comprehensive, individualized treatments for pediatric inflammatory bowel disease, with the aim of enhancing long-term health and quality of life for children and their families.

Functional GI Disorders is a term covering a variety of conditions of the GI tract manifested by one or more dysphoric symptoms, including chronic abdominal pain, constipation, diarrhea or nausea. Despite these physical symptoms, the essential physiology for growth and development is otherwise normal. These conditions frustrate parents and clinicians alike because there are no blood tests that diagnose them and pharmacologic treatments often fall short of relieving the problems that the child is experiencing.

Under the leadership of Arthur de Lorimier, M.D., the UC Davis Children's Hospital is launching a Functional GI Disorders program. Dr. de Lorimier brings 24 years of experience as a military clinician and pediatric gastroenterologist with training in motility studies of the bowel as well as medical acupuncture. This program will provide comprehensive care with diagnostic approaches and treatments individualized to the patient needs. In addition to traditional diagnostic and therapeutic options in the care of patients, this program also provides alternative treatments that include medical acupuncture (More information below)

Pediatric gastroenterologist Arthur de Lorimier, M.D., was trained in medical acupuncture through the Helms Medical Institute. He practices this ancient Chinese medicine art form in his care of patients with a variety of conditions, including, but not limited to, chronic abdominal pain, chronic nausea and anxiety that comes with these maladies. As a retired Army medical officer, Dr. de Lorimier saw firsthand how medical acupuncture has revolutionized the care of returning war veterans with a variety of conditions including chronic pain, post traumatic stress disorder, substance abuse and chronic anxiety. Many of these patients reported positive outcomes as a result of their acupuncture treatment. This exposure prompted Dr. de Lorimier to pursue this training in order to better care for his pediatric patients without necessarily resorting to medication.

Patients can expect a first time visit to last at least one hour and involve a proper medical history and explanation of planned therapy. Subsequent visits follow, typically on a weekly basis. These visits include the placement of needles in various parts of the body. While the placement of acupuncture needles is not absolutely pain-free, the pain involved is minimal and offset by the usual therapeutic results.
