The Western Montana Clinic knows children are not just little adults.  Children's bodies have unique medical needs.  Kids express their concerns and pain differently than adults and they cannot always answer questions. 

The specialized training and experience in pediatric gastroenterology are important.  A pediatric gastroenterologists knows how to examine and treat children in a way that makes them comfortable and relaxed.  A pediatric gastroenterologists can provide the best care for your child to not just diagnose and treat the issue at hand but also consider the growth, maturation, physical and emotional development of your child.

What is a Pediatric Gastroenterologist?

Pediatric gastroenterologists are medical doctors who have a certification in pediatrics for the American Board of Pediatrics, and in gastroenterology and nutrition.  They receive years of additional training in the treatment of infants, children and teens with digestive, liver and nutritional disorders.  They also treat bleeding, swallowing problems, or other problems encountered in the intestines.  They have extensive expertise in managing nutritional problems in children, including placement and management of feeding tubes and intravenous nutrition and diagnosing and treating infants, children and teens with liver disease.

Pediatric gastroenterologists are specially trained to perform diagnostic tests of a child's digestive system.  Special instruments, such as endoscopes, are used to examine the inside of the digestive tract or obtain tissue samples (biopsies).  Endoscopic procedures they perform include esophagogastroduodenoscopy and colonoscopy.
