Gastroenterology and nutrition

From routine to rare: Comprehensive gastroenterology care

Some of the most common ailments in infants, children and teenagers involve the gastrointestinal system (digestive and stomach issues). At CHoR, we care for children with a wide variety of gastrointestinal and nutrition needs. We provide care at the Children's Pavilion in downtown Richmond and at multiple community outpatient centers across central and northern Virginia. Our team offers on-site testing as well as urgent appointments when needed. 

Digestive and stomach conditions we treat

Treatment is tailored to each individual child and family. We work with a large team of pediatric subspecialists to care for all GI conditions, from the common to the complex, including:  

  • Acid reflux 
  • Constipation 
  • Growth failure
  • Chronic idiopathic nausea
  • Functional dyspepsia
  • Cyclic vomiting syndrome
  • Irritable bowel syndrome
  • Pseudo-obstruction
  • Postural tachycardia syndrome
  • Orthostatic intolerance
  • Chronic overlapping pain conditions
  • Tube feeding dependence 
  • Malabsorptive disorders (such as celiac disease) 
  • Bacterial overgrowth 
  • Gastritis 
  • Diarrhea 
  • Vomiting 
  • Eosinophilic esophagitis
  • Congenital malformations

What to expect at your child's first appointment

There are no dietary restrictions for the first appointment.

The first appointment requires a detailed interview and comprehensive physical examination, and may also include blood work and/or a rectal exam. Radiology tests and/or endoscopic procedures will be scheduled for a later date after the first appointment. Please bring notes or test results from the pediatrician (CD of x-rays, blood test results, biopsy slides, etc.)

If you are a physician referring a patient for care or need to contact our team, please email

Support groups

Our goal is to treat the whole child, not just their illness. Support groups can help complement medical care provided at CHoR.
