Disorders of the Esophagus

Actual symptoms depend on the age of the patient. The diagnosis process may include a blood work, radiological studies, and an endoscopic exam. Once a diagnostic is has been made, we create an individualized treatment plan based on each patient's needs.

Disorders of the Stomach & Intestine

Some of the common systems of stomach and intestinal disorders include abdominal pain, poor weight gain, inadequate growth, indigestion, nausea, vomiting, diarrhea, constipation, presence of blood in the stool, and a variety of other, often age-related symptoms. Once we have a diagnosis, we create an individualized treatment plan.

Disorders of the Liver & Pancreas

Common symptoms of disorders of the liver and pancreas include jaundice, weight loss, abdominal pain, abnormalities in the blood tests, and other symptoms, often depending on the age of the patient. Those conditions usually require performance of a variety of blood tests, and specialized radiological studies, such as MRI, ultrasound and nuclear scans.

Nutritional Disorders

Symptoms of nutritional disorders include low weight, excessive weight gain, and inadequate growth. The treatment plan often includes dietary changes and a referral to a dietitian.

Our medical services are designed to treat digestive and nutritional disorders in infants, children and teens from age 0 to 21. You will find that we work hard to stay current with new developments in our field, and to provide you and your child with the very best service and treatment.
