Mohammad Jami, MD, FAAP, is the Associate Medical Director for the Nutrition Support Team and Intestinal Rehabilitation at Children's Hospital Los Angeles. His practice focuses on nutritional needs of chronically ill children, nutritional support of hospitalized children and intestinal failure.

When the intestines fail, children are not able to gain the nutrition that they need from eating a balanced or a normal diet.

Intestinal failure is most often the result of congenital malformations, removal through surgery, disorders of the intestine that prevent the intestines from moving food effectively through the digestive tract or forms of malabsorption.

The multidisciplinary team of the Intestinal Rehabilitation Program at Children’s Hospital Los Angeles provides comprehensive care for children with intestinal failure or related conditions through the Division of Gastroenterology. When a child’s intestines fail, the task for both the care team and for the child’s parents is to help the child get the nutrition that they would normally obtain from eating a balanced diet.

The team’s goal is to help patients move from intravenous to tube feeding to an oral diet while supporting normal growth and development. The team coordinates care with other services in the hospital and with home care agencies that provide products and nursing care in the home setting.

Intestinal Rehabilitation Services

The primary focus of the Intestinal Rehabilitation Team at Children’s Hospital Los Angeles is to help children with intestinal failure meet their nutritional needs, even when they cannot gain what they need from a normal diet. The services and consultation we provide include:

Inpatient Management and Consultation

For hospitalized patients with intestinal failure, we work with patients to ensure that their nutritional needs are met while they are in our hospital. We also prepare patients and their parents to use nutrition therapies at home. These therapies can include tube or intravenous feeding.

Outpatient Management and Consultation (Including Home Intravenous Nutrition)

In our outpatient clinics, we care for children who need at-home nutrition support.

The Intestinal Rehabilitation Team

The team includes physicians, nurses, occupational therapists, a dietitian and a social worker. The team provides active inpatient and outpatient clinical services, offers educational activities in the hospital and the community and research and quality of care initiatives that will lead to better care for such patients in the future.
