Medical Detective Work: Exposing Munchausen Syndrome by Proxy in a Hospital
A four-month-old infant admitted for severe vomiting and failure to thrive was diagnosed with Munchausen syndrome by proxy after doctors observed his mother inducing symptoms.
A four-month-old infant named Ori was admitted to a pediatric ward experiencing severe vomiting after every meal and a failure to thrive. Despite initial medical evaluations at another hospital, no organic cause could be found, even though medical staff witnessed the episodes. Given the broad differential diagnosis for infant vomiting, the medical team initiated a step-by-step diagnostic process.
Investigation and Observation
Occupational therapists instructed the mother on proper feeding and post-feeding behaviors, but Ori continued to vomit and his weight gain remained stalled. As the hospitalization extended past three weeks, the diagnostic procedures became increasingly invasive. The mother cooperated fully, while the father was largely absent from the hospital.
Seeking a breakthrough, the attending physician asked the mother to take a break and leave the ward for an hour. During this time, the doctor fed Ori, who ate eagerly, remained in his stroller for 40 minutes post-feeding, and did not vomit at all.
The Discovery
Schneider Children's Medical Center features a specialized early childhood eating disorders unit equipped with a one-way mirror observation room. The medical team orchestrated a controlled observation exercise involving a clinical nutritionist.

This behavior pointed directly to Munchausen syndrome by proxy, a psychological disorder where a caregiver artificially produces medical symptoms in a dependent person. Welfare authorities were immediately involved to ensure the infant's safety.
Conclusion and Follow-Up
Intervention involving social services and medical staff is complex in such cases due to high rates of recurrence and the challenge of alternative care. However, subsequent monitoring showed that the intervention succeeded and Ori resumed normal healthy development. The case highlights how pediatric medicine sometimes resembles detective work, requiring direct observation to protect vulnerable infants.
