Hi,
It is difficult to provide a specific diagnosis without the results of the MRI and blood work, but some possible causes of persistent diarrhea, vomiting, and fatigue in an 11-year-old child could include:
* Infection: A viral or bacterial infection could cause these symptoms. If the child has recently traveled to an area with poor sanitation, food or waterborne illnesses may be a possibility.
*
Inflammatory bowel disease (IBD): Crohn's disease or
ulcerative colitis are two types of IBD that can cause
chronic diarrhea,
abdominal pain, and fatigue.
* Food allergies or sensitivities: Some children may develop diarrhea, vomiting, and fatigue due to an intolerance or allergy to certain foods.
* Autoimmune disorders: Certain autoimmune disorders can cause chronic diarrhea, vomiting, and fatigue.
* Parasitic infections: Parasites such as giardia can cause diarrhea, abdominal pain, and fatigue.
It is good that the child is seeing a
rheumatologist, as some autoimmune disorders can cause gastrointestinal symptoms. It is important to continue working with medical professionals to find the underlying cause of these symptoms and develop a treatment plan.
Take care. Hope I have answered your question. Let me know if I can assist you further.

Dr. Priyanka, General & Family Physician
